Tire pressure sensors stopped working with low pressure light on and key fobs stopped working at the same time. Could this be related somehow, going out at the same time? Had trouble with power to my rearview mirror after a windshield replacement and found a blowen fuse, happened around the same time.

Could be a blown fuse, a loose relay, a loose ground wire. Try tightening the under hood fuse box bolts, there are 4 of them 7 mm heads, then push all the fuses and relays firmly into position, same for the fuse panel on the passenger side of the console.

Yes, related. Check the BCM fuses. #23 RDO. The RCDLR is the radio receiver for both, it lives under the headliner behind the rear view mirror. The installer may have disturbed it.
Figure out why the fuses blow or start a fire.

How do you get to the RCDLR under the headliner?

donbrew

By pulling the headliner down.

They look a little pricey. I might find one in a you pull it yard. Does it still need programed by dealer?

donbrew

I doubt the RCDLR is brokem, much more likely a wire got shorted and blew the fuse. They do need to be programmed to the fob, the TPMs can be reset usung the procedure in the Owner Manual.

Number 23 fuse was good maybe I already changed it. Didn't happen at the time windshield replacement.

Try a battery lobotomy, disconnect the negative terminal for a few minutes, then reconnect, this should reset the computers .

Jim's 2009

I did try that.
