    Key stuck in ignition(Accessory Position) & other ramblings

    Hey y'all! It's been quite some time since I've visited here and I still own my failblazer (2004) haha After I moved to Montana 12 months ago, my key got stuck in accessory mode. I found the easiest solution was to remove the plastic shroud from around the steering column so I could...

    HVAC problems

    I was planning on replacing that wire today. Came up with an idea. Before I did anything, I pulled on the orange wire to in connector and retested voltage. It now shows 12v and all functions are working on ac unit. Guess it was a loose wire after all =)

    I so want to facepalm right now haha! So basically you're telling me to rip up all the carpet and then go from there? I want to be as non intrusive as possible *( if that's even possible )* Thanks for the help )) Please tell me that I don't have to do anything too crazy. Again, though, if a...

    HVAC problems

    If I verified there's no voltage at the HVAC head but there is at fuse box, I would assume there's no continuity when I test from test point at HVAC head to fuse box. There could be a short but I don't have any tools to test if / where the short might be. The rear fuse box goes straight under...

    You are correct, budwich. I don’t think this is something I can do so I’ll check with local shops and see if they are even willing to run a new line without charging a ‘diagnostic fee’. I’ll find out tomorrow.

    Ok there’s 12v at the fuses and underside where 3 orange connectors meet fuse box there is 12v. Behind the connector to hvac head the orange wire is spread. But I think this was caused when I kept popping power probe and t-pin in it.

    So to access the fuse blades, the fuse box will need to be disassembled? Is there is a guide for this?

    HVAC problems

    I'm so ecstatic!! I finally found the problem to my hvac dilemma. So guess what?? It was the orange wire on the blue connector connecting to the hvac unit. It wasn't actuators, nor the hvac unit itself. When I was testing the fuses in the rear fuse box I had the light probe connected to positive...

    HVAC problems

    Got up this morning and had some tasty espresso. I was thinking about what else could be causing this hvac system to fail. I went over to rear fuse box and found that the hvac b fuse does not light up whether I'm in accessory mode, engine running, or car completely turned off. Tried another fuse...

    Changed out the 'mode' actuator today. It was a bitch getting the darn actuator out without removing the pedals and floor duct. Reset the hvac fuse. Didn't hear the actuator make any sounds nor did it make any movements. It dawned on me that I could have tested these actuators before buying new...

    HVAC problems

    I sent back the control unit today for an exchange simply because the ebay seller said everything was testing and working yet the lights did not work. So I'm getting a different used replacement unit mailed from them. As you mentioned @Mooseman, prior to this, changing the control unit will...

    Replaced blower resistor pack and fan speed 5 works again :2thumbsup: Thanks guys! Credit goes to all of you! Last issue to resolve is the HVAC mode controls ( directional fan control, / a/c engage, re-circulation engage ) So the replacement control head I bought awhile back has issues with the...

    HVAC problems

    Tonight, I pulled all the HVAC fuses in the 2nd fuse box and waited at least one minute. Turned key to accessory. Immediately heard a noise that continued until I removed the key. The noise sounded like it originated from below glove box. Not sure if it was whirring or buzzing. Hard to describe...
