Wipers dead

[shiftpro]

Seems like I may have a toasted wiper motor. Driving home last night in a terrible thunderstorm and raining hard, first my pisser wouldn't quit then everything stopped. Oh that was fun driving at night with no wipers. So my wiper motor is warm as well as the switch inside the cab.
Should I expect it's fried? Weird how the washer fluid pump wouldn't stop before everything finally did quit.
Oh I hit the washer fluid because there was some smears on the windshield the rain wasn't cleaning off.
Any ideas I'm missing?
Thanks

Hot wire the motor. Then you will know it's just the switch.

Thanks Brent, there is power going to the motor.
I'm wondering if the motor frying has something to do with the pisser pump not shutting off.
Waiting for the RAIN TO STOP so I can check my other cabs which still have wiper motors on them. This truck is an '81 and my '86 has a different motor,
not that I can take that off I still use that truck.

Funny how they have all these inline fuses, and a fuse box, yet all the **** seems to bypass all those.

Your wiper motor, and tank. My whole ignition.

God the good old days.

What year is the truck? I have 2 extra wiper motors...

It's an 81 Ted.. Thanks for the offer. Are your motors new remans or used? If you have a reman motor that is new and you don't need I would be happy to buy it from you anyway. At this point though, I need it now and see where I live...? It looks like we're getting rain for a week at least, which is good because we really need it.

Im not sure for certain. I bought them used from a squarebody parts clean out but i think mine are older. Does yours have the squirter on the motor?

Just do your checks to verify your changing the right part when it comes to electrical it could be anything you know does sound like a motor BUT definitely could be the switch or other parts of the circuit you know!

Yes the 81 has the pump on the motor.
My (I think) 83 has the pump in the tank. My 86 has pump in tank.

So, I don't know what the hell I did but now they are working.
Strange how the power goes to the motor then to the switch and back, or something like that wtf.
Pulling the plugs (3), some wires have power even with the wiper switch off. Hit the switch and nothing changes. Hmm, magic.

What I did was I yanked on the driver's wiper arm and bingo they were working. The pump even though it wasn't priming itself was on all the time so I unplugged the dude. Now I have to turn the wipers off at the right time or they just stop where ever.

I do think it's high time I buy a complete new unit and save the existing one for parts (btw, it says reman on it).

I don't know if you have intermittent wipers, but I had to replace the pulse control module on my '85 recently. The washer would not work, although I had a new pump and every time I started the truck the wipers would cycle 4 times. It would then randomly cycle as I drove it. Once I replaced it everything works correctly.

Not the intermittens thanks Craig for bringing it up, but the two speed switch on the lower dash. 1981. << that one.
One of the perks I guess of pre signal lever/wiper/cruise is you don't have to eventually face a steering column proctologist gig.

So was the subsequent pump-in-tank a better design...?

Rock Auto says '85 the motor lost the pump. I guess my 83 is an 85... wahoo I gained 2 yrs!

Imagine that... only lasted 39 yrs what a piece of junk.

Just thinking... I bet a any new truck's wiper motor would cost more than a square body parts truck... and would take as long to replace as restoring a square ground up.

And then it wouldn't fricken work and warranty only pays once...
