if you buy them, make sure they are the upgraded ones. they will have Hummer on the back of the mirror. they are standard with the 06 models on.
they may have to have the wiring spliced to work properly, but do not accept the old ones at all.

also, you can find new-ish mirrors on ebay for $300 ish.

i am having issues with my mirrors, and have been wondering if mirrors from a tahoe/escalade would work? or maybe gutting the motors and rebuilding my old mirrors with them.

i havent taken the morror to inspect the gear motors, but i have also wondered if the parts that are worn down can be fabbed up with more durable parts...
