Where can I find an online diagram of the turn signal switch assembly for a 1995 Cutlass Supreme?

Question

The switch is faulty and I want to clean the contacts for the turn signal switch, but I need to know which ones they are...

Answer 1

You're kinda shootin' in the dark here.
As a general rule, when the switch fails, most often it is cheaper to replace it rather than spend shop time trying to repair it. Mechanics get paid to replace or clean. If they clean it and it fails again, the shop has to eat the time.
All that to say, most illustrations are only going to show the wiring diagram and the connector layout. As far as which contacts are for the turn signals, and which are for headlight dimmer, there really isn't much of a call for that info.
Perhaps you can identify which contacts are for which circuits by reading the diagram, then extrapolate the wire colors for contact position.
In that case, you could go to the library's REFERENCE section and locate the wiring diagram, or buy the repair manual (< $20.00) or perhaps try this site, but it will cost you a subscription, but it is really good stuff. Professional level.
