    hello, i have a 04 gmc full size 4.8 l pick up, every time i use the wipers i have to pull the fuse or wait overnite to be able to shut them off, the only function that works is high or low.......i start off in delay mode and they go into one of those two by themselves and wont shut off ?? thanks Joe

    Actually it's due to a failed PC board on the wiper motor. Happens from time to time but it's a 10 minute fix with a $50 replacement PC board .
