Both Mirrors Do Not Operate

WARNING: This page is about a different car, the 1998 Oldsmobile Aurora and 1998 Buick Riviera. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect power mirror switch connector. Connect test light between power mirror switch harness connector terminal "A" (Orange wire) and ground. If test light illuminates, go to next step. If test light does not illuminate, repair open in Orange wire between power mirror switch and right rear junction block (located under left side of rear seat).
  2. Connect test light between power mirror switch harness connector terminals "A" (Orange wire) and "J" (Black wire). If test light illuminates, check for poor connections at power mirror switch. If connections are okay, replace power mirror switch. If test light does not illuminate, repair open in Black wire between power mirror switch and ground.
