Ok, I need guidance. I just noticed that I cannot adjust my side mirrors, left or right, from the bottons inside the cab. I am switching the toggle from left to right, not leaving it in the neutral position.

I cannot decern if the mirror heaters are working.

Is there a fuse which may have gone bad, if so where is the little bugger?

Any other ideas would be greatly appreciated.

I did have the deck changed, but that was two months ago, but I don't recalladjusting the mirrors after that time.The installer used the the can bus wiring harness to replace the factory deck and everything else appears to be working fine.

Any ideas on where to start?
