Possessed Wipers Please Help!

[Mistersponge]

Ok, heres the low-down; 88 S-10 Blazer 165k miles 2.8L V6.
Heres the problem: Up until a few months ago, about a third of the time I would activate the turning signal the wipers would kick in for a quick trip across the windshield.

I never had a problem with this until recently. Now, I will be cruising down the road and the wipers will decide that the windshield is dirty...and help me out with a quick dust off.

The wipers function beautifully when I swtich them on. If anyone has any idea what this could be let me know please! Otherwise let me know your possessed car experiences.

sound like the wire is broken off in the turn signal arm, Happened on my 89. Had to break down the colume and pull the switch. Because the wire was shortened a little to do the repair, ensure there is enough slack to make up for it. I ended up replacing the turn signal arm becuase it broke off again. Had to do the same job twice :-(

I have an '88 S10 Blazer with the same exact condition. It started out being triggered by the turn signal on occasion and then progressed to the point where the wipers would take a trip just to let me know they were still there waiting to do there their job. A friend was riding with me one day and noticed the condition. He commented that a mutual friend's Blazer does the same thing. It appears that this is not a rare thing so don't feel that it is a bad karma event. I have learned to live with it. When we get old our little quirks make us who we are and I consider it to be a quirk, not harmful, just a bit annoying. In the grand scheme of things it is not a big deal. I've been driving with it for about 4 years now. Sometimes it won't happen for weeks and then swipe, here they come steaking across the windshield for no apparent reason. I would like to fix it but don't really want to tear into the column if I am not certain that is where the prolem lies. Good luck in fixing it. If you do, please let me know what the secret is. And if I get bored and decide to investigate more on my end, I will defintely fill you in.

My '90 Blazer has had the same issue. From what I've been able to determine, the turn signal arm on the S-10 series is prone to breaking and minor shorts like this (I also had to stop using my cruise control because it kept blowing the fuses for the main instrument console...when the majority of your driving is one the freeway, it's very unsettling to have no idea how fast you're going or how much fuel you have left!)

I'm replacing the turn signal arm (as soon as the replacement part gets here...) I expect this to resolve the problem. It's a priority at this point, because the arm is really broken...the wiper/cruise switch assembly is dangling from the rest of the arm by the wires. Hopefully, the replacement is a little more durable (of course, I'm pushing 270k miles, so durability is a relative question...)
