It's most likely your blower motor control module. Easy fix! Remove the kick plate under the glove compartment and the module is right next to your blower motor - remove the two screws and it will drop right out. Disconnect the wire harness (2 wires) and replace. Good luck!

Front fan just stopped working...back one is fine.


{: ) It could be the BLWR fuse 40amp at the underhood fuseblock, a faulty blower resistor assembly, or the front blower motor itself.

Air conditioner blows hot air after 30 seconds on drivers side, on start up. Passenger side works fine. Air blows out correct vents per setting on air conditioning. Replaced blend door actuator on drivers...


I have had this problem. I am not a mechanic...so to correct the issue temporarily, I simply turn off the car and restart. This has worked everytime for me. In extreme cases, I think you can also remove the AC fuse and start the car, which will also reset the computer. I also think that by taking the climate control off the "AUTO" setting has worked in the past.

Get the climate control computer relaced or reprogrammed. There is a good chance that when your vehicle was jump started it fried the climate system.
