ANY IDEAS? Elec window went up and stayed up.

Well that's good to hear. Let's hope I am suffering from the exact same thing. I have some new drilled rotors I wanted to put on this weekend, and sure didn't want to bother with tracing electrical problems. I HATE electrical problems!

Here's a follow-up after inspecting the door: it was indeed the switch (on the passenger side) that caused the issue.

That said, I had also decided to take the door panel off to see how the mechanism looks. (Remember it was going down slowly) Glad I did. The joints, tracks, and pivot points were sorely in need of lubrication. In addition, much of the U-shaped metal track, including the metal that grips the bottom of the glass were encrusted in a white powdery efflorescence-like substance -- almost like what you see on a bad battery.

I took the time to clean and lubricate everything. Everything works great. Now I suppose I had better do the driver's side as well.

This car has been in San Diego (i.e., dry climate) it's entire life, so I can't imagine what a similar car would look like if it's been in a lot of rain. If you live with rain, you may want to check yours out some time.

Even though San Diego is a dry climate, you do have the salt from the ocean. That could be the cause of the efflorescence.

Sounds good, but no, that isn't it. The air isn't that salty here unless you live ON the beach. I live one mile from it and on a hill, and if that were the case, everything else I own of a similar nature would be in a similar state. Nothing else is.

I suspect it's more that moisture gets down inside the door and there is not enough air movement/convection to dry things out in a timely manner. Since we like to keep our cars nice and shiny, and stored inside garages and out of the sun's warming effect, this may be something to think about.

Or not.
