I finally got a chance to get under the dash and give this matter the attention it needs. I started trying to chase the wires but quickly found out it was going to be impossible without cutting down all this crap. I guess that's why I didn't screw with it 6 yrs ago. I got enough pulled down to check the voltage on all the tapped wires, and discovered there was no power to the secondary ignition circuit from the control head in the "run" position. Further wire chasing found a bank of 5 in-line, blade fuse taped together and tucked down behind the kick panel. Any guesses what I found next ? lol............a blown fuse to the secondary ignition circuit. Why in the hell would anyone tuck those fuses behind the kick panel ?!?!?!?!?!?!?!?! And to make it worse, you couldn't tell any wires were routed in there unless you pulled down all the rest of the crap. Anyway, I changed the fuse, tested the circuit, then tested the remote start system several times. It works GREAT. Not sure why the fuse was blown...I didn't see any obvious cut or chafed wires. But I guess if it blows again, I'll have to pull out the entire system and see if I can find something. In the meantime, I'm going to enjoy getting into a cool truck again. lol THX for the help !!!!!!!!!!!!!!!

 

I guess I jinxed myself. Everything worked great for 2 days this week. Remote started the truck on Wednesday about 10 minutes before coming out of the shop to go home. Opened the driver's door and noticed I didn't get hit my now common rush of cool air. Got in, looked around, felt warm air coming from my dash vents, BUT my EATC controls were engaged and it showed the unit was set on "max air". Hmmmm. Before I started to seriously lose my shot (thinking something was now wrong with my AC), I decide to turn the key to the run position. Surprisingly, the AC engaged, and worked flawlessly for the trip home. When I got home, I shut off the truck, but stayed inside the cab, and remote started it. Sure enough, no AC engaged, despite what the EATC controls say.

This weekend, I got the chance to climb back under the dash. Thank goodness I didn't get a chance to "properly" zip tie up everything last weekend. Anyway, all the fuses are good, and as far as I can tell, all the wires appear to be intact. It's IMPOSSIBLE to be under the dash and use the remote start to troubleshoot. I'm way too fat to try that "stretch Armstrong" crap, upside down, with the door closed. lol. I'm assuming there's some type of "broken circuit" between the EATC control head, and the actual AC compressor...but damned if I know where to start looking. Like I said, the EATC stays lit up, and says the max air is engaged. The fan is running on high, however, the compressor will not engage until I turn on the ignition. Oh well, I thoroughly enjoyed my 2 days of having a cool when I came out from work. BUT, the more important thing is that atleast I think I have heat now. I can certainly deal with the hot truck, a helluva lot better than an ice cold truck in the sub feezing mornings to come. lol.
