Would like intermittent wipers in my 78 GMC
I've read a number of threads about this, but it seems to come down to finding an intermittent wiper control module. Seems that the control modules are hard to come by. Does anyone know of a source for these, or an aftermarket solution?
Thanks!

Re: Would like intermittent wipers in my 78 GMC
Were intermittent wipers even an option with the dash-mounted switch?

Re: Would like intermittent wipers in my 78 GMC
I believe they had an option for intermittent wipers these years. Instead of the metal square knob for the wipers, there would be a little round black knob with an arrow on it. You turned it to adjust the intermittent. I don't think they worked very well....

Re: Would like intermittent wipers in my 78 GMC
Yes, they would look like the picture posted above.
Adding the intermittent portion is pretty easy, as you’ve read. It’s been added to my ‘78 Chevy, and is as simple as finding the module on a parts truck, and the module is plug and play. As far as I know, the module is not currently being reproduced by anybody, and supposedly they have internal component failures, but I’ve seen them be repaired before. Your best bet would be to find one at a wrecking yard or someone locally parting out one of these trucks, and bring your truck so you can test it easily. |

Re: Would like intermittent wipers in my 78 GMC
I had a 79 Camaro with a switch similar to what Corts60 posted. The intermittent function worked fine until something went wrong and the wipers wouldn't turn off reliably.
Guessing you could expand your parts search to all mid to late 70's GM vehicles and not just trucks. A lot of parts from that era were common across the various GM lines. |
