Hello All,
I just bought a 2012 Suburban LTZ. The heated steering wheel isn’t working correctly. The button wouldn’t light when pressed and no heat on the wheel.

I check fuse #48 and it’s good. Next I found the 7.5amp inline fuse under the dash, which was good too. After that I turned the key to accessory and the heated steering wheel functioned properly. However, when I turned the engine on the heated steering wheel stopped working. Even if I tried it with engine off the button again it still wouldn’t work.

I pulled the 7.5 amp fuse and reinserted it and once again the heated steering wheel functioned until I turned the engine on.

Does anyone have any suggestions on how to fix this? Thanks.

 

I just started having the same exact issue. When the key is turned to accessory, heated steering wheel light comes on and everything begins heating up on my 2013 Avalanche. As soon as I turn the engine on, everything goes dark and won't work at all.

 

Any luck finding out what was causing this? Having the same issue.
