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
Front ac quit, fan stop working will not blow cold air. Rear is working fine. I turned on the ac and heard a pop and then there was a burnt smell like a fuse or something had blown. Front is not doing anything only the back.
Experienced mechanics share their insights in answering this question :
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 your air handler is running but not blowing air, there are two likely scenarios; either a broken AC blower belt or an issue with the motor itself. If the air handler is humming or buzzing, but not making the mechanical sounds of a motor running, you`re most likely talking about an issue with the motor itself.
Lots of things can cause your blower to have trouble, especially if it gets too dirty. A fan clogged by dirt, a stuck wheel, broken motor, or a loose fan belt are all common problems that reduce the amount of airflow you feel coming from your vents.
Car AC Not Blowing Cold Air: A Bad Fuse
Find the fuse associated with the A/C blower motor. If the blower motor fuse is still in-tact, your problem is located elsewhere. If the fuse is blown, simply replacing the fuse with an identical fuse of the same amperage rating could get your system working again!
You Have Cold Air Blowing Out The Vents When The Heat Is On Because of a Dirty Air Filter. Hiding in the filter of your heating system is dirt and debris. If you aren`t cleaning it regularly, this will accumulate over time, leading to problems with your heating system`s efficiency.
If the hum occurs when the motor is on but not turning, the capacitor may be damaged and, if so, should be replaced. This could result from a poor quality capacitor or a blocked filter. Humming when the blower is off usually indicates that the pilot light needs to be readjusted to the appropriate level.
It is usually located inside the blower compartment on the side of the blower motor. Be cautious as the housing may be hot. If the button is popped up, press it down.
This can be caused by a variety of factors including a blown fuse, loose wiring, a problem with the dual or single capacitors, or a defective motor. If you suspect that your ceiling fan has electrical issues, you`ll need to have it repaired by a qualified electrician.
One of the first symptoms of a problem with the blower motor relay is a blower motor that does not function. As the relay is the switch that supplies current to the blower motor, if it fails internally, then power may be cut off from the blower motor circuit causing the motor to no longer function.
This can be caused by a variety of factors including a blown fuse, loose wiring, a problem with the dual or single capacitors, or a defective motor. If you suspect that your ceiling fan has electrical issues, you`ll need to have it repaired by a qualified electrician.
* If your HVAC is running but NO air is blowing through the vents, check the filter. If it`s clogged, replace it. You should be replacing the filter on a regular schedule.

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.

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.
Air conditioning blowing mildly cold air on the coldest setting, turned off/on again, now blowing cold air, should it be checked?
ANSWER : If you are getting ready for a long trip and suspect the cooling fan may be not coming on for the radiator and a/c then you should have the a/c and cooling system performanced checked before trip. Nothing worse than breaking down when out of town in a strange area.
everytime I turn my car on the ac starts to blow air even if I switch it off. it won’t blow cold air or heat.
ANSWER : Hi there. Based on your question and input, it looks like your AC control switches are damaged, causing the vents to activate even if the switch is not activated. This is sometimes an electrical problem, as it could be triggered by a damaged electrical relay. You might want to have a professional mechanic complete an AC is not working inspection, so they can determine what is causing this issue you’re experiencing and recommend the right repair.
I have a 2013 cadillac xts. The ac stopped blowing cold air a couple years ago and all i had to do was turn it off for five minute
ANSWER : There are innumerable things that can go wrong with the A/C system and so the best thing to do is request an air conditioning system inspection and the responding certified mechanic will get this resolved for you. The possibilities that might account for the problems you are experiencing range from a malfunctioning expansion valve, low state of charge, moisture in the system, refrigerant leaks, faulty cooling fans on the condenser and so forth. If there is a leak, it will have to be repaired because leak rates in newer systems are very, very small and they have to be because the installed refrigerant charge is much lower than in years past. The only way to pin it down is to get the system professionally inspected and diagnosed. Once diagnosed, the mechanic will be in a position to give you a repair strategy to get the A/C fully functioning and he or she will estimate the cost of the required repair. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
When I turn on my AC the radiator fans do not turn on. The fans do come on when the car warms up so I know they are working and the fuses are good. The AC compressor does come on and the air blows ice cold when the car is moving. Car is a 2006 Chrysler Sebring Sedan 2.7l v6.
ANSWER : The control circuit for the fans needs to be checked. For example, there is usually a condenser fan relay in the A/C electrical controls. There could be a fault with that relay and/or wiring problems, perhaps even just a loose connection, blown or loose fuse, and so forth. To resolve something like this, the recommended service is an electrical component diagnostic. If you request that diagnostic service, the responding certified mechanic will get the problem pinpointed and resolved. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
AC stopped blowing cold air
ANSWER : Hello! There are a few potential causes of your problem that I recommend inspecting. I would first check the refrigerant levels of the system, to ensure that it has adequate pressure. If the pressure is low, I suggest having a technician inspect the system for leaks; I think this is unlikely, since the AC stopped working so suddenly. The most likely case is that there is an electrical issue, such as a blown fuse or open circuit, although I would also recommend checking the performance of the AC compressor. Please keep in mind that the Federal Government requires all AC work or repair to be done by an EPA-certified technician. YourMechanic can send an EPA-certified technician to the location of your Expedition to inspect your AC system, and recommend the best path to repair.
My heater is blowing air through the driver side air vents but is blowing cold air through the passenger side and rear console ven
ANSWER : Hi there:
Climate controlled vehicles have multiple electrical relays that open and close vents to maintain the desired temperature. In some instances, these relays can wear out overtime. However, it’s also common for debris to clog up vents (especially side vents) which may restrict the flow of cool air. The best way to determine why your AC is not working efficiently, it might be best to have a professional mechanic complete a AC inspection; so they can pinpoint the source of your issues and recommend the right repairs.
