Default dual climate controls not working. heat/Ac

In my 09 c6 base corvette the heat nor the a/c does not come on when I push the control buttons. Any suggestions in how to resolve the problem.

You probably need a new HVAC head unit in the dash.

You could try to find a mechanic who has a code reader capable of reading HVAC trouble codes, like the dealer's Tech 2. That may or may not be successful.

New head units from a dealer are around $450(ish). Forum vendor Cultrag Performance could probably save you $75+. Or you could shop ebay and such, members here have found units for as little as $150, usually used, so be careful.

Thanks a lot. Is this something that usually goes out? The car only has 26000 miles on it. I took the car to a chevy dealership for a headlight recall and to fix a shift turbine speed sensor. Two days after it being out of the shop I noticed the heat or a/c controls wasn't working.

Check fuse box under the hood, especially since they did work on it for the headlight recall.

It is a common failure......BUT......ugh, since you just had it at the dealer for the recall, they may have done something to cause your problem. I suggest you take it back and make them look at it for NO CHARGE.

Yes I will check the fuse box but in between time I will make an appointment with the dealership that did the recall work. Do you know what fuse I should check? Thanks for the Help

Under the lid of the fuse box there is a label showing the fuse locations. On my car the HVAC fuse is # 28. Top left corner if your standing next to the passenger fender. Maybe it is loose or not in the correct position or it is bad.
