Just bought a set of power tow mirrors for my 07 dodge and they are not working. it had the small mirrors and they were working fine so i know its the mirrors and not the truck....any idea what could be wrong with the mirrors?

 

Have checked all fuses? I know on the 2nd gens you really have to route the wires a specific way or you will cut them when you tighten the mirrors down. If everything checks out with fuses and no cut wires, send them back and get another set.
