I am having a A/C problem on a 1996 chevy suburban. The A/C is not
blowing cold air and compressor is not engaging. I First check
pressure on low side which read zero. I charge the system with the ac
on full and pressure is at 35 with hardly any of the can so I knew the
compressor was not engaging. So I check the accumulator by passenger
side and it gets voltage when I hit the AC button. so then I check the
wire that leads to front of AC compressor by the pully and I dont see
any volatage going to there with everything on. There is also a some
wires going to the backside of the compressor but I did not check
those yet. Any ideas on what to check to see if I can get the AC
clutch to engage. - Thanks for any advice
