I have a 2023 Suburban and I am having the following problems: windows will not open or close, mirrors will not open or close, doors will not lock, driver's seat programming not working, maybe more that I haven't noticed yet. There was a message on the screen that said: "Service door lock system". First time it happened I just parked in my garage and the next day everything worked. On another day it did it again and I parked and came back about 20 minutes later, and everything worked. Anyone else having this problem?

 

Are you still under warranty? Take it to the dealer.

 

I have an appointment at the dealer service dept. I was just wondering if anyone knew what the problem is.

 

Sounds like a loose connection, maybe a loose ground somewhere.

 

Wow! How could you find something like that?

 

measuring and diagnostic tools, schematics, diagrams, training ...
