Ac issues advice...

Hello all.

Ok my ac in the front goes off and then comes back on. It does it randomly. Now for the last few days it went off and now won't come on. What can it be? The rear ac is fine. Thx

You mean like the blower's not blowing air? Do you have a multimeter ? Gonna have to start tracing voltage back from the blower motor to the switch. Could be something simple like the blower motor resistor, or could be the blower motor itself? You can also look at the HVAC module in ForScan and see what it's doing.

Yes sorry. No air blowing out of front vents. I just wiggled those four wires under the passenger side and it started blowing air. What could it be under there? Thx

The speed control resistor is there stuck in the side of the box, as well as the blower motor itself.
