My guess would be the switch. Sometimes they call that a "multi function switch" because it also controls the turn signals and your 4-ways. It is easy to change, IIRC just pop out the ignition key switch, take off the upper and lower shrouds and it's right there. Pull the negative cable b-4 you start and wait 5 minutes....you are in air bag territory. New ones are in the $45-50 range and salvage yard around $15...(in my area). Good Luck.

Intermittent wipers went squiffy on my '98 XLT. All the intermittent positions usually gave one sweep of the wipers. The low constant speed position gave 1 intermittent speed & the high constant position gave constant wiper action.
The GEM module was suspected. This Black Box is deeply buried behind dash left knee panel, a PITA to R&R.
Was going to try to find replacement at U-Pull junkyard, but just the probing, jiggling & attempt to check if wires going to GEM were snug, in place, restored proper functioning.
Wipers have never hiccuped again.

Suspect if was as EZ as "the switch needs cleaned of dust" you'd be able to just wiggle the switch & get it to work. Especially if you have intermittent "worked off and on" issue.
My TIP about "jiggling" the wires going to the GEM apparently restored a loose connection.
My wiper problem was intermittent, as in not all the time. Sometimes the delay positions worked fine, for weeks. Then there were no delay speeds. Some times on same trip it "worked off and on".
Since I "jiggled" the GEM wires it never happened again. That's like 2 years ago.
