Headlights won't turn off

Thanks Dave, I'll take it off again when I get home. I took the switch all apart and cleaned it, and checked for loose connections, but I didn't think to look for solder that weeped to another terminal. Good tip!

Just remember that those wires heat up and occasionally, the wires melt together and don't apear that way, the solder flows, the contacts over heat and melt the plastic bullets, and I've even had the bullets slip out of place apon re-assembly and not know it till I tested it. Then had to tear it apart and do it again.

When the switch is apart, pay close attention to the hole that the springs sit in. Each hole has 2 small lips that prevent the bullet from slipping out of that hole. Occasionally, one of those small lips will break off and it's so small that you don't even notice it. Then you put it back together and it'll fall apart agin and you can't figure out why.

Being as how I do this all the time, I have replacement parts and have even figured out how to melt a new lip on the hole's sidewall, to prevent bullet slippage. DON'T stretch the spring too much!! it'll cause too much strain on the lip and bullet, causing premature failure. I found that out the hard way.

If you still have problems, let me know and I'll try to help.

Dave.

So I took a look at the wiper switch solder, everything looks good. All the solder is clean, all of the connections are tight and nothing has run. No exposed wires, none of them are broken.

The 2nd pic is the relay on the passenger side thats clicking when the wipers run. I assume thats some relay, but couldn't find it in the BD catalog or at Courtesy. Is that a wiper relay, and could it be the problem? And if so, where can I get one?
