Recharge

first thing is you need to see if the compressor tunrs on when you put the a/c on.. ( you can tell if it's on by the clutch spins with the pulley)

if it does not activate the clutch when you turn the a/c on, then most likely it's low on freeon and you have a leak. the system protects itself by not allowing the compressor to operate with low freeon..

if you want you can jump the a/c cycling switch ( located on the low side near the acculator) with the stichd jumped you can see if the a/c gets cold.. but be carefull when doing this because you can freeze the evap core or do damage to the compressor.

to be honest A/C work is best left to pro's most backyard guys don't have the equipment for testing and recovery and recharging that we have, plus modern A/C systems are tied into the PCM and the one on our cars uses the CCRM ( constant control relay module) to control the cycling of the A/C

I dont wanna take over someones tread, but I notice that someone said that the a/c system protects itself when it is low on refrig. Well about a month ago I notice my ac was got cold/warm/cold/warm and now its warm all the time. I took it to a local shop to get my system rechared (I figured it was low on refrig.) and they said the my compressor was bad because the clutch would not stay engauged, and gave me a quote of about $700 to fix it....could it be engauged and disengauging because it is low?

Thanks
