hi Another issue with this 2002 crv. The ac just stop working I checked fuses relays under the hood and in the fuse box everything looks good checked the compressor it looks ok check the blower with a 12 volt source and it came on. Could it be the ac switch or is there some other relay that is in the car like the main relay. Does any one have an idea what the problem may be. Thanks

 

a/c pressure switch is bad or check to see if you have pressure in your system first.

 

Thanks I checked the system and it has pressure. If the pressure switch is bad would it cause nothing to work? When I turn on the system not even the blower comes on.

 

If the pressure switch is bad, the cool part does not work, the blower is the fan switch or blower itself may be bad. put some voltage to the blower and see if it turns

 

Thank you I found out the problem it was a ac resistor in the blower box. If that fails the system would shut down and nothing would work. Thanks again for your help

 

good find, thanks for coming back to update. good follow-up
