I need to replace the passenger side mirror, it will not move under power, the nylon actuator going into the motor is broken. It is the one with 2 arms, a large mirror and a small convex mirror at the bottom. They are power mirrors, but not heated. I am having trouble finding replacements. They all seem to be heated, and I also don't know what type of connector I have since I have not completely removed the old one until I had a replacement in hand..Some have round connectors and some have square ones. They don't seem to "telescope" but they look like telescope mirrors. Can anybody steer me in the right direction? '99 F250 SD XLT 7.3.
