Headlight Washer & Heated Mirror Questions

[Traurig, Scott R]

OK, here's where we stand on this subject...

** Heated mirrors: mystery semi-solved.

I do have the winter package (heated seats, etc.) We don't know the actual
temperature at which they activate, but list consensus is you can't feel
them, so I just need to keep an eye on them and see if the frost melts in
the winter when they are frosty.

** Headlight washers: truly broken, and the mystery deepens.

Truly broken I'm afraid. I only just ordered the factory manual (on CD-ugh,
paper is no longer available-ugh!) and wiring schematics today, so any help
would truly be appreciated. Here are the symptoms and diagnostics so far:

	All fuses (#3 and #24 if memory serves) are good. With plenty of
fluid and the lights on, of course :-), when I pull the wiper stalk switch

1.	The windshield sprayers spray and wipers wipe
2.	One second after that a relay clicks on and voltage appears at the
terminals of the headlight washer motor.
3.	One second after that the relay clicks off and there is no voltage
at the terminals of the headlight washer motor. 2 & 3 happen whether or not
the headlight washer motor is hooked up.
4.	Attaching the headlight washer motor directly to the battery nothing
happens. The motor coil measures 1.8 ohms.

If the motor is bad, would that kill the relay? I wouldn't think so. I
assume the headlight washer relay should stay energized from 1 second after
the windshield sprayers start until the stalk switch is released. Why is it
going off after 1 second? Perhaps I have two separate problems, the motor
and the relay? Maybe a good starting place is the relay. Which relay is it,
and how does the manual say to test it?

Thanks, this list is great.
