My 2010 kia blower fan stopped working but was fine last week. This occurred a few times in past. Works fine then stops blowing ag
Blower not working.
Was ok two days ago. This occurred different occasions over the year in 2016. Works great. Then two months will stop working for maybe say 2 to 3 days then start working again. Bad blower relay?
My car has 80000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
The blower switch and the plug connection on the back of the switch, as well as a faulty blower motor are likely, too. I would check the blower motor first as you can easily power the motor directly to see if it runs. If the circuit includes a blower motor resistor block, of course be sure to check if the resistor block has continuity (specified resistance in ohms) at each position. If the blower motor runs, I would check the switch as occasionally there will be a bad connection at the switch that eventually causes the blower not to work. The relay is easy to test and if it works consistently as commanded, you can assume there is no intermittent fault. Obviously, check the fuse in the circuit, too, but if the fuse is bad, that means there is a problem in the circuit that will have to be repaired. Fuses blow due to electrical faults (e,g., short circuits). If you desire, a certified mechanic from YourMechanic can diagnose the problem you are having in an electrical component diagnostic.

Essentially an on/off switch, the blower motor relay`s reactions start and end the heating process in HVAC systems by controlling the flow of current between the power source and the motor. Blower motor relays tend to wear out over time from the stress of constantly flicking back-and-forth.
The most common reasons a Kia Soul radiator fan isn`t working are the fan assembly, the fan clutch, or the coolant temperature sensor.
The blower motor relay is the electrical switch that is used to supply the power for the vehicle`s blower motor. The blower motor is the component responsible for pushing air through the vents of your vehicle`s heating and air conditioning systems.
Springs will loose resiliency with time. Relays can also fail due to poor contact alignment and open coils. Selection of the proper relay type for a given application is the most significant factor affecting relay reliability. Many poor design practices are used when designing them into circuits.
If the relay fails it will cut off power to fuel pump and ignition system, which will result in a no power, and therefore no start condition. You may find that turning the key may power on the accessories, and may even crank the engine.
The most common reasons for a radiator fan not working can be a blown-out fuse, a bad relay, or a broken wire. The faulty coolant temp sensor might also be a reason behind it.
Problems include dirty filters, broken wires, poor voltage supply and faulty limit switch or capacitor. You can test your limit switch with a multimeter, and clean the blower motor`s wire coils. If this doesn`t work, you may need to replace your furnace blower motor.
The electrical contacts can wear down after years of constant use. Relays can also overheat, especially if too much electricity flows through the relay due to a problem with another AC component. It`s not unusual for a faulty part to cause a relay to burn out or even melt its plastic housing.

Windshield wipers stopped working. They’ll suddenly stop working then suddenly start working again. Has been happening for a week.
ANSWER : The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Front A/C fan not blowing, but front seat cooling and rear A/C fans are working.
ANSWER : What you are describing sounds like a failure of the blower motor that circulates air in the HVAC system, however, there are certain faults that could occur in the electric circuit that powers the blower motor. If power is reaching the blower motor when the blower switch is in the on position and the blower motor is not functioning as intended then the blower motor is condemned and replaced. On the other hand, if there is no power, then the blower switch and the plug connection on the back of the switch, as well as the rest of the circuit should be inspected. If the circuit includes a blower motor resistor block, of course the resistor block has to be checked for continuity (i.e., specified resistance in ohms) at each position. If equipped with a relay in the circuit, that is easy to test and if the relay works consistently as commanded, you can assume there is no fault there. If you want these diagnostic steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a non functioning blower motor diagnostic/replacement and the responding mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.
Front fan is not blowing any air just stop working. I turned the air on and heard a popping sound. Rear is working blowing cold
ANSWER : It’s possible the blower motor, or possibly just the blower resistor block, has failed. To determine which of these (or other) possibilities are involved, please request a fan/blower motor diagnostic and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Defroster works – hot or cold air depending on what temperature you have it on, but not vent or heat. 2011 Ford Edge
ANSWER : Hello – your symptoms suggest that the HVAC blower motor resistor has failed. The blower motor resistor limits fan motor speed for the Low and Medium settings, but is not involved at the Max setting. Since defrost on most cars uses the Max fan setting, the blower would work for Defrost but not for Heat or Vent. I recommend a fan not working inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs.
My car ac a year ago stopped working on settings 123 only works on 4 I did the research so I do know it is the blower motor an ha
ANSWER : In your application, there is a replaceable blower motor resistor block. The resistor block permits multi-speed operation of the fan. If some fan speed settings work, but not others, the first thing to do is test the resistor block with a volt ohmmeter. If you desire testing, and replacement, as needed, please request a blower motor/resistor block diagnostic and the responding certified mechanic will get this taken care of for you.
With regard to the A/C system, if gauge pressures (high and low) are normal when the system does operate, there are really only two principle possibilities for intermittent operation. One is circulating moisture in the system (due to a saturated dryer) which periodically freezes (and thaws) at the expansion valve and the other is a failure in the A/C control system, that is the clutch, sensors, and other electronics that control the compressor cycling. The cause of the problem can be readily found if you request an A/C system diagnostic. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Blower Motor only working on highest speed.
ANSWER : You mentioned that you started to smell something. This may be a sign that the blower controller or the resistor was burnt out when it was hooked up wrong. You should try replacing the blower controlling resistor that you hooked up wrong. But like you mentioned, it could also be a fuse problem that has shorted. If you would like to have this looked at, have a certified technician, like one from YourMechanic inspect the wiring and determine what should be done.
1999 Jeep Cherokee idles fine, loss of power at higher rpm. Cruise control stopped working at the same time. Stalls at stopped when revved up from idle.
ANSWER : The cruise control switch could have an issue and may have shorted the contacts inside the switch terminals. For the engine stalling after pushing on the throttle pedal, there could be either a vacuum leak on the engine or the air idle control valve could be stuck causing the idle to not return correctly. Check all of the vacuum lines and the brake booster for any vacuum leaks. Tighten all of the intake bolts to ensure that they are tight and not loose. A loose intake bolt, broken or cracked vacuum hose will cause the engine idle to run erratic making the idle not steady. If you need more assistance with your engine idle issue, then seek out a professional, such as one from Your Mechanic, to help you.
