To Whom Might Shed Light On My Issue,
I apologize ahead of time if this has been covered elsewhere. I have scoured the internet and this forum specifically to locate any possible fixes.
I have a 2006 LBZ CCSB with the AUTO HVAC, GMT800 with CJ2 package I believe, that has no power to the HVAC head unit. There is hot/warm air coming from the center front and rear vents and outside air coming from the passenger side vents if set to open.
So far I've triple checked all the fuses and relays, both under hood and dash. I've purchased and replaced the "blower control module/resistor" under passenger side foot well. Removed and replaced the heater control unit with a friends from his 2006 gasser which had the exact same symptoms installed in my truck, however mine worked in his truck, therefor leading me to believe that my head unit is still good. There is positive ground and 12V seen at the black and red wires to the blower motor module. I have illumination lights on the control unit but no digital display or reaction from any of the buttons.
This has been an ongoing issue for a couple months now and it's just getting too hot to maintain anymore.
I'm very capable mechanically and would rather not take my truck to a "professional." Without a tech 2 I'm at a loss for where to go next. Any ideas, suggestions, or opinions would be greatly appreciated. Thanks in advance.
As a side note I've recently removed my entire Banks setup in anticipation of selling it for an EFIlive gig.
