2002 Oldsmobile Bravada wipers, windshield & visibility problems

Both remote mirrors will not hold their memory. I have had my vehicle into service for this problem four times and the problem still exist. The mirrors move when the key is inserted into the ignition before starting the car. Also, both mirrors will not hold their position after being programed in either the normal driving mode or the "reverse-backing up" (curb view assist) mode. I have to manually move my mirrors each time I get into my car to drive, even if only leaving it for a few moments.

Dt*: the contact stated while the vehicle was at the car wash in 2003 there was a water leak on the passenger side. The right power window would not rollup or down and this occurred intermittently. The dealership could not duplicate the problem. Two-three weeks ago while trying to get the window to roll down, the engine died suddenly without warning. This was the third time the engine died suddenly. The first was while driving 60 MPH on a dry highway.
