what does it mean, aside from the obvious :lol: I 'm trying to figure out what may have caused this. Last thing major that happened before this code showed up, my E-Fan's stopped in the middle of driving. I pull the harness to check it and the 1st Relay is FRIED. Wonder if this has anything to do with the PCM??? I also noticed that my so called ground wire(green/white) for the A/C is acting a little wierd...when I hook it up to the connector for the wiring Harness it turns the fan on while the A/C is off!!!!!...When the A/C is ON, it will turn the fan back off???!!!!??? Also wierd the fan will run when the truck is off when its plugged into the A/C wire!!! Once I take it off the A/C wire it shuts off any suggestions?? Is it possible to Put the A/C wiring harness on backwards on the A/C side itself??
