[Blackhawkdc]

I did install the intermittent wiper switch in my 69 and got it working. I also checked the price on the switch at work it looks like $50 give or take some change. Heres some pics of how the install went.

I had the dash allready out so it was pretty easy to start.
the switch is pretty big as you can see.

I have an ancient aftermarket wiper delay in my '70 CST/10 that my Dad wired in eons ago. It finally quit working last year, and in the box of parts I got from my Dad with the truck, was a Ziploc bag with a new exact duplicate of one of these units. But Dad had it mounted below the steering column and it was always a pain to use. I'd like to try and make one of these cole hersee switches work. Too bad this thread died short of it's goal.

Absolutely 100%.

I find it odd there has been multiple companies that created 1pc window kits for these trucks yet don't see a market in updating items that can significantly impact the 'drive' in them. Sure, 2spd wipers get it done but those of us who have put miles on them regardless of the weather know the intermittent option would be gladly welcomed.

Exactly! There are lots and lots of intermittent switches out there to splice in and install, but you would think after all these years, ONE of the big aftermarket companies would have come up with kits that are dang near plug and play for under 100 bucks.

You could try contacting twouvakind, he built a lot of plug and play delay modules. I bought mine from him in 2016. I see his last activity on the board was back in January of this year. When I was looking to buy one it did take a little while to hear from him, but he got right on it and made another "batch". If he is no longer making them, you can buy all the parts and put one together yourself, but give him a try first, it will, save you the hassle of sourcing the delay board and potentiometer plus connectors.

@Orange Crate Appreciate it man!

I see LMC is now selling an Intermittent Wiper Module:
P/N: 36-0902......$72.95
I don't know if this is the original Cole-Hersee device, or more likely they got hold of an example and sent it overseas to pirate their own version.
I have no experience with this iteration, and wonder if anyone else has?

[Orange Crate]

I doubt the LMC unit has been hacked from the unit twouvakind was putting together. His had an infinite delay between 3 seconds to 30 seconds. See below for the LMC discription.

"This wiper module provides intermittent settings for 3, 5 and 8 second delay intervals"

I think I paid $60 plus shipping for mine in '16. Which is a great deal when you consider just the logistics of putting a number of these units together. The delay board is $12 and the extended shaft potentiometer is about $6 plus rolls of good wire, connectors and case. That's about $25 just in parts without the 2 hours to assemble. I would keep trying twouvakind just because he made all the other ones almost for no profit (maybe he has better things to do now...)

[SCOTI]

Seems a profit should be made. People should be paid appropriately for their time & efforts/knowledge invested. I certainly have no issue w/paying.

You Cannot substitute a Cole Hersee 75601-06 with any other variant of that switch, apparently.

My first update to this thread was Post #36 up top. I have had Leon edit that post because I was wrong: Cole Hersee made several SIMILAR but not identical switches, and they all have different wiring to some degree. This was more important than I originally thought.

Two nights ago I hooked up the whole shabang using a Cole Hersee 75600-04 on my test bench and FAILED. I couldn't figure it out. I did some digging tonight and found a few little nuggets of info.


Apparently there was an update to this thread from 2004, and look at the last post of that thread:
http://www.67-72chevytrucks.com/vboa...144#post737144
Boy I wish I had read that before buying the switch, but no matter, that's done.
Back to the drawing board.


Here's something cute and somewhat related to this thread: again, no part numbers or details(makes sense, he was trying to sell his product), and they're not around anymore...

I would like to quickly bump this thread.

I ordered and received a used Cole Hersee 75601 switch and tested it, wired it exaclty like blue_69 did in Post 4 http://67-72chevytrucks.com/vboard/s...963#post215963

It works perfect.
The specific switch part numbers have characters at the end such as 75601-08, or 75601-04, 75601-XX , it sounds like those last two digits don't necessarily change anything, it's the first five characters that need to match: 75601.

So the DIY intermittent delay wiper mod for 67-72 GM trucks only works if you can source a now-obsolete and not-for-sale-new 75601, try eBay, they're not unobtainium yet.

It sounds like they were already obsolete when this thread started, and thats why this thread and other "delay wiper kit" threads died.

I'm sure they'd sell if someone could find 10-20 of these switches and followed blue_69's wiring.

[Orange Crate]

Fixed it! Ok, NOW I see how you wired it..... Did anyone try twouvakind yet? I think that if someone was to make a delay kit it would be difficult to gauge the market. As I stated above, you would need to know how many delay boards, potentiometers, wiring, cases and connectors to order. Everybody knows that if you can buy in bulk normally the price would go down. Twouvakind was doing small batch runs and I dont know how he was making anything for his time.

[blue_69]

next i marked where the little square holes on the trim ring line up with the sheetmetal underneath and drilled them. Then I used taper head sheet metal screws and kinda countersunk the holes in the trim ring.

[blue_69]

then i mounted the trim ring and drilled the hole to 1/4 in the original knob and put it on the new switch.

[blue_69]

now for the wiring i drew up a schematic the wire colors match the wire colors on the new switch up to the relays. All in all i think it could be acomplished for around $60 - $75 maybe cheaper if you work at a place that sells the switches like i do.

[T-4301]

I am new to the forum but I have learned a great deal from you guys in rebuilding my 72 K20.
I followed your wiring diagram but what I get is fast wipers at key on with the switch off. I can rotate the switch to fast and the wipers go to slow speed.

What did I do wrong?

Thanks for the help.

[blue_69]

cole hersee makes the switch www.colehersee.com. The one i have is out of a blue bird school bus. The only place that i can find that carries cole hersee switches are heavy truck and bus places. If you get a switch for something other than a blue bird the wiring may be different cole hersee has a bunch of switches that look identical but they are different. And yes i was thinking of putting together a kit of sorts but i have to see if i can get a little bit of a break on the switch prices. I will post when i know more about that.

Man outstanding work!! That looks great, and fairly easy.
Are you going to sell the switches?
I cant wait to install ojne!!
