1992 Cutlass Ciera electrical issues


#1

Main issue: the passenger window no longer works. Thankfully, in a MI winter it died while it was up. The driver’s side mechanism went first, then about a day later, the passenger mechanism went. All of the other automatic windows work fine. Minor issues: turn signals rotate working properly. Manual operation is fine. Speedometer occasionally jumps all over the place. What is going on?


#2

The most common problems for this kind of thing is dirty switch contacts and broken wires in the door jam caused by stress to the wires.
