I bought a set of the 2006 towing mirrors for my 2004.5 LLY CC GMC Sierra LT to replace the regular power mirrors with turn signals. They bolted right on, plugged in and everything worked. When I started driving it I noticed that sometimes when the engine is turned off and/or started that the mirrors would go out and up and leave me looking off into space. I set the "driver 1" setting on the armrest/door but it keeps happening. If I press "driver 1" it doesn't go to the preset position. I got my manual out and studied it, thinking that maybe I missed something about how to set it but I didn't see anything new. I have not been able to detect a pattern or particular event that makes it happen, seems like a random thing when turning off and/or starting the engine.
Anybody else seen or experienced this? Is there a flash update I need to get for the different mirrors?
