Envoy with strange Behavior

#1

I have an older neighbor with a 2002 Envoy. When she starts the car up and when she turns it off the mirrors move, and when she turns it off The Horn beeps twice


#2

Is there an after market remote start installed?


#3

YES. There is


#4

Can you disable it and see if things work normally?


#5

Will try to figure it out


#6

I’m pretty sure I heard the mirror moving problem discussed here, or maybe it was on the radio program. Sorry, don’t recall exactly what the cause was though. Try using the search feature above/right maybe to find the thread.

I think you can program that car to recall seat and mirror positions for different drivers, so it may be defaulting to another drivers setting.


#8

Time to break out the owners manual. The mirrors are driver preference, I believe, and it could be something as simple as her hitting the ‘1’ or ‘2’ button for a different driver. I think those also had the mirrors move down when put in reverse-annoying as heck if you’re a temporary driver.
Horn, I don’t know, but again that may be covered in the book.

@OldcarsRbest has the same line of thinking as I do. What trim level is the Envoy? You could also look at the driver door area, there will be buttons for Driver 1/2 if it has the feature…IIRC, the LT has a DIC where you can view and set default preferences. Could still be a problem but this is what I would look into first…
