    1990 HVAC works when it feels like.

    Hi all, I’ve got a 1990 K3500 I use to plow. All of a sudden, the digital HVAC controller will 9/10 times not turn on with the truck. The back lights are all on, but the screen is black and the buttons do nothing. I checked all the connections behind the glovebox. I removed the unit and...

Really hoping to get this dealt with before the weather gets too cold, has...

    HVAC question

    I have a 1999 k2500 4wd 7.4l base model Suburban. It's fairly new to me even though it only has 51k miles on it. It was originally a military vehicle and then became a sheriff department vehicle, so it was not driven much. Trying to get the a/c up and running. It had the compressor and dryer...

    Weird AC Sound

    I’ve looked on many forums and stuff, can’t find my issue. When I first turn on my truck or turn it off, around the passenger side, around the feet, there’s a horrible noise that sounds like it’s coming from my blower motor. I’ve gotten the blower motor replaced and it still hasn’t fixed the...

    Hey guys, I'm a bit stumped on this one. My heater is currently only blowing warm air out of the vents. I do not appear to have any coolant leaks that I can see inside or outside for starters. My radiator, upper & lower hoses, temp sensor, and thermostat were all replaced in September. The...

    Hello I have a 92 gmc 1500 extra cab. Every since I bought it the heater control stays on all the time. Even with the key off. The fan even stays on. Is this a common problem with the control unit? I haven’t looked too far into it. However at some point this pickup had an after market alarm...
