Delay wipers in a 78?

[bigcountry78]

First year for delay was 1977. Unreliable but a pretty rare option for that year. Re-designed in 1978 and carried thru until 1983. Then became a common feature beginning in 1984 when GM moved the wiper switch to the turn signal stalk.

So would I need the parts from a 78-80 truck to work, or would up to 83 work? Is it pretty much plug and play?

From 1978-83 it is all plug n play with what you currently have. However whether the module internally is good is another matter. I overhaul certain aspects of the circuit board and bench test them with a new switch to verify their operations.

Oh ok. Do you have any available right now?

I’m out at the moment but I have 3 that I need to re-furbish with new internals...if you can give me a few days I’ll have a couple more ready to go!

 

[bigcountry78]

Sweet! What is your going rate?

A refurbished module is $75 shipped.

Just keep in touch with me on them-they go quick once I have a few for sale.

Will do, thank you sir.

My switch was bad on mine so I bought a new one, when I when to use the washer the switch came apart. Why is it so hard for a company to make quality products these days.

China doesn’t seem to be big on quality.

Would that be the same if i shipped you my old one to refurb and send back?

 

[harcorshe]

Ditto for me. I have the old one and could send as a core or have you fix it. Thanks!!

 

[gmachinz]

I will do a module re-furbish for $45. I’ll cover shipping back to you-just send it to me. I’ll bench test the module and send a little video demo once its finished prior to shipping back to you.

I'm thinking this one would be pretty much free. Put in another switch next to your high/low (floor dimmer) switch. I thought it was a joke at first, but really, it's pretty clever....

I heard of someone putting a floor mount head lamp bright switch in but modified it so that it didn't lock into position. It would make contact when pressed and break contact when released. Anyways...fella hooked it to his wiper motor so that he could just step on the button to bump the wipers. Guess it makes it easier to drive while holding a beer and smoking a camel. IDK. Just thought it was ingenuity at its greatest.

Classic seems to have the delay modules for the 78-83 trucks. Around $100 so it's not cheap. https://www.classicindustries.com/product/g10140.html
They have the switch as well for around $50. Not sure what the quality level is tho.

Both the 78-83 and 84-91 modules are not Potted and the through hole components are available. Sooo... If you have a dead one it can usually be repaired by a competent electronics repairman. Probably for less than the cheaply made Chinese replacements.
