Re: Intermittent electrical stuff

More than likely it is dirty connections. Fiddling with the mirror 
switch by moving it over time probably rubbed the oxidation off of 
the internal contacts. I never used any type of deoxidation compound 
on electrical connections to clean them. But ones that do work well 
are rubbing the contacts with a pencil eraser, and "washing" them 
with a solution of 50/50 (or slightly higher) mixture of distilled 
water and isopropyl rubbing alcohol. That and of course 
unplugging/plugging back in electrical connections to rub any 
oxidation/dirt off.

As for the mirror switch, it's possibly either a loose connection on 
the harness plug, or there is the possibility that it may be bad 
internals. The only way to check this is to pull the switch, then 
reseat the switch plug back into the harness (cleaning connections if 
nessisary) and see if the mirrors work after that. If not, use a 
voltmeter, and check for a good electrical connection thru all 
positions of the switch. For a wiring diagram on the mirror switch, 
see here:

Other than that, just be gentle when prying the switch out. Push in 
the clips on the sides, and lift it out. If you pull too hard on the 
top of the switch, it can come apart. And then you definatly will 
need to buy a new one.

intermittent window switch--sometimes it works in all four 
directions, otherwise it will only move mirrors up and down.
