I just bought a 2002 Olds Bravada with 20,000 miles on it. Problem:
When I get in to drive the automatic mirrors usually go to some
position other than the one I programmed with the driver 1 and 2
buttons. Sometimes I don't notice until I am on an on ramp pulling
into high speed traffic. Then it's a race to click to the passengers
mirror and twiddle the knob to adjust while I listen to squealing
brakes and watch obscene jestures.
I removed the reverse curb look feature to keep the mirrors from
looking down as I backed up thinking that was too much of an
adjustment for the computer to contend with. That may have helped but
only very slightly.
I went to the dealer. The service writer told me that the wavey lines
on the outside mirrors are sensors that adjust the mirrors for bright
lights from the rear. Well I didn't just fall off the turnip truck.
Those mirrors are electrochromic and do not hcange positions for
bright lights. The wavey lines are just to signify the mirrors are
heated. They do have a computer that controlls them to reposition
them for each programmed driver.
Anybody else with the same problew with their Trailblazer, Yukon (I
think) or Bravada? Anybody had the problems fixed?
