As soon as I installed my new tow mirrors on my '04 QC 1500 4.7, my right turn signal lamp goes out...then on...then out...then on....you get the picture. I changed bulbs...no luck. It will work for a few miles and will then go out. I pulled my travel trailer home today and the travel trailer's blinkers work fine while the truck doesn't. I'm thinking there is a loose connection in the housing...any other ideas on the problem or how to fix.

 

Would seem not related... There are no turn signal connections in an '04 mirror, right? Heck, disconnect the mirrors an' see if the signal works properly.
