1993 D250. Wiper motor runs but wipers don't go back and forth. How to remove cowl?

[Motorhead]

An elder friend of mine just brought his 1993 first gen 2wd by saying that the wipers don't work. I had him turn on the ignition and turn the wipers on. The motor works but the wipers don't reciprocate. I grabbed the left wiper arm and moved it across the windshield with the wiper motor turned off. It seems to me that the wiper linkage came unhooked from the wiper motor arm.
It looks like I have to remove the cowl where the wiper shafts come through to access the wiper linkages.
I see the screws that hold the one end down. Are there screws under the windshield rubber to remove or does the cowl just hook under the rubber seal?
Is there any source for the plastic cups or bushings on the wiper motor crank that connects the motor to the linkages? Any tricks to safely remove the cowl? Thanks for any info. Chris

This happened on my '92. The plastic bushings fall apart. I got an assortment in the help section at O'Reilly's. They're cheap and there's three or four different pairs of them in the package. You will need to remove the cowl. I can't remember exactly how it comes off, but it wasn't hard if I did it.

Thanks Scott! Was it the bushing that hooks the wiper motor bell crank to the wiper linkage?

 

[BigPapa]

Yes, sir. I’d replace all I could. I don’t remember the exact layout.

Thanks again. I wish I had a first gen factory shop manual or parts manual for pictures of the assembly. I still have my second gen shop manuals. I don't think they will be of any help. Thanks BigPapa!

If you haven't done it yet, don't get the parts store bushings. This guy 3D prints a vastly superior linkage coupling system. https://jdg3d.com/products/wiper-arm-bushings The cowl may be a bit stubborn, if your windshield gasket is really stiff. But once you remove the screws/bolts that hold it on, it will come off. you may just have to wiggle it a bit. A putty knife or something similar will help get it back in under the gasket. It's an easy, if not infuriatingly fiddly job. So do yourself a favor and get the JDG Designs kit so it won't break again lol. Much easier to install than the old style bushings, no cussing while you try to force bushings into too small openings while working at a poor angle. Just need some snap ring pliers.

The guy who makes them is a member of this group on facebook, if you have any questions with the install. But it's pretty straightforward. https://www.facebook.com/groups/firstgendodgerams Dave Downing is his name.

Thanks! The assembly looks pretty straight forward. It's just getting my worn out old body up in there to do it. I'm 72 and ran packages for UPS for 30 years. My back is fused from L-1 down to L-5. I don't see any issues other than it will take me a little longer than it used to. Thanks Again!

A topside creeper makes things much, much easier. If you are still able to climb up onto it. I absolutely LOVE mine. I have this one https://www.summitracing.com/parts/...HahJoRIwVAB4ahro8UzYg6b2AUiZTCGNc44SO49Lte044

I have seen those overhead "creepers". Fortunately, the truck is a stock height D250. I have pretty much retired from most of my car work otherwise I would probably buy one of those. This guy that owns the truck, I have been working on his stuff for a lot of years. The truck is a real clean, low mile D250. He's 83 and doesn't drive much. It's a deluxe single cab with factory cruise control and power windows.
