    2006 denali AC

    From what you've written I'd think (I'm no expert) that the cabin temperature control module needs replacing. On my '04 everything worked except the temp. adjust. But first pull it from the dash and make sure the wiring harness from the back isn't routed over a metal brace and chafed. Good luck...

    Tech2 Expert help needed. Question about HVAC on '04 Denali

    Well ... that was cool. 30 minutes of impressive fireworks from a "city" of 20000 people. I was in Vancouver, B.C. for the Canada Day celebration and it wasn't too much more spectacular. A little longer maybe ... but not better. I think a few people got shot unless my hearing is going. Shotgun...

    Tech2 Expert help needed. Question about HVAC on '04 Denali

    I think he was referring to my question about whether everything runs through the radio. The CANBus system. I want my old truck back. This is tiresome.

    Tech2 Expert help needed. Question about HVAC on '04 Denali

    The manual he sent to me didn't have a bunch of stuff that is on the Denali. It was missing the correct transfer case and some wiring diagrams. Which you wouldn't know till you dug into it. He sent me a generic 2000-2006 Suburban manual. Even though I specifically asked for the Denali manual. I...

    Tech2 Expert help needed. Question about HVAC on '04 Denali

    Thanks James! Did you join them? Have all your hair? ;) I feel sorry for families with little kids where I live. The city fireworks show is on tonight up here but full dark doesn't come till 11:00 p.m. I'm betting there will be some cranky kids tomorrow. IF they manage to stay awake for it...

    Tech2 Expert help needed. Question about HVAC on '04 Denali

    I tried to come at it from a different way last night. Got into HVAC/Data Display/Sensor Data. The Sensor Data screen came up for 1 second then it disappeared and it said "wrong vehicle". So I backed out of the screens to double check I had the correct vehicle. I did. Walked though the screens...

    Tech2 Expert help needed. Question about HVAC on '04 Denali

    I followed the diagnostic steps in the manual and it led me to ... flush the heater core. What?! Which is probably what led the shop I took it to last winter to do the same thing. Who charged me $385 after I told them it had to be an actuator problem. I was choked! If your lines in and out are...

    Tech2 Expert help needed. Question about HVAC on '04 Denali

    I tried a re-calibration first and it "seemed" to work. As in, it changed to the starting temp. then changed from defrost to panel to floor etc. I couldn't hear the actuators moving exactly as it was raining. I think I understand what you mean. You are saying that you have to enter the exact...

    Tech2 Expert help needed. Question about HVAC on '04 Denali

    I'm not good with mine yet. By a long shot! So I need a little help here. I'm not getting heat from my HVAC ... again. When I command the Air inlet door to move (sitting at 6 count) it doesn't. The Mode door goes up in count instead. What am I missing?

    Is buying a Tech 2 worth it?

    Yup. EDIT: They were really responsive to my queries, if in somewhat poor English but better than my Mandarin. I'm sure they would be glad to answer any questions you'd have. Send 'em a question!

    Is buying a Tech 2 worth it?

    Awesome! I should have asked on here ......... :oops: DHL took 2 weeks for me to get mine from China. But it sat in Customs for 5 days. Not bad. It took me three weeks to get stuff from Germany using DHL and the postal system. Apparently they put it on a pack mule across Canada. ;)

    It works on Win7? Geez! I read it would only work on WinXP Pro ... so that's what I put together. *sigh*

    Is buying a Tech 2 worth it?

    I bought mine from aliexpress.com for ?? $400 CDN plus tax and duty. I believe, and I may be wrong, that any of the Tech2's are Chinese manufactured, mine came with all the "correct" decals of Vetronix, they just weren't applied. Which suggests that all come from the original factory but...
