That fuse is for OnStar/XM radio and RCDLR.
The AP3 formerly was for remote start, but the definition changes from list to list I see, it confuses me.
The RCDLR is smaller than a 2.5" laptop hard drive. It and the radio antenna amp are under there.
If the tire pressure displays the RCDLR is in the car. It is the receiver for the TPM as well as the Remote fob. The problem is finding someone that has the right tool and how to use it. The easy thing would be to go to a GM Service Department, some of them are reasonable.

Fob only has lock, unlock & horn buttons. What about AP3 on the glove box door? Never mind that somehow I missed your reply to that. Might price some dealers, but they were sure high cost when I used them for the 87 s10 we had.

Can you clarify what you mean by this? Sounds like the front and rear sensors are switched(why you need calibration) and you need 2 new sensors.
