Heres my problem, About 2 months ago, My power mirror switch failed so I put in my extra one from my parts car and until now it was working great, but now all of a sudden, both of the mirrors stoped working again, Do I need another new switch or is there a secret fuse/relay for it(my repair manual has nothing about the power mirrors).
More than likely you just got another bad switch. Double check all your pins are clean on the connector that goes into the switch as well.
