Windshield Wiper Gremlins

[Egan]

So, we're finally getting some rain in Kalifornia and I start having wiper issues with my 05 H2. Every once in a while the wiper would just stop working when it was on intermittent. I have a short commute so I didn't really notice it, and changing the the delay up or down a notch resolved the immediate issue.

However, this morning I had a new, weird problem. About 4 miles into my 12 mile commute, with the wipers on the slowest intermittent setting, the washer fluid sprayer came on and did not stop. The only way I could get it to stop spraying was to push the sprayer button forward and hold it there (for the next 8 miles). I even pulled over and shut off the engine for a minute without success. I kept letting off the switch every mile or so to see if it fixed itself and it wasn't until I pulled into the parking garage at work that it went back to normal operation.

I was planning to pull the washer pump fuse (assuming it's a separate fuse from the wiper motor) but looks like I won't have to.

Any idea what caused this? I'd rather replace the part now than have this happen again in the future. Any idea what part needs replacing?
