update on intermittent wipers
 

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.

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.

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

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.:)

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

what is the switch originally for?

that is very sweet... i folled your other post but just as a refresher what kinda switch is it again????

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.

Excellent info, I moved a copy of this to the FAQ board.

is there suppose to be pics??? on the main page it shows the little paper clip like icon to denote pics ... but when I open it, there arent any?

Uuuuummmmm, there was pics. . . . :confused:

Do you have the Cole-Hersee part # ?
Looks like I better buy some C-H stock tomorrow!

umm oops....... I guess when I copied the thread it kinda screwed up the pics.... Email the pics to me chevy69@grandecom.net and I'll edit the posts and re add them.

Greatttt. I'm going to check back tomorrow for the pics. Big thanks to blue_69.

We Want Pics! We Want Pics!

Seriously though, I'll just check the FAQ board later. I was thinking about this awhile back when we had light rain, kept turning the wipers on and off. Thanks for the info.

What is the part # for the switch?

I don't need intermittent, I just need REASONABLE!. Mine are so sloooooowww.

I updated this thread with the pics and also the thread in the FAQ's section. I planned to get more info on availability today but my friend in the parts dept. left early. If i can get some switches and relays for a reasonable price i will post them on the parts board. How much would you guys think is a fair price for this deal it looks like it will be somwhere between $50 - $75 for the whole deal relays all wired up and ready to plug in to you existing plug.

blue_69, wired & ready to install @ up to 75$ sounds fair.

ill take one

I would pay that for it.

Sign me up~!

I would take one at that price!!:D

Are the relays internal to the switch? Or, are they additional items to be added and mounted? I am guessing that the "30" that you show for each relay is an amperage rating...is that correct? The numbers "85, 86 and 87" are all connections on the relays, right? So, all three are identical.

Boy, I sure do ask a lot of questions.

Nice job on the schematic. It is plain enough for me, so everyone else should be able to understand it, too.

I got a price on a switch today, of $60, from our bus parts supplier. I am guessing this is comparable to yours. I sure need to see the switch to compare the wiring coloration.

You've been a help to lots of folks with this info!

Great work Blue! Thanks for you time and effort. This will aid all of us in getting the upgrades we desire. Jeff.

Blue 69,
Thanks for taking the time to share this info with everybody!. Will this switch make my wipers FASTER or just intermittant?. As I said mine are super slow........Jim

Here is a helpful diagram of standard auto relays. A coil is used to 'pull' a switch. The switch can switch on power, or complete a ground, as it is doing in the wiper circuit. Wiper motor gets power at all times. On our series motors, there are 3 possible combinations, plus washer operation. For you techies, here are the combinations:
Park and off = lt blue and black connedted, (not grounded0
low speed = lt blue and black grounded
high speed = lt blue grounded
washer = dark blue grounded

blue_69, what was that part #?

If you build it, they will come!
 

I would sure like to see you put the complete package together and make a few bucks for your time & knowledge. I sure don't want to run around trying to find this stuff.
OK, I get to ask one dumb question: Does it park in the Off/down position? I had an after market kit that was just timed & stopped where ever it was when the time ran out. If it was in front of your face, you had to tap the horn to get it to move a little farther out of the way. LOL. J.C.W. special.

The Cole-Hersee part # is 75600-04. I checked with a couple of parts dealers and they go from the low of $44.00 to the high of $60.00.

IS anyone going to package a intermitent switch setup? I'm not a relay expert, are the 3 relays shown in addition to Bus intermitent switch? Where should they be mounted? Maybe I'm missing the update somewhere else. The rain is really starting to fall on West coast now!!

I WOULD SURE LIKE TO BUY ONE OF THESE KITS, WHEN THEY ARE PUT TOGETHER. PUT ME DOWN FOR ONE.

good job and much needed info

I would love one too....I'm not an engineer, so as long as it's pretty simple to install!!!lol.

Re: update on intermittent wipers
 

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.

Re: update on intermittent wipers
 

Raising this thread from the dead to update, I believe the part number he used is Cole Hersee 75601-06

Just FYI, they made several versions of essentially the same exact intermittent-hi-low wiper switch with several different but similar part numbers, some of them had different color wires, some had more wires than others, and they all had different plugs, and some had no wire plug at all--just loose wires.

This handy PDF gives you build specs of all of the different variants of this switch, and if you look back to blue_69 original wiring image, you'll see he was most likely using a 75601-06.
https://peerlesselectronics.com/medi...s/75600-02.pdf

Due to further research, and after buying a Cole Hersee 75600-04 and trying it myself, I have found that you CANNOT substitute the original Cole Hersee 75601-06 used by blue_69 with any other version or part number.

It's a shame this didn't go any farther.

He hasn't posted since 2016, and hasn't been on the board since 2018.

:(

Re: update on intermittent wipers
 

I thought the same thing & even checked to see when the last time blue_69 posted as well.

Heck, I sent the intermittent wiper set-up I purchased from another thread to board member 68bowtie4x4 in hopes he would be able to build these for others & that stalled out.
Sure seems like a good idea.

Re: update on intermittent wipers
 

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.

Re: update on intermittent wipers
 

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.
