Need help with advice on adding steering wheel heat to a 2020 blazer. I thought I can just buy the wheel and clock spring (lots of videos about this on similar GM vehicles on YouTube). The issue seems to be getting the steering wheel from GM…THEY WON'T SELL IT! I have a 2020 3LT blazer. The Premier level blazer (without adaptive cruise) is the correct wheel I need. P/N is 84734145. Any suggestions? Anyone know a Chevy parts guru who might know that a different wheel will work...or how to get the one I need?

I'm surprised that GM won't sell a new steering wheel. Maybe it's a liability thing. Might have to find a donor car that has the right wheel you're looking for.

@Flyboy I think you will discover that automakers are getting stricter on what you can do to your vehicle. Almost to a point that all we're able to do is regular maintenance and depend on aftermarket that can still be done.

Other than a donor car, you can try an independent shop that specializes in GM vehicles.

Nope. They accept the order then cancel the order saying it cannot be obtained...

The correct part numbers for adding heated steering wheel are 84922940 for the wheel and 39136243 for the clock spring. After much research, it looks like I just have to wait for GM to make the part available for aftermarket purchase. Maybe 2 mo, maybe a LOT longer... But it will be worth the wait when it happens!

Well... I got the heated steering wheel and upgraded it (including the clock spring). All the wires are present, including the fuse. Unfortunately, it isn't working yet...probably because of the BCM programming. Does anyone have a contact that might be able to help?

Mission accomplished (finally)! It wasn't easy, but I did get it done and the result is WONDERFUL in the cold!

Here's what I did to upgrade my 2020 Chevy Blazer 3LT to add a heated steering wheel:

1) Purchase & Install heated steering wheel (84922940) $228 and clock spring (39136243) $51

2) Purchase 2 GM OEM "pigtails" pinned wires (13575867) $10 each to plug into the back of the clock spring connector for heated steering power (PIN #21) & ground (PIN #8)

3) this is the hard part Replace the 7-wire heated steering wheel module inside the steering wheel with a 6-wire, non-lin computer version. I used (23121936 Steering Wheel Heat Control Module OEM GM 2015-19 Cadillac Escalade) that I found on ebay new for $30. The only hard part was removing the existing 7 wires from the current module and soldering 6 of them (ignoring the lin line) into the new "non-lin" module I bought.

4) Wire the power and ground wires through to the existing heated steering wheel fuse location in the fuse block.

5) ENJOY THE HEAT!!!
