2006 Pontiac Solstice - Wipers turn on by themselves

Here’s a new one:

Three times in the past week, the wipers have randomly turned themselves on. Each time turning the switch on and back off has fixed the issue.

I haven’t seen anything else indicative of an electrical problem.

Suggestions? It’s a 10 year-old car, but it seems odd that the switch would just give up the ghost when it hasn’t been used in a month. (Dallas – rain is only a fond, distant memory.)

Update

Yesterday, I got stuck in Dallas traffic and the car started to overheat (around 220F). The car died – I’m guessing the computer shut it off to prevent damage, but that’s just a guess. I let it cool off for awhile, ran the heater full blast, and got it back down to about 180. I then drove it to the closest gas station.

Checked the oil, nothing on the stick. I had to add 3.5 quarts to get it back to a normal level. (Added a quart, let it run for a minute, checked. Repeated until it got back to normal.) Capacity for this engine is about 5 quarts (ECOTEC 2.4L, LE5).

Coolant level was normal, but I don’t think the radiator fan is turning on. Driving back home, the car died on the side of the road again. That time, it wasn’t that hot – about 200F. It would start and run for about 30 seconds, then shut itself off.

I had the car towed home. This morning, I checked all the fluids again and everything seems normal. Now, it starts fine and continues to run as normal.

Sounds like an electrical problem. I’m wondering if oil getting thrown around the engine bay has caused a short. :/

Now looking for a mechanic in the north DFW area that will work on modified cars.
