[s-cars] A/C problems revisited

[George Verbryck]

Well to day I had some time to play with the A/C on my car and found that the codes remained after I cleared them via the ECU fuse. On channel 53 in the climate control I am getting a1. slippage or blockage , A/C refrigerant high pressure switch, 120x off. Also a sporadic f2 ( i.e. little segment flashes ) A/C refrigerant high pressure switch. The climate control worked today if I had not checked the codes would not have known there was a problem. So I suspect the high pressure switch , however I could not find the switch. I know where the low pressure switch is on the fire wall but where is f118? Also how do I test it? Does it have a valve like the low pressure so you can remove it without letting the freon out? I am also getting a few other codes under channel 1, 11.5 central flap static block, I assume this is one of those little servo motors I have heard so much about on this list ? 15.1 air flap motor potentiometer static open , are these related or
 separate problems? 29.4 belt slip detection hard sporadic, if the high pressure switch is faulty could it cause this belt slip ? I have decided to replace the serpentine belt as it has not been replaced since I have owned the but indicated records show less than 30,000 miles since changed, but you never know it will also give me a opportunity to free wheel all the belt driven devices . Any help would be greatly appreciated , Regards, George
