A/C only works while driving. 2006 jeep liberty 3.7

[James R Couchenour]

Does anyone know what would cause the A/C to only work when driving?

 

[daves06lrenegade]

Low refrigerant, bad fan clutch, compressor worn out... The list goes on...

Welcome James to the forums.
When you turn on the A/C or set to re-circulation mode, is the electric fan running?
Probably the best place to start, is having an a/c shop test the high & low side specifications.

Thank you for the info. The crazy thing is it’s ice cold when I’m driving, but come to a stop or sit idle and it doesn’t blow at all.

I think his info is that if the contained system refrigerant is low, that’s what happens.

i guess cold is relative to the OP unless it's measured with a thermometer.
The engine produces so much heat that you'll feel a difference at a stop.
Who knows where your location is? perhaps you're in the desert or somewhere hot.
Too many variables.

What's happening is I start the vehicle and turn on the A/C and I don't hear the blower motor engage and no air blows. Once I Start driving air starts blowing and its cold but not blowing out as hard as it should when i put it on high. I'm assuming blower motor or possible resistor. I waned to see if anyone encountered this issue before just throwing parts at it. I am in Florida BTW.

The resistor replacement will fix the fan speed. Even though I used a BDW brand here is one that will work well & less expensive!
