    02 Yukon Denali Ac issue.

    So I watched the heater treater video for the yukon and Im convinced that blend door isnt broke.With the acuator off I can turn the blend door and get really hot air to come out and back to get cool(not cold)air.So it seems the door is intact.

    02 Yukon Denali Ac issue.

    What blend door should I bee looking at? The one I checked it the lower main. But from what I understand there is more. Also it's not dual zone...if that matters.

    02 Yukon Denali Ac issue.

    So little update on the blend door actuator. I got a brand new one and plugged it in before installing it and when I turned the temp knob...it did nothing. Side note I turned the blend door by hand to see if the air gets cooler...it didnt.

    Update/New Problem/Question

    So I posted awhile back about my 02 yukon denali having a whining/howling sound on take off. Well I found out that whoever had the truck before me needed to replace the front diff and when they did so they did so with a 4x4 front diff and not an AWD front diff. So the diff isnt engaged due to...
