I have a 2001 Corvette C5 48,000 miles, all of a sudden today the wiper blades comes on by themselves jump up in the air and fall back down on the windshield while driving, anyone else had the same issue?

 

has the car been in the rain or washed not toolong ago

 

Yes it was washed yesterday and for two days before that we had rain

 

make sure your utters are clear,i think there are 3 ,all under wipermotor.snake your hand around the brake booster .ya have water in the wiper module ,its bolted to wiper motor underneath. you can hope that it will dry out or you can pull the whole thing out and dry it out.to test it the right way you should undo elect. jack under steering col. and see if it happens again.if it does the switch is okay.if you pull the wipermotor DONOT remove the center torx bolt on wiper arm

 

Ok, I will try that over the weekend, thanks, I will be sure to post the results.

 

I could not locate the term "utters" in my book, would they just beneath the cowling under the windshield wipers?

 

yes. ya gadda snake yer arm around booster but basicly they are under wiper motor.look for wiperwasher tanks elect. connector ,one utter is 6 inchs to the rear

 

Ok I found them and they were filled with junk, that I hope will be the problem, thanks.

 

well it aint gonna fix the problem just stop it from occuring again,you may still have to pull motor assembly and remove module to dry out

 

Well I found two cleaned them out replaced them now the wipers don't work at all, but maybe that's a good sign, maybe it is the switch.
