Year of car? In a 1992 Buick Park Avenue there is a circuit breaker for the wiper motor, if the wiper motor gets to hot the circuit breaker will protect the wiper motor from overloading. After the wiper motor cools, the breaker will reset. And a fuse also protects the system, which on mine it is fuse #5. You got me on the relay because I didn't think PA's had them.

When your wipers stop in the middle on inter. can you turn the wiper switch to hi, low, etc., and do they work then? If yes it sounds like your circuit breaker is fine. Two other things could cause this, the wiper motor, and the wiper switch. What you explained really sounds like the wiper motor is bad, the electrical deal inside the wiper motor assb. etc. Some great advice, don't buy cheap parts for these cars, you should really buy OEM parts, (exam - ac delco), they cost more but the quality is unbeaten.

If you can try to have this happen with the car in park, then if it does stop, wiggle the electrical connector at the wiper motor, and knock on the black plastic housing. If no results, don't rule out the motor yet, just wait for some more replys here.
