Hi from Indiana 2003 Chevy Silverado

[davight87]

Hello everybody. I'm new to forums so bear with me. I have a 2003 silverado 1500 extended cab 4x4 with 5.3 engine. I'm having problems with the inside rear view mirror. It is the one that has "passenger air bag" and 2 buttons underneath then has the compass/temperature display. I have found other forums with mirror display issues but haven't found any with my symptoms. Every time I start the truck the compass/temperature display will work fine for a few minutes then the display will go off. It seems to make a difference whether the sun is shining hot or not, because it will stay on longer when its cooler outside. When the engine is running and the display is off, if I reach up and unplug it then plug it back in it will come on and stay on for a minute then go back off. If I shut off the engine then restart, the display will always come back on for a minute then go back off. I have already gone to the junk yard and got another mirror hoping it would be a good one. It is some better than the old one but still doing the same thing. Enough so that I am wondering if something else could be the problem or if I am now the proud owner of 2 bad mirrors or if I should try a 3rd one? The auto dimming feature seems to be working like its supposed to all the time.Thanks in advance for any help you can give me.
