Just curious to know if anyone can locate part numbers for Buick LeSabre'* 00+ side mirrors (just the glass) with heat, turn signal and memory. I am not sure what years the LeSabres had them...but they look to be the same cutout and would probably mount right in place of the Bonnies except for the wiring of the LEDs.

check gmpartsdirect.com they have a few different #* listed.

check under collision, then door, then mirror

Actaully, I did try this but stopped at 04. 03 has them listed...but now I have another question.
They list the signal mirrors but don't specify if they are heated or not. Does anyone know more about these?
#*:
88986209
88986210

the heated mirrors should be standard?

That is MY guess but I know some vehicles can only have either or. If heated mirrors, no turn signal or turn signal with no heated mirrors.

Go on EBay and see if the Lesabres on there have the turn signal mirrors...if they do then check to see if they have the little heated symbol. That is assuming you have a good enough picture to deal with.....
