I have a 98 buick park avenue, the a/c compressor is not working,but if I jump the compressor clutch relay wire at the computer the compressor kicks in and it blows cold air.
I'm getting no voltage at the a/c pressure sensor signal wire(red} I repaced the a/c pressure sensor,still no signal,what could be the problem. I have some history codes P0113, P1111, P1604, P1639 and P1641.
