    Small speakers on either side of center console

    When I had my center console apart on my 01 Yukon Denali, I noticed there were two small (3.5-4"?) speakers in there. I haven't seen these mentioned anywhere. Are they wired to the radio, or for something else?

    00-02 Bose Sub Upgrade

    I'm considering upgrading the rear sub in my Yukon Denali. I know the Bose sub is an oddball shape, so while at the junkyard, I found and grabbed a sub box out of a Tahoe. I'm not looking to push a ton of power/bass, but I'm assuming any kind of an aftermarket sub/amp combo would be better...

    Just finished replacing this about 10 minutes ago lol.

    HVAC Control Head?

    Finally got around to doing this. New (used) actuator took care of it. All good now. Air temp takes FOOORREEVERRR to go from hot to cold, but that will be for another day.

    HVAC Control Head?

    Still working this out, also have a couple other things that sidetracked me. I grabbed two actuators from the junk yard. It's been raining whenever I have time. Hope to get one installed today and give it a try.

    Which Ignition Lock Cylinder

    In case anyone ever wants to go this route....... I replaced the ignition cylinder with an aftermarket one. I'll keep the other key for doors, on the off chance my key fobs don't work. When you look up the ignition cylinders, there will be an option for one with and without accessory...

    HVAC Control Head?

    I'll try that and let you know. Too many threads go without any follow up on a fix. Thanks for the input.

    HVAC Control Head?

    - The one I got was a used one out of an 02 Yukon, same part number as the old one. - Earlier, the only code I had was U1500 - Inter Device Dedicated Bus Malfunction. Checking again after playing around with the tool now sets B0248 - Air Flow Control 3 Circuit. - I haven't replaced any...

    HVAC Control Head?

    Another control head in, does the exact same thing. Actuate the mode door with Tech2, and it sweeps between all 3 levels. Stop the actuator and it goes right back to blowing out of the vents regardless of what the controls are set to.

    HVAC Control Head?

    Sorry, was on vacation for a few days. I'm not getting any DTCs. The fan control and temp both work fine, just the mode knob. Running the actuator via Tech2, it will move, so I know it's not the actuator. Just need to find one in good shape like mine is. Off to a junk yard today, assuming...

    HVAC Control Head?

    Just want to make sure I'm not missing anything here. My HVAC only blows out of the dash vents. When I actuate the mode door with a Tech2, I can get it to sweep from the dash, to the floor, defrost, and back. So I know the actuator works. Seems like the control head would be the issue. I've...

    Which Ignition Lock Cylinder

    I'll call the dealer, see what they want for an ignition cylinder. I usually just use the key fob, so the other key (which is an aftermarket one already) for door lock-only wouldn't be terrible.

    Which Ignition Lock Cylinder

    The lock cylinder seems to be going out on the 01 Yukon Denali I just bought. You have to roll the key around up/down/back/forth, etc until it finally turns. The vehicle only came with one key that is pretty worn down. I was going to replace the lock cylinder and just have two keys, not a big...
