Ok, I have a real head-scratcher. The case of the annoying GM ghost wipers...
I have a 1970 Pontiac Catalina wagon – 400 V8, 3-speed manual. It runs great. Nice car. But there seem to be a few electrical demons.
1. The wipers sometimes come on automatically (even though they will not come on when I flip the switch, because there is no fuse installed in the WIPER slot on the fuse block.
2. The car sometimes will not start. By that, I mean I turn the key and nothing happens. So I put it in neutral and use a screwdriver to bridge the terminals on the starter. The key usually makes the starter work after that.
3. The radio doesn't work. Who knows why, and it's not important, but maybe it is important. Just thought I'd note that.
4. The horn buttons seem corroded. The left one works if you fiddle with it, but not the right.
5. The rear window dash switch (the one that rolls the rear window up and down so you can open the rear hatch) worked when last spring, but doesn't work anymore.
Everthing else – turn signals, lights, HVAC – works. Anyone have any idea why the wipers, even with the fuse removed, would come on like that? The windshield was leaking onto the dash for a couple of months, but I fixed that. Maybe some water damage to the electrical system?
Thanks!
