Occasionally I see an intermittent wiper dash module for sale on eBay. This is a nice-to-have feature I wouldn't mind having in my truck. To replace the standard 2-speed wipers my truck currently has, is swapping the dash module enough, or does this feature also require a special wiper motor and/or wiring?
-
IIRC, on trucks with the wiper switch on the dash, it is pretty much plug & play. The harness unplugs and the delay module plugs in between.
On my 79 I swapped to a later column with the wiper switch on the column and it was a little more complicated.
-
An aftermarket system comes with everything you need.

all you need is the switch and delay module out of a truck that had a delay wiper switch in the dash..plug and play

Yep, here's anew one I bought, but this is all you need. It's two pieces; switch and module.

78 Chevyrado,
Where'd you get a new switch and module? Are both units combined into a single part number? Is it a genuine GM part?
-
I bought mine new from classic parts of america. The switch and module are sold seperately. They are Genuine GM Parts (both of them) in ACDelco boxes. Classic parts doesn't say that it's GM but it is. The module is kind of expensive, if you're on a budget find that part on ebay. This setup fits 78-83 models.
Here's the switch: GM PN# 14028808

Here's the module: GM PN# 88960364

I have since found them on gmpartsdirect.com for $5-$10 or so cheaper, each. You might do a part number search to find a better deal, I just didn't have the part numbers until I bought them.
-
They are still availible from GM also (which is what gmpartsdirect is)
-
I just have to say it again...
This forum rocks!
(thank you!)
-
I have that same switch from a monte I think, but it don't have the module. I understand that just the switch and a delay wiper motor should work. and the switch/module and a regular wiper motor should work together.
Right??
-
I've got the same switch & module that 78 Chevyrado showed in his photo (http://tinyurl.com/kwacr4). If it's important, the switch is part #14028808 and the module is part #14056657.
The switch & module were removed from an '85 by someone else by cutting the wires, so my question relates to wiring.
The pigtail that plugs into the module has 6 wires, labeled A through F, as follows:
A = GRA
B = BLK/LT BLU
C = GRA
D = PL
E = BLK
F = PNK
If it matters, "A" looks slightly darker than "C" (not the exact same color gray).
All I have found is a detail of the "pulse wiper system:"
(http://gregburrus.com/wiper.bmp)
However, it doesn't tell me where the wires go, AND it only shows B through F (no second gray in the A spot).
Can anyone help as to where connect my 6 wires (A through F)? Many thanks.

This forum truly is excellent.
Question about the module though.
The link above is no longer good, can anyone recommend a good module?
I see a few online for $80, but it seems a bit steep, no?
-
The delay modules, switches and wiper motors have several different variations. Need more info on what setup you have.
-
Thanks Vile. Sorry I missed your response until just now. (I had forgotten to turn on the notify button.)
I'm replacing my whole wiper system right now, so the setup is interchangeable.
1. I'm looking for a new wiper motor and am having difficultly finding one in general. Any ideas?
2. Once I get the wiper motor operable, I'd like to patch in a delay to a new aftermarket switch and have intermittent wipers.
At this moment, I've stripped everything from the truck- Wiper motor, washer pump, wipers and linkage. After 48 years, you can imagine it's beat up.
I've opened the wipermotor- the gear seems fine, the rotor rotates and such. But again, it's just beyond it's shelf life at this point.
-
Thanks Vile. Sorry I missed your response until just now. (I had forgotten to turn on the notify button.)...
My guess is that what VileZombie was requesting was details about your specific vehicle. Year, model, customizations, etc. Every little bit helps.
-
You're right. Thanks, SilverMiner.
It's a 73 C20. Everything is stock and needing to be replaced slowly but surely- specifically much of everything that is electric.
No modifications on the truck.
I'll attach some pictures as well.
(I've actually used this as an opportunity to test cleaning up the engine bay. Also shown in the photos.)
-
After further digging, this seems to be the best I can find at the moment. eBay and Amazon of all places.
Nothing on Classic, Summit, PartsGeek, etc...
This one from Premiere states it's built brand new:
https://www.amazon.com/dp/B01C5ORK0G/ref=nav_timeline_asin?_encoding=UTF8&psc=1
Anyone ever hear of Premiere before?
This one is Cardone, but upon observation, it seems it doesn't come with grommets?
https://www.amazon.com/dp/B000C455J0/ref=nav_timeline_asin?_encoding=UTF8&psc=1
Does anyone have any experience with this?
-
40-160 is the A1 part number but they're getting harder to find. I'm glad I have several in stock for my stash. You switch over your grommets or you can buy them on eBay. Other options is used, rebuild or retrofit to a different motor and system.
-
Thanks Vile. The part number is super helpful.
I e-mailed Premiere to see if it would actually match as it looks identical, but Amazon clearly states it wouldn't fit my truck.
Earlier in this thread, CaptKaos mentioned GMpartsdirect, but they don't seem to service anything beyond 84.
I did see grommets available on Ebay for about $15- I bookmarked that for now.
Again, if anyone has any recommendations, I'd be very grateful. I tried , but they don't stock either.
Also, I'm learning that the washer pump is actually the cover for the wiper motor... Kind of a poor design, no?
-
It was a bit wonky and noisy but it's up to you. Some people are purists and want to keep it all factory. You can adapt and make whatever you want work in its place. For my 74, I completely hid the wiper motor inside the cowl for example.
-
Thanks again, Vile. I'll just proceed forward with good judgment and make a solution.
May I ask/confirm three questions though?
1. My wiper linkage is ugly and a little noisy, but operable and out of sight.
How may I quiet this? Will a bit of WD40 and some grease at the ball joints do the trick?
2. I'm still trying to confirm the power supply of the wiper motor. Is it receiving its power from the fuse panel?
3. Confirming that whichever motor I use, making them intermittent is nothing more than correctly patching in a delay and using a proper switch, correct?
-
clean everything up with scotchbrite and then use brake grease or white grease. Yes and the switch grounds low and high speed. Match the delay setup and switch for whichever application you decide to use.
-
You're the best. Thanks for the help on this one, Vile.
I'll proceed with confidence and post pictures when completed.
-
Hey Guys.
I'm attaching a photo of the wiper motor I purchased.
What is this copper-colored metal flap coming off the grommet? Is it a ground that I am supposed to bend and fasten to the washer pump?
The wiper motor is a Cardone 40-160 that I found at PepBoys for $40.
Great price and seems alright, but this paint job is junk.
I removed the stickers very slowly, but the paint came right off- so, I'll be painting that tomorrow...
-
Found it online. What I was questioning is called a grounding strap.
So, I'll just gently roll that over and bolt it to the motor itself using the washer pump bolt.
-
Yes, ground strap and known to break. Glad you found one so cheap!
-
Vile, thank you for your help. It's greatly appreciated.
I've replaced the new wiper motor. For anyone reading this in the future, I'll add a small tip that I learned while doing this.
-Mount the wiper motor to the firewall first, and then the washer pump to the wiper motor.
If you mount the washer pump to the wiper motor first, your grounding strap will be blocking one of your mounting holes.
I will say, I'm fairly certain I've mounted the wiper motor correctly, but the wiper motor isn't flush to the firewall- there's about a 1/4'' gap.
I feel like there should be a weather strip for this, no?
Did I install incorrectly?
I'll share pictures below of the job. (As mentioned, I took this as an opportunity to clean up the engine bay as well.)
Now, on to research which wiper switch and delay will be best for the truck.
Given that the original links to such products in this thread are kaputt, I would appreciate any leads anyone may have!
Thanks again, Vile!
-
Butyl tape (dumdum) is what you will generally find where the motor meets the firewall.
-
Ha... at first I was like, who you calling a dum dum?
Thanks Vile.
-
lol, I'm not entirely sure but I think dum-dum was a brand of butyl tape. I really don't know why it's called dum-dum
-
From my recollection of historical trivia, the term "dum-dum" originated near the close of the nineteenth century, coined after the British Dum-Dum arsenal in India where the first expanding riffle round was developed for militia applications (precursor to a modern hollow-point). The pliable 'dum-dum' round expanded and mushroomed on impact causing a debilitating injury while imparting full impact energy to its target similar to being clubbed. Similarity between the appearances of an expended dum-dum bullet and easily deformable plastic sealants/fillers invited adoption of the term.
The worthless trivia you pick up as a kid... ::)
-
Super interesting, BD.
So, is this to assume the Dumdum tape expands after applying?
-
lol No. It just exhibits high pliability and conforms to odd-shaped spaces easily.
