Air Conditioning problem
V8 two wheel drive automatic 195,000 miles.
When I hook up the gauges low was 95 and high was 75. I jumped the compressor to the battery, engaged the compressor, and the low went to 30 and high went to 150. So, I started checking the electrical. The relay does not engage. So, I jumped 87 to 30 connector and the compressor engaged. So, I checked 86 and 85 connectors no power on either. I jumped the pressure switch on the accumulator and nothing. So, I tried to jump the other switch on high side of the compressor still no luck. I cannot find a electrical diagram (even in the Haynes book). Oh, I checked all fuses as well.
Help, what powers the relay to close?
Does the pressure seem right. The low is double when the compressor is not on and then balances out correctly when the compressor is running?
have the same problem?
