    I have a 92 chevy truck and my wiper motor is quiting. What will happen is it works fine, no problems until I use it for a while. Like today I ran them for about 15 minutes and then they just stopped. I kept moving the switch from delay to high and nothing. Then about a minute later even though it was on high it started to act like it was on delay. It would wipe every 5 to 10 seconds or so. Then it slowly sped back up to the high speed. Then worked fine for about another five minutes and started all over again.

    I'm thinking it's the wiper pulse board. Am I correct on this? I have heard they go bad. Otherwise what do you think it is?

    Sounds like a bad switch to me. Mine quit working altogether a while ago and it was just a bad ground to the wiper motor which is just bolted to the firewall for the ground. scraped away some paint where it bolted to and worked fine ever since

    wiper motor here <--- Just changed mine on my plow jeep with the same symptoms.
    When you think about it the switch turns it on and off.Switches rarely work for 5 min then stop then work again it is electric. i used a full an of crc contact cleaner on the switch and no change. Then ran a test light for about a half hour and it did not go off once but the wipers stopped several times. After the motor change no problems

    the wiper switch is a basic rheostat. it is designed to send a pulsed signal. it could have a bad connection, causing it to stay open.
    just wanted to clarify that, not saying it couldn't be the motor

    edit: rheostat may be the wrong word, but this is the basic idea.
    crab or 75 can clarify if i'm wrong

    Common problem for those years in easiest order (mostly)
    Try taking the cover off the motor and looking for evidence of water getting in from top.
    Also look for solder joints that may be bad (cold or cracked) and fixed quickly with an iron.
    Joints are on "back" of card so go in with your #20 torx and pull connector and ease card out.
    Recall for 95 and up trucks but prior years having similiar problems.
    Could be a dab of sealer or 30 seconds with an iron will fix you up.
    Dealers that had them were selling cards for $45 but you could get them elsewhere for $28.
    Dealers that didn't would have you substitute 95 pump with card since it works with some of the older trucks.
    Sometimes folks run into too much grease built up near gear clogging contact.
    Also check grounding screws for rusting / bad contact

    Mud: trying not to correct anyone lest I start a trend that will bite me...

    Yup, you should just check on where the wirings lay and maybe it's somewhat stuck only. And find a place where it would function properly. But if not, maybe a new wiper motor will do.
