My 79's Wiper switch works, high and low, but no intermittent? Any thoughts on why that might be, or how to fix?

I suppose it is possible that the PO installed a bypass on it. I see that you can no longer buy the switch, hence the need for the bypass.

I'd like to get it working again. Thoughts, suggestions?

Thanks!

Same on my 1981, My High and low works, but no intermittent.

I did manage to find a few things out... There is a place that carries the replacement, but it is just South of $300! OUCH!!!

And there is always something called a wiper relay that is like $13 at Corvette Central which may be the fix?

I've no idea at this point.

the problem with mine was the wiper delay pulse module. You can find them on ebay from time to time.

Just a little update. I got a working wiper delay module out of another 79" from a friend of a friend for 20 bucks. I am happy to report IT WORKS!!! Finally.

After installing it, initially it did not work. I ended up changing the fuse which was partially melted. That has me a bit concerned. However, it does appear to be working. I've tested it pretty extensively. So far, so good!

Where was the relay located? Might you have a picture?

Mia

Under the heater controls/radio in the center console.
See below:




FYI, you can get to it by simply removing the carpet wall (3 screws) on the drivers side. I have everything apart because I am replacing some other stuff.

When I bot my 78 the wipers didnt even work. I'm happy to have 2 speeds. Do you drive it in the rain??

Mia

I've never understood this "do you drive it in the rain" question. Of course. It's a car. There is no way to insure that you are not going to "drive it in the rain". You may leave one day expecting no rain, and then it RAINS...

People do drive cars in the rain. Corvettes do get wet.

Let me ask you this. How do you wash a Corvette? Do you use WATER???

Fiberglass does not melt.

Only bottled distilled water run thru a clear hose so that I can see if there are any foreign objects in the hose. Beer is used on the interior and it works great.

Looking to solve the old wiper module problem in my 82 and ran across your post, made me laugh. I used to keep my cars out of the rain. After doing the HotRod power tour for past two years and seeing $500,000 cars, lots of them, rolling down the back roads in the pouring rain. I think my shade tree 82 can certainly join in. JUST DRIVE!
