Intermittent wiper issue

Intermittent wipers, as well as low and high worked fine. Now, when I use the intermittent wipers, they are always on the low setting. Low and high still work fine. Just on the intermittent do I have an issue. Is this the module for the intermittent pulse?

I've had the issue, turns out it was the signal switch itself going bad. Replaced and haven't had issues since.

Hansen13, what do you mean by the signal switch? The turn signal switch, or the wipe switch/****?

ahhh **** guess should have asked what year your truck was. the 92-97s had the signal switch/wiper on one control and they tend to fail.

What year truck? At least through '91, the wiper module is known to fail. Located under dash, near parking brake, plastic box maybe 2" cube. Apparently, vibration from brake release eventually cracks circuit board. Happened to my '91, and the '86 parts truck had the same module.

OOPS, my bad. 1991 F-250. I know they have the module, was wondering if this is an indication it is bad?

I have '88 F250. The wiper uses the low speed setting to do the PARK function when you turn them off, because that's where the electrical contacts in the wiper are. The intermittent circuitry uses a timed power surge to start the low speed circuit, which then goes to PARK since the power has shut off. So I don't see how the intermittent could ever do high-speed.
