Please help! I'm trying to learn as much as I can while troubleshooting why my A/C doesn't blow cold.
Symptoms/notes:
A/C light does come on when I push the button in. However, clutch does NOT engage (that would explain the warm air output, huh?)
Fuses are good both outside and inside.
I have read a lot of posts and watched at least 2 hours of youtube video (I'm now an expert, right???)
Pressure is 25psi on low side when the engine is off or at idle (Probably due to clutch not engaging). Cannot read the high side yet (working on it). I shorted across what I thought was the low side switch - connected to the evap/collector/can next to firewall. Clutch engaged! So, I thought, I must have a bad low side switch. However, I go to my friendly NAPA and they show me a picture of the low side safety switch and it doesn't look like what I crossed. What I crossed, according to his computer, was the compressor clutch cycler (huh?). This is where I need your help.
Did I cross something other than the low side switch?
If I did cross the right switch (remember the clutch came on), should I proceed with replacing that switch as a less expensive first step?
If I do replace the switch, can I unscrew it from the side of the evap/collector/can next to firewall without recharing the system?
I would appreciate any help any of you could provide. As a note, I'm really enjoying troubleshooting this issue. I hope I can fix it myself.
