When I turn the AC button on it blinks twice and then shuts off. If I put it on auto, the AC will come on, but only blows hot air. Will not blow cold air at all and heat won't work when it's cold out.

Sounds like the control unit is failing

Thank you for replying. My mother just died and it was her dream car. I want to cherry it out and keep it.

Where can I find it and test or replace it.

I think(I would have to look at my gm service manual to be sure) that its the the actual controls that you use to adjust the system
As far as replacing it that's easy
First tilt the steering wheel to the lowest position and put the truck in 1(hold the brake while doing this)
Second remove the bezel around the dash(I start from the right lower corner)
Third the controls should pop out(check for screws first)
Fourth disconnect the harnesses

Installion is reverse of removal

Ps I will check my gm service manual to be sure that is what has to be replaced for sure.
