When i hit unlock on factory keyless entry my passenger side mirror tilts down? any ideas?

have the dealer reprogram the power mirror-window my mirror would not tilt in reverse they reprogramed it in 10 minutes all fixed:D

Have you tried to reprogram your seat and mirror settings?? Set everything where you want it, and hold down the "1" or the "2" (whichever remote you are using) until it beeps twice *pretty sure it's two beeps*. Move everything around, push the unlock on the keyfob and see what happens.

Its the memory position you have set for that remote and that mirror. Set the mirror where you want it and resave the position for that remote - directions are in the owners manual for the truck.
