Wiper motor R&R is it as big a pain as I'm fearing it is ?

[RainFade]

My wipers have one speed no matter where I turn the knob... GLACIAL , I mean slow would be a compliment to these things. With winter coming I want to fix this ASAP.

I haven't snagged a shop manual yet and was wondering if some kind soul could give me the broad strokes of removing this thing ?

Thanks,

Brian

What year truck?

From my 71 Chassis Service Manual:

1) Disconnect battery ground cable.

2) Remove wiper arms and blades from wiper transmission shaft.

3) Remove plenum chamber grille.

4) Disconnect wiper drive rods from crank arm; remove crank arm nut and arm from motor shaft.

5) Working under instrument console, disconnect wiper motor and washer wiring connectors.

NOTE: If vehicle is equipped with a parking brake assembly located on the vertical surface of the cowl front panel (directly below the wiper motor) remove the parking brake assembly attaching bolts (4) to allow shifting of the assembly rearwards in order to provide access for removal and installation of the wiper motor assembly.

Disconnect and remove left-hand defrost hose.

6) Disconnect washer hoses from washer pump.

7) Remove motor attaching screws and motor from cowl mounting position.

9) To install, reverse removal procedures.

NOTE: Make certain the wiper motor and blades are in the 'Park' position.




10) Wipe bloody knuckles on pants leg, pop top on favorite beer, and be glad you got it done without knocking a knot on your head while scrunched up under metal dash assembly.

Wow...there you go the Board comes through again!!! Great job SLS!!!

Also check your wiper arm transmissions while you have them loose. They could be about froze up causing wiper to move slow. (Hope you don't have AC-if so GOOD LUCK and have plenty of "suds" on hand.)

SLS you are the man thank you !!!! I LOVE this board
About A/C... I have dealer installed air is that bad, I'm hoping as it hangs under the dash mostly on the passenger side that it isn't bad, hate to unhook it as it actually works !

Thank you all so very much,

Brian

Lucky you!! (should be ok)

A/c just means you have to unhook some more ducts. It's not that bad of a job. It's a lot easier if you remove the heater controls, and even better if you have the instrument cluster out. Crawl behind the dash and assess the situation. There are 3 hex head screws that hold the drive assembly to the mouning plate. Just be careful with them, they break easily! I replace mine with flat socket head cap screws after I broke one.

Glad to be of service.


I needed to look at how it's done as I need to pull mine too. The wipers work great....but the washer don't put out any juice.

When I got the bucket o' bolts the tubing ran to nowhere so I got a tank and bracket, hooked up the tube, filled it up with fluid...and when you push the button a few times nothing happens....EXCEPT the washer pump gets hotter than 3 HELLS!

It has AC (or whats left of it) too, but at least the AC ducts shouldn't be too much of a problem...as they are dry-rotted to nothing but the slinkys.............dangling down to the floor pans (or what's left of them)...LOL.

Oh well, it's just one of 1,678 other things I have to fix.....

I must say it is a pain in the neck literally(mine is still hurting). Just replaced my wiper motor and i am guessing there must be an easier way than i [ upsidedown from under the dash] the whole time i was thinking about going through the cluster but didnt the job is done and working fine. Got a life time warranty with my motor but if they last as long as i assume was the original the it will outlast the part store i got it from.

[Fred T]

With the cluster and heater control out I didn't even have to lay down on the floor. Forgot to mention my column is out, too. Was able to do it either sitting on the seat or standing on the garage floor.

SLS - You don't have to pull the motor to replace the washer pump. There are two screws that hold it in place, use a 1/4" socket. The pump will fall off in your hands. I bought a rebuild kit for mine, found out it didn't have a diaphragm in the kit. Bought a new pump instead.

Mine is slow as well..........what am I looking at for a new motor ?

definately lower the column and remove the dash cluster...then you can see and reach everything much easier.
Consider a small electric WS wiper squirter mounted out by your bottle...auto parts item. Easy to get at if you have to change it in the future and it only squirts as much as you want, not 12 full pumps like the original.

That' a good point,squirt everything down with WD-40 before you pull it apart,might just save you a lot of work.

Take pictures and put a thread in FAQ while you're at it!
Have fun.
