2000 vette wipers randomly turn on...any help

The 99 Vette that I'm buying in a week is (or was) doing the same thing. The current owner took it to the shop yesterday. The problem though is that the wipers are no longer doing it. He said the mechanic was still looking into it. It started doing it a few weeks back. I recall a few ago back having to take my 95 Blazer in for a recall to seal the wiper motor. I talked to the mechanic and he said that one some wiper motors moisture was getting in it and onto the circuit board causing the wipers to come on by themselves. If you experienced the problem they R2 the wiper motor. If you didn't they took some RTV and put a bead around the motor flange. The car is now in the panhandle of FLA and I'll be driving it back home to Las Vegas the week after next. I was hoping there would be a wiper fuse just in case it came on but I couldn't find one on my friends 04.

C-5's are known for the cowl drains to fill with debris and then the water from rain storms or washing that would normally drain from the cowl builds up and it will eventually flood the wiper motor assy and it usually ruins the entire assembly. So replaceing the wiper motor might fix your problem for the time being but next time your in the rain same problem again. So you have too keep the cowl drains cleared. the drivers side has two drains and they can be reached from the engine compartment if you just feel around with your hansd sort of under and to the rear of the hood latch. the passenger side I cant reach them so I have to remove the pass front wheel and then open the access panel in the lower rear section of the wheel well. Inside you will see the rubber tubes coming down from the cowl. the end of the tube has slots in it to allow them to drain. Clear the debris from them. If you have never done this then start with the pass side that way you can see what you will be feeling around for on the other side.

there is also a similar drain on the HVAC system that likes to plug up if it cant drain then you can flood the cars fuses and computer with water, because they are located right under where the a/c water drains to if the usual drain is blocked this drain is harder to get to because of some electrical wiring and the passenger side exhaust manifold limiting the space. the drain sticks through the fire wall on the passenger side by the exhaust manifold. I was able to get to mine from the botom of the car.I used a razor knife to slice the end off the drain valve so it would not plug up any more. the reason I did this was when I bought a 2004 spiral gray coupe for the wife, I saw that GM no longer used a closed off drain valve there it was just a rubber elbow to direct the water down. Mine is a Navy Blue Met. 2001 Convert. M-6 2 vettes for every garage.

And GM wonders why they can't sell cars.
