My wife has an S-10 with 4.3 in it and the wipers and washer work when they want to. Sometimes they go for months and both work fine and then other times, they will stop (usually in the middle of a downpour while cruising down the freeway at 70 mph) for no apparent reason.
Has anyone else had this issue, and if so, how did you fix it?? It doesn't appear to be related to the switch on the steering column, so I am assuming it is in the circuit somewhere.
Thanks...
