wipers are slow

[fallen]

Just got my second blazer this week. The wipers run very slow. If you pull them off of the windshield they seem to run at the normal speed. The system voltage is good. Has anyone had this problem before. Thanks in advance.

My M1008 start out super slow and gain speed after a bit. I'm not sure what that means either.

My M1008 did the same and I replace the wiper motor. It runs great now.

Wiring

Mine was slow, so I did a search for "CUCV wipers" in the forum search. I found several different threads listed. Most pointed to wiring. I found a bad ground on mine and they work great now. It would be to your advantage to check/clean every electrical connection on the CUCV since it is that old. A bad wire may not be your problem, but it's the easiest and cheapest repair if it does work! Hope this helps.

Also remove the cowl trim and lubricate the linkage. After 25 years they get dry and stiff. The extra friction really slows down the motor.

Mine were slow too...did a capacitor (i think that's what they are) bypass and screwed in a new ground and they are much better.

how much do u have to take apart...?

 

[pgwaldner]

Just 4 screws at the edge covered by the hood, remove the wipers and wiggle it out. Spray all the joints with WD40 or Blaster and reassemble. Not too bad.

 

[lindyp38]

im gonna try to do that.........thanks

WD-40 and PB are good lubes, but it you want it to last, clean all the dirt and gunk off and rub some lithium grease (out of the tube) on each linkage. The stuff lasts much longer (IMHO) and is what they used coming off the line. The same thing is great for all the window mechs. Just make sure you strip off all the gunk first. It doesn't work as well on top of gunk.

Just my 2 cents.

 

[pgwaldner]

mr.travo is right about the lithium lasting much longer. The WD40 is good for washing the gunk out as it thins the years of dried grease.

 

[mr.travo]

Ya, I just into doing things only once (nothing lasts forever but you can sure try and make it). If you're going to go through the hassle of pulling parts and doing something, might as well take a little bit of extra time and do it right.

I agree with you about the grease lasting much longer then the WD-40, etc. You mentioned using lithium grease out of a tube. Is that substantially better then using the spray form of lithium grease? Sometimes it is easier to get the spray nozzle into tight places!

 

[acesneights1]

Mine do the same thing. I changed mine over to delay wipers but same thing.

 

[mr.travo]

I think it's better than the can. It's probably 6 of one and half-a-dozen of the other though. I agree with you about the can being able to reach tighter places. I personally just don't care for the over spray that I usually cause

I did an upgrade to get intermittent wipers and better washer system from a 87 Civy Crew Cab my documentation shows how to disassemble to access the linkage:

[fallen]

What items did you have to swap out. I'm guessing the motor and switch at least. Was all of the wiring correct? I am trying to locate the hub caps for the front any ideas where i could find some.

 

[48cj2a]

I had already installed a tilt wheel out of a junk yard that had the intermittent switch already in the column and obtained the intermittent module at the same time. I swapped wiper motors with the crew cab donor to eliminate the washer pump intregal to the motor as well.

Column Switch
Intermittent module
Motor
Washer bottle w/ intragal pump and harness
Wiper arms with washer hoses and "T" or "Y" adapter

I removed the resistor wire from the harness that plugs into the wiper motor on my M1009 about a year ago and the wipers work great now. The connector plugs are duplicates and it will still plug right back into the wiper motor. I understand that the resistor was mainly for suppressing radio interference, and not to cut 24 volts into 12 volts.

 

[HeadWizard]

Taking the resistor out should raise the voltage some allowing the motor to run at a higher speed. That would mean that the voltage is low to begin with. Bad ground or connection is the most likely cause. High friction in the linkage the other culprit. Clean all grounds and connectors. Clean and lube, clean and lube!
