Newb with ?'s

[maddawg]

But i did do a quick search first but it didn't or "I" couldn't find the answers i needed. I picked up a 2013 Tahoe today and can't for the life of me get the AC to turn on. I push the button and get 3 flashing lights and off it goes no cold air just 60 degree fan blowing!!! Any help on this would be greatly appreciated.

Next question i have is what kind of harness do i need to keep all steering controls and maybe even the controls for the buttons on rear of the center console? Radio wise? I have the basic xm radio i want to add a aftermarket DVD/NAV system. Trying to find a harness is this the one ?

If the outside temp is below a certain degree the ac will not engage. Don't ask me why but GM made it that way

man if just blows "cool" air the snow flake never stays lit. I've been going nuts i hope it's what you are saying because this is my first Chevy lol no ac on day 1

whats the temp outside? I think its anything below 35 degrees it wont engage. There are a few other reasons it wont engauge. Refegerant pressure to high or to low, battery voltage to low, engine not running. You can test it. To test, turn the AC on. Press and hold the AC button at the same time as you press and hold the recirculate button. Hold for 5 to 8 seconds. That should make the compressor come on. The info is also in the owners manual if i didnt say it right.

I will check the manual but i just tried what you said and it never kicked on i did just realize if i don't hit rear those jokers will get no air (fan in my case) or heat

I have a 2010 and 2012 Tahoe. That's what it is. Below a certain temp when you hit the A/C button it will flash a few times and you will only get the fan. Same on my last 2 Trailblazer SS's. Don't worry.

outside temp?
