Welcome to the forum from Iowa.

If you could share a little more information about your vehicle like year, trim package, mileage, etc., that will help folks help you.

its a 95 tahoe 2 dr LS ,standard head hvac ..didnt know there was more than 1,175k on truck...350 eng.

Need to do electrical testing. Start with all fuses and relays. Make sure control head is getting power. Do other functions work? Mode doors, blend doors, blower on all speeds, etc?

Could be a bad control head. Gotta test it to know for sure.

ok,fuses are good and the blend doors work..

Ok what else?

Do the lights work if there are any on the control head? Are they buttons that push and click/hold in? Are they just push buttons that light up when you push them?

Pretty sure on that older style they have a little orange light on them that lights up when you push them.
If they aren't coming on then chances are the control head itself is your problem.

1995 was a one-off model, so a 96-99 control panel is not a direct swap unless it includes the adapter.

Here is a thread with some photos, maybe it will help:

Dorman and Delco do make new panels for, last I checked, around $200 or so. Heads up, though, I bought a Dorman and it started smoking within a few minutes. Someone else had the same issue a few days ago on another forum so I’d avoid them. I had no issue with the Delco.

my tahoe is same color,but no flairs..

delco all out of stock..
