ok we have an 85 elky it has the CD4 intermittent wipers with the circuit board module on it 22038486

if you run the motor alone on a battery on the bench both low and hi work fine and it sounds nice

yet on the car all assembled the motor doesnt act right

how can you determine what is wrong and where can you find another module like this ?

no yards here are any help

any tips would be great

thanks

If assembled back on the car, the wipers will work on the intermittent setting sometimes, sometimes not- and the switch detents don't seem to have an exact or repeatable effect on the wiper delay, it's prob the switch portion of it. At least that's been my experience in the past.

The switch can sometimes be brought back by spraying it out w/electrical contact cleaner REAL good (Radio Shack carries it, can't use carb cleaner, etc.- will damage some plastics).

If there's NO intermittent action, regardless of switch position (jiggling, setting half way between detents, etc.) then the CB/module circuitry could be bad.

I'm not sure what you have going on, though- are the wipers OK in "regular" low and high, etc., but not working on intermittent?
