I've been having a problem with my windshield wiper. On intermittent it might go once, or 5 times and then stop wherever it wanted. It may not stop at the stops, or it may not go at all.
On "low" or "high" it worked fine.
I *assumed* it was the switch in the stalk.
If the headlights were on, and the wipers as well, and I used the turn signal, it *MAY* light the left turn signal indicator on the dashboard (not the outside, just the dash).
I'll reiterate, I assumed it was the switch in the stalk. I was ready to pull the steering wheel, pull the switch, replace it with a new one ($50 at AutoZone), and be done with it.
I was wrong.
Backing up, I read here some time back that rust sometimes forms under the windshield, and you may wanna drop the windshield from time to time to clean/treat the area. Well, my windshield bolts were (and are!) stuck fast, but I also read that you can take the roll bar attachments loose from the main rollbar and drop the whole thing. That took some "tapping" and some brute force, but I got it down. Almost no rust down there, and not too bad to drop, either! (I'm not too worried about the bolts at the windshield frame, as I don't expect to drop the windshield very often)
While there, I took a look at the wiper motor. The wiper motor cover is held on by three small bolts. Two had rattled loose and fell into the cavity below the motor. The last one held the ground wires. Two of them, to be exact, and it was loose, too.
I found the missing bolts, dropped some blue Loctite on them, tightened them up, removed the remaining loose bolt, dropped some Loctite on it, and tightened it up, reassembled the whole thing, and to my surprise, ALL the wiper, turn signal, and headlight problems are GONE!
Sometimes it's the simplest of things that make the most sense.... so if your wipers are acting up, before ya get all tied up into the steering wheel and the guts underneath, check this first.
Just a thought!
