    Well my 93" Chevy truck wipers are acting up

    Here's whats going on, they will work for awhile then stop for awhile, however this is very intermittent. It's only done this twice this year with at least a dozen or more events this year, anyway any help with diagnoses.
    The truck does have intermittent wipers.

    this probably isn't going to be your problem but it wont hurt to check it anyway. the wipers on my 78 have been doing the same thing for a few years now. ended up being a partially broken wire going into the motor. like i said i doubt that's what is wrong with yours but check them anyway. good luck :)

    Well one of are trucks 97 chevy had a recall on the wiper motor. same problem stated above. circuit board in motor has a crack in it. so the motor wasn't getting grounded. We fix it by simply running a wiring from the metal case to ground, like the mounting bolts. I really hate taking our trucks to the dealer. Since the last visit back when we bought it. We had some problems. One week later I was over looking the trucks. And found that the boots on the lower control arm were neatly cut. Most if not all work is done in shop. Not by some flat rate mechanic. Sorry

    This is a common problem and is usually caused by a faulty circuit board in the wiper motor. It's very simple to change. I'm not sure if it is more cost effective or if the part can be purchased at parts stores other than dealer. The wiper motor is mounted to the "firewall". To replace the circuit board
    1. Remove the electrical connector
    2. Remove the torx screws holding on the cover (2 or 3 screw don't recall)
    3. Remove the torx screws holding the circuit board to motor housing
    4. Remove circuit board

    I had the same problem with my '94 and two '97's. The circuit board in the wiper motor went. There was a TSB or recall (can't remember which) on them. The soldering on them wasn't that great and after time they would just go.

    Try this if your wipers still aren't working........turn your wipers on, pop the hood and slap the wiper motor with you hand repeatedly. If they come on while your doing this then you know for sure the motor is bad. Worked for me every time.

    It's probably that problem with the circuit board not grounding correctly...just run a jumper wire from the motor housing to the body right next to it and you should be all set...such an easy fix it's certainly worth a try. I had this problem on my truck and it solved the problem...took all of 10 mins...btw, be sure to grind off the paint in the small section where you are going to attach the wire to the body or else you still may not get a good ground connection! =]
