Power Mirror Switch Fix.. replace the faulty surface mount component.
Power mirror switch is easily repaired if you can use a soldering iron, I took mine apart carefully not to break any of the clips , there are 4 surface mount components on the board that is all not over complex at all, 3 of them are black with 000 written on top they are just 0 ohm bridges and dont do anything, so ignore them the other one is coffee color with LF075 written on the top this is a 0.75A resetable fuse that fails , a good one measures 3.2 ohms and a bad one well could measure anything but my faulty one measured almost 35ohms , basically this is the current limiter which is why the mirror may move a little but not much as it wont have enough amps with a the higher value, simply remove the component and replace with a new one and the job is done, just saved you a $150 for a new switch with a $1 surface mount component .
