Experienced mechanics share their insights in answering this question :
Hello, thank you for writing in. The vehicle is equipped with an electric transfer case, in which something has gone wrong. The fact your are stuck in 4WD, is because the computers programming demands the system shuts down during this time. You will want to have the vehicle scanned for diagnostic codes to find out what about the system is failing. The codes can be removed to try and temporarily switch back to 2WD. Be careful with this, as shutting down the system when there is a fault is a safety matter. For more help with diagnostics, contact our service department to schedule an appointment.

When the 4WD light appears, it is letting you know that there is an issue with the 4WD system and it must be handled promptly. Another reason why this light may occur is an incomplete shift in gears. This is confusing and damaging to the engine and could result in your 4WD service light flashing continuously.
The “Service 4WD System” message indicates a problem with the 4WD system that should be properly diagnosed and repaired. When the ignition key is turned from OFF-RUN-START and is released back to the RUN position after the vehicle starts, the 4WD warning light should go on for 1 to 2 seconds and then go out.
Best Answer. if the red light is blinking it means you need to either charge the battery or get a new 1.. if its a good battery try cleaning the termials.
A flashing indicator light is typically caused by wiring or an electrical component like the controller, a faulty motor or fork, a speed sensor, or a position switch. Many 4WD units have an actuator located on the front axle to lock and engage the front axle for 4WD.
To reset the Change Oil light turn the ignition on but do not start and then push the gas pedal 3 times. The Service 4WD light is most likely the 4WD switch on the dashboard. If the lights are acting funny then the switch needs to be replaced. There is a quick fix for it though.
To engage low range, stop your 4×4, put it into Neutral or Park, and use your dial to switch from either 2H to 4L, or (assuming you`ve been in 4H in the lead-up to the low-range terrain you`re about to tackle) 4H to 4L.
To put them into 4 Wheel Drive High you need to be drive around 7 – 30mph and pull down the lever from 2H to 4H. If you need to put them into 4 Wheel Drive Low you need to be Parked and then shift into Neutral. Then you will pull the lever down from 2H to 4L. The Ram 1500 is a part time 4×4 System.
Here`s the answer: You can use either “2WD” or “Auto” all the time. If you don`t have any need for extra traction, using “2WD” may save a tiny bit of money on fuel and possibly some wear and tear on the four-wheel-drive components. “Auto” in your truck operates in two-wheel drive by default.
Although there is no maximum speed limit when using 4WD high in a Ram 1500, it is best not to exceed 55 mph (89 kph). What is this? As for 4WD low, you should never go over 25 mph (40 kph).
Faulty RAM
If your RAM is faulty or not functioning correctly, it can cause a red light to appear on your motherboard. Some signs that your RAM may be faulty include: The computer is displaying error messages related to memory or RAM. The computer is unable to start up or boot into the operating system.
A lot of the time, a flashing 4WD light is no reason to be alarmed, because it simply means that the system is working as designed. On vehicles where four-wheel drive is only activated on demand — that is to say, when traction conditions require it — this light shows up to tell you that it`s been activated.
Transfer Case Control Module (TCCM) is the brain behind the electronically shifted 4WD systems. The TCCM processes the shift request from the dash mounted mode selector buttons, executes the shift, and verifies the shift was completed. Replace your current failing or faulty item with this direct replacement.
Faulty Switch – If the switch itself is bad, it won`t let current flow from the battery to the solenoid, and won`t allow the transfer case to engage four-wheel-drive. Even if the switch feels fine, it could be corroded, dirty, or broken internally.
The 4WD system is engaged or disengaged by rotating the control for both front wheel hub locks from the FREE or LOCK position, then manually engaging or disengaging the transfer case with the floor-mounted shifter. For increased fuel economy in 2WD, rotate both hub locks to the FREE position.
Have someone stand outside of the car and watch the tires. As you drive into the tree, your tires will try to get traction. If all four wheels of your car are moving, your four-wheel drive is doing its job!
Shifting into low-range four-wheel drive is a little more involved than shifting into high-range four-wheel drive. Drivers will need to shift the transmission into neutral to disconnect torque to allow the transfer case to shift gears.
You can move the control from 2H to 4A or 4H at a stop or while driving.
All-wheel drive, or AWD, refers to a system where all four wheels can gain traction independently of each other. The difference between AWD and 4WD is that AWD is typically always on while you can toggle between having 4WD on and off.
AWD systems use three differentials, center, front, and rear to distribute power from the transmission to the wheels. 4WD uses two differentials and a transfer case to get power from the engine to the wheels, but in this case, the wheels spin at the same speed when the system is engaged.
Used 2004 Dodge Ram Pickup 1500 Overview
The Used 2004 Dodge Ram Pickup 1500 comes with rear wheel drive, and four wheel drive. Available transmissions include: 6-speed manual, 5-speed manual.
Most four-wheel drive vehicles allow you to switch from 2WD to 4WD while the car is in motion, but only under certain circumstances. Take the following precautions when switching from 2WD to 4WD while moving: Reduce to a slow speed, never exceeding 60 mph. Make the switch while driving in a straight line.
The AWD switch may be turned on or off while the vehicle is moving.
A full-time 4WD system, for example, can handle high speeds because it`s designed to operate in all conditions. However, if you`re using a part-time 4WD system, high-speed driving on dry roads could potentially cause drivetrain damage due to the binding effect in the system.
Even the 2021 RAM 1500 1/4 mile time of 16.0 seconds is good for its size and so is the top speed of 118 mph. The 2021 RAM 1500 TRX Crew Cab is the real star of performance with a 0-60 time of 3.8 seconds.

Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.
No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.
Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.
Just replaced head gasket, changed crack sensor new plugs. The check engine light is on, but dim, the only other light that the dash is a normal battery indicator. The fuel pump is not running when switch is turned on, the power windows don’t work, it turns over but not firing. It’s like only one part of the system is working. Also the heater fans work even if the switch is off.
ANSWER : I would first look at the diagnostic trouble codes. Those codes are available because the check engine light is on. If the fuel pump is not running (momentarily) at key on, that fault alone will prevent the car from starting as there will be no fuel pressure. Pump output and pressure can be directly tested and you can also check for electrical power to the pump. To find out why the engine will not run, the recommended diagnostic is a no start diagnostic. If you request that service, the responding certified mechanic will get this taken care of for you.

on a 1970 Lincoln mark iii Interior lights wont turn on and warning lights are very dim and doorlock button makes buzzer go on
ANSWER : Hi there. Although the electrical systems on older vehicles tend to be much simpler in design, in many cases, issues like you’ve described can be very tricky to trace. It could possibly be something as simple as an expose wire creating an electrical short or a faulty relay that is not completing an electrical circuit. I wish we can help you further, but the best advice I can offer is to have one of our mobile mechanics come to your location and complete an electrical problems inspection.
I am not getting any power when I turn the key to the on position. there is no dash lights only check engine lite comes on.
ANSWER : The problem of having erratic electrical issues with this year Bronco they have problems with the ignition switch losing contact. You should check and replace the ignition switch. When the switch is removed you should check linkage rod and electrical connector for problems and repair as needed along with replace the ignition switch.
