Passenger side mirror doesn't reset when in reverse

[kimike]

I am having an intermittent problem when I put my 2002 996 in reverse: I have it set up so the passenger side mirror points down when in reverse, however, on occassion the mirror motor will start and then continue after the mirror has gone all the way down. At this point the motor resets several times and then stops. At this point when I put the car in first the mirror doesn't return to its normal driving position. Any ideas on what could be causing this?

This is not 100% consistent which leads me to think there may be a lose wire, but wanted to get input from a broader audience before taking things apart.

Thanks!

Go to 996 DIY section, common repairs, and check this post ''Replacing Reverse Lights/Back-Up Lights Switch''

Thanks for the input. I will look at that, but the issue is not whether it engages, it is that it sometimes doesn't stop. My backup lights are turning on and off as expected. I read the comment in the DIY post but it suggested that the rear mirror was not tilting at all vs. starting to tilt and then continuing to.

Thanks again.

It may still be worth removing the switch and cleaning or replacing, they are not expensive, I seem to remember another post where someone had cleaned a reverse light switch that was not working and after that it worked OK. My mirrors were failing intermitently before they failed completely so it could be similar problem to yours.
