Shifty Mirrors

[05alive]

Thanks guys so much. I may end up unplugging them, I am going to look into manual mirrors as well. I don't know yet. I know this behavior is not normal. I have tried to isolate it but I cannot find any good schematics or layouts. I am thinking that there must be a connector or a wire running from them sending the memory output to them.

The mirrors are dumb. They just get input for up/down/left/right/fold. Cutting wires is going render your mirrors inoperable.

Your memory functions off the key fobs and not your keys. When I start mine it tells me in the DIC which fob is being used and sets the car to memory setting for that fob.

The mirrors are dumb. They just get input for up/down/left/right/fold. Cutting wires is going render your mirrors inoperable.

So, when they are adjusted to a certain position, how is this position sensed and programmed so that they move to this position as set by the Driver #1 and #2 memories? Surely there's something like a Hall effect sensor and counter or (more likely) a varistor inside the mirror adjuster assembly reporting back to a controller somewhere, requiring wiring additional to the motor drive wiring. You are correct in saying that the mirrors receive a simple analog voltage input from the switches to operate the motor drives. But, there has to be a controller somewhere that powers those analog circuits in parallel to the manual switches. If this module is located remotely from the switches and is on independent parallel circuits, then the wires can be cut/module unplugged. Chances are that the manual switch circuits feed directly into this module before ultimately ending up at the mirrors. Hell, that "module" may be built into the switch assembly and consists of solid-state circuits that can't be cut/bypassed so easily. Although, if the module doesn't know where the mirrors are (by cutting the sensor circuits from the mirrors that report to the module), maybe it would default to not trying to move them at all and the regular electric-adjust functions still operate. Yet, if the module is in fact built into the switch assembly, then the OP could try simply swapping out the switch assembly with a known good one to determine if his is just faulty and the repair would be quick and easy and he's retain all of the functions.

I really, really wish I could find the right wire lol. If anyone knows I would much appreciate it.

They are different. I have a 2005XL - LUV the body style...chrome, steel, glass...not all plastic. Held the #1 button. beep beep. Then moved the seat way forward. Got out, locked the car. Then hit the unlock on the fob = NO CHANGE in the seat til I got in, and hit the #1 button... THEN back to the original position.

Agreed. Nothing linked to keys or fobs until 2007+

I am going to try to reset everything if I can, this mirror thing is driving us nuts. I am wondering if that blue connector is part of the memory, or it might have been the black one. I am going to take the door panel off and try unplugging mirror stuff to see if I can stop these from moving on their own.
