Replacing the wiper/washer switch, but I’ll be damned if I can remember if it had intermittent wipers or just lo hi and mist. It has a chrome handle, but the letters have been worn off for years. It is a Scottsdale, tilt column but I cruise if that helps. Thanks fellas!

Not sure if that would be in the RPO codes, someone more knowledgeable in that might be able to tell us.

What I would do, is even though you have the wiper switch removed, I'd take and put the stalk back in and move it though the positions. If it's got 3 stops plus mist then no intermittent. If it's got 4 stops and one has a bigger amount of movement in it then it has intermittent.

Search for the pulse wiper module under the dash next to the wiper switch. If you find one the truck was equipped with intermittent wipers. If it still works is a different thing.

Searching the forum is always a great idea.

Count the wires on your switch, I think a standard hi lo has 5 wires and the intermittent one has seven.
