Hey so I got a 2005 Chevy Tahoe & I just replaced the speakers the other day. When I got home I tried locking the truck to find out that it wasnt locking or unlocking at all I thought it was my key fob so I tried the locks on the door & nothing. My windows wont go up or down. The doors will not lock or unlock. when I Put the truck in park it starts to make lock clicking sounds but thats it. And also got a “TIRE SERVICE MONITO” message on my cluster. Can anybody help me out

 

Welcome to the forum. You need to post your question in the Tahoe section of the forum where you will get more views. This is the Welcome New Members section.

My first thought would be that in replacing the speakers, you somehow managed to disturb some essential wiring.

 

All of those systems I believe runs through the rear lift gate my 2007 envoy had this issue and I had loos wires behind the cover on the rear door

 

Sounds to me like something is disconnected or shorted - possibly in the driver's door, since all the window and door locks go through the driver's door master panel. I assume you replaced the speakers in the driver's door, and since that involves pulling the door panel, and disconnecting the wiring harness to the switches, that is the first place I would look.
