Hello all. i wanted to tell you all a quick fix for the issue on the 2003 Silverado rear view mirrors when all of the digits light up at once.

I recently took my truck to get the windows tinted, (only cost $150!!) and the guys who took the mirror apart to put the tint strip on my windshield found that there is a little module inside the mirror base, (where it screws onto the window mount) that had some dirty connections. when they put the mirror back together and fiddled with the module trying to find where it mounted, the mirror starting working again and hasnt given me any issues. im really glad since i was literally going to buy an new mirror that day! So, if i were you, take your mirror apart and check the wires, putting some dielectric grease in the connections.
