'89 240... power window problem

In the 3 years I've owned my '89 240 wagon, the right front (passenger)
power window has never worked right. I can use the driver's side switches to
lower and raise the other 3 windows, but I can't get the Right Front window
to lower unless I use the switch on that door. Interestingly, I can use my
driver-door switch to raise that window, just not lower it. I've checked to
see that the connectors are attached, and even sprayed a little contact
cleaner into the switches to try and fix it, but no go. I'm guessing there
may be a broken wire, or perhaps a relay? Anyone know what would be the most
likely cause, and what I could do (cheaply) to fix it???

The most common failure is the switch itself.

 

All the switches are the same. Grab one of the switches on a rear door,
unplug the suspect switch from the front door harness and try the rear
door switch in it's place.

Replace tt with t (twice!) and remove parentheses to email me directly.

Thanks! I didn't expect them to be the same, very convenient if one fails on
the road!!! I just replaced the defective driver-side switch with one from a
local junkyard, works fine. Wish I had tried that 3 years ago!

Happened to me on our 340 and 740. Easy to repair.

Remove switch, pull switch apart but do this sloley as it contains a metal
rocker with contacts on, two balls and two springs. Clean the contacts on
the rocker bar and the corresponding areas and reassemble.

Volvo usually try and sell U a new switch for silly money - but then if
volvo fix for you it is probably cheaper forking out for new switch than
having them spend time fiddling with a repair.
