Puzzling Short: '93 940 Wagon 900

Hi Spook,

It's hard to see how the headlight switch can run front and rear wipers,
and this is a single connected problem. They're on separate fused circuits.

Is your washer pump buzzing too when this happens?
You can isolate the problem some more by removing:
Fuse 15 front wipers
Fuse 14 Tailgate wiper

The circuit diagram shows 3/12 as the front wiper switch
with an intermittent relay 2/4
There's a an inset showing interconnected junctions for the wiper stalk
switch in 5 different positions. You could check with ohmmeter
and 3/13 as the tailgate switch
with an intermittent relay 2/16

Firewall connector C2 is in series with all this stuff, you could eyeball
the harness to see if it looks healthy. I would not unplug it.
You could easily get in the soup and have a big job on your hands.

Amarin, Does the bracket between the high firewall and the strut stud
(that the connectors including C2 are tie wrapped to) do they get released
by just removing the nut from the rear strut stud?

I'm in the middle of repairing the OBD port A & B with the silicone support
for the female pins fragmented and only a few recognizable pieces left in the
collection of debris that fell out. Dave Barton has the parts needed to fix.

The OBD port has bullet connector style pins. Beware taking them apart
since you may be stuck reassembling them. The RSR has this style connector
so there's a landmine to know about.

Amarin, Brickboard mail is kaput, how do I e-mail you with off topic music stuff?

Bill
