Asked by carguy598Answer
no, it is a separate system. have the freon pressures checked.

I personally charged to proper level of freon and compressor will not engage.
how much did you install?? what were the pressures when you jump the compressor??
Roy
evacuated system, vac for 35 mins, added 24oz, spec is 22 to 24.7. pressures were 35 low, didnt have high side guage hooked up though
it appears that when the switch is turned on, there is not power going to compressor, continuity between relay box and compressor is good, fuse is good.
Have you tried to bypass the clutch cycle switch?
I did bypass the cycle switch.. still made no difference.
it appears that after further diagnostics, there is a self diagnostics through the control head, if there are any codes it will tell the pcm not to engage compressor. I ran self diagnosticcs and it had blower speed fault. went through testing and found out that resistor is causing blower speed fault. will have the part in 3 days, will update when part comes in if that resolved my issue. thank you to all who responded and tried to help me through this.
UPDATE ON REPAIRS: I replaced blower motor resistor, went through self diagnostics again as directed by trouble shooter. started vehicle and turned on air. works great! 31 degree drop at center vent!
