Rear and Side Mirror Defrost

[jschevy01]

The fuse is not blown, however I still have no defrost on the rear window or the side mirrors. Can something cause the entire circuit to not work. I can't imagine all of them stopped working at once.. Any help would be appriciated

Wow... 27 views and not one idea...I was hoping for better than that...haha

I got out my DMM out last night and started doing some voltage testing. I had power to both connectors to the side mirrors under the molding piece. So I popped out the mirror it's self and I also had power right to the mirrors. So I did some continuity testing and for some reason both mirrors had gone bad... $100.00 for both mirrors and they are operational again. Rear defrost was a fuse.. I am not sure what caused all this.. but all is fixed now...

Have a similar problem on my 01 Silverado. Will check with MM. In addition someone apparently thought I had fold away mirrors and broke drivers side glue joint of Mirror housing to mounting base. Need to find some super strong glue for this. Otherwise everything works fine. Anybody any ideas where to go for some good glue. Live in Manitoba Canada. John

You might want to see if the relay for the defroster under the dash went bad. I kept blowing fuses for the rear defroster everytime I hit the defrost button. I found the relay and took it out. When I put it back in everything worked fine. Like the relay was sticking and blowing the fuse.
