The high and low steady speeds work all the time when turned to that position....intermittent setting does not. If you turn it to intermittent it wipes once and stops..kick it up a notch or down a notch..works once and stops. Yesterday came on all by itself and washed the windshield 2 or 3 times by itself. Simply you have lo and hi speeds...no intermittent.

2007 Chevrolet Suburban 1500 Question: problem with intermittent wipers

good question.multifuntion switch if installed on your vehicle would need cleaned with electrical contact spray,otherwise it would be the wiper motor pulse board module and it would be cheaper to replace the wiper moter completely as the wiper motor pulse board module is allready in it.
