Right Mirror Does Not Operate In Up/Down Positions
WARNING: This page is about a different car, the 1998 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
Check for open in Purple/White wire between power mirror switch connector terminal "F" and right power mirror connector terminal "C". Check for open in Yellow wire between right power mirror connector terminal "D" and splice S502 (located in left front door harness). Repair as necessary. If circuits are okay, replace right power mirror.
