I jump the #5 &#7 the compressor came on & the a/c is working fine & there is not any rpm discrepecency.
1.This car does not have copper in 12 pin socket it means there is not ant hot temp switch.
2.I checked trotle switch circut by using positive battery terminal & pin 4, no voltage.
3 Checked the compressor speed sensor I got 650 resistance & .3v ac at idle.
4. Checked the engine speed sensor got 7v ac but voltage did not increase with engine rpm increase.
5. Might be klima relay bad.
Can I jump the #5 & # 7 in the relay & put the relay back in the socket & run for a while because I am just by passing the sensors.
