I'll admit... I am not much of a HVAC guy. I know just enough about it to get me by but that's about it. I'll get to my problem. My truck has had a history of frying PCMs and yesterday I found out why. The metal hose on the high pressure side of the AC drips water when the AC has been running. The water would collect on a grommet that holds the line to the body and drip onto the wiring harness right as it goes into the PCM. I have done extensive testing and research, as have a few other mechanics in the area, to find out why my truck has been frying every PCM that has ever been put on it. And yesterday I "accidentally" discovered the cause of all these fried PCMs while putting freon in my truck and looking around at the AC lines.
My question is, is this just normal condensation dripping from the line or is it a leak?
