My '02 wing mirrors stopped functioning. I suspected a fuse (#35 in the drivers leftside kneehole panel) since neither mirror worked but it was fine. Tested for 12 volts at the mirror switch by prying up the trim, unplugging the heated seat harnesses, then the two harnesses to the mirror switch. The color code is green/red (+12) and brown (gnd) on pins 1&2 of the black connector. Tested good 12 volts when the ign switch is in pos 2 (ON, not accessory). Suspecting a bad switch and seeing my $ fly away, I removed it (by removing the heated seat switches first (#6 torx required). The switch is NOT just a switch, of course, since this is a MINI afterall. Nope, it has 2 integrated circuits on a circuit board that also has the actual switch contacts. Thinking the worst but hoping that cleaning contacts would work, I buffed the switch contacts with metal polish. Reassembled and tested. That fixed it! Another bullet dodged. Now if I could just repair the boot latch...
