Question Passenger Mirror adjustment knob - works one way only

The knob (joystick looking thing) in the center console on my wife's 300TE that adjusts the passenger mirror only works to bring the mirror in now. It won't move the mirror out. If I press the glass at the edges I can manually push it out and bring it back electronically to the right position...Not a big deal, but is it the mirror or the switch that need to be replaced? Thanks for your help in advance.

BTW, I searched and did not locate this problem in the database. Some interesting finds though.

I haven't been into the mirror on my MB, but just finished with the power mirror on my Toyota. On the Toy, there are 4 small electric motors turning screws to raise, lower, move right, or move mirror left. The tech told me to hold the switch in each of the 4 positions, while he listened to the mirror. He heard motor noise in each of the 4 positions, and concluded it was not the switch or motors, but the screws. I later pulled the mirror apart, and saw that the plastic worm gear screws were stripped on 2 of the motors.

The MB mirror may be completely different, but listening for the motor noise in each position should be a good starting point. Even if there is only 1 motor in there, noise from each of the 4 positions would indicate the switch and motor(s) are working. No noise brings you back to square one.

At that point you could try a new or used switch (they plug in once the center wood is removed). Or if you are real handy try pulling the switch, making a series of jumpers, and reverse the right/left pins.

If the switch and motors are OK, it is the (unknown-to-me) mechanical drive between the motors and the mirror. Phil in Fastlane may know if mirror parts are available - they weren't on my Toyota. If no parts, a new or used mirror is in the forecast. Good luck.

Mine is flaky too. I can make mine work in about 3 directions if I push the joystick in odd directions. I'm thinking it is probably the 40 or so Dr. Peppers my mother-in-law spilled down the console before I took ownership.
