Recycling the ignition switch may bring the control head back to normal operation. Not sure if it helps or not yet. After polishing the Control Head terminals, but before reconnecting, check for proper terminal contact as described in the applicable electrical diagnosis manual. Well, I went back down there with a live wire and touched the contacts. If I take the battery cable off and reset the computer it will work great for another few days. Have to at least know how to test relay, if you do find it. In addition, it measures the duration of the time the compressor is engaged.
Posted on Apr 21, 2009 There isn't a camshaft sensor. I simply used fine fine sandpaper. Showing parts 1 through 10 below. Any ideas on what is causing this system to do this? I am suspecting a blower motor is pulling too much current although not enough to blow a fuse. I would check the pick up coil and control module. These are a few Service Bulletins I found that might help. I investigated the relays I am assuming each one is for a different blower speed and pulled them open.

The controller monitors the state of the low pressure cycling switch if the compressor has been activated. That engine had 200K miles on it. Performing this procedure, in many cases will make replacing the Control Head unnecessary. I am currently waiting for a new plug from my local dealer but I have bypassed the connector and manually connected the wires until the dealer gets the connector get it.

Hello I have a 1991 Chevy C 1500 truck 5.
Posted on Jan 25, 2009 You can try this, I had the same prob. If the compressor is engaged for less than 1. My main problem is that my heater blower will not blow in any of the two lower speeds, and when I try to select the high speed, the relays start rattling and the Climate Control screen starts to flicker, then resets itself to a default setting floor vents, mid temp, low fan. I just know everytime it has quit, I had it in recirc mode. That engine had 200K miles on it. My connector was so overheated that the large red wire melted out of the connector.
Plug it back in and try it. I am suspecting a blower motor is pulling too much current although not enough to blow a fuse. You never change parts until you know their bad.
