Wiper motor tip.

Had to remove the wiper motor yesterday and getting the trim over the wiper
spindles back on was a pig. You just can't get the windscreen rubber seal to
come back over the top of the trim. As it goes on one end it pops off the
other.
Then, almost by accident, I discovered the easy way:

Bolt the trim back on with the rubber *under* the trim, then pop a rounded
object like a Philips screwdriver under one end of the rubber and lift as
you slide it along. Easy peasy.
Hope this helps anyone in the same boat!

...... me too, but it was the rear one (1997 300 Tdi Disco)

My top tip:

The rear-wiper does not work if the driver's door is open. Most
infuriating if you've spent all day carefully removing the rear-door
trim and cleaning up a seized wiper mechanism then the chuffing thing
still doesn't work........ until you shut the door and drive off!

I've found loads of references to this in afl ....... but only
afterwards.

Cool! Didn't know that. Useful.

Also had a problem with the door locking, the button kept popping back up on
locking it. Discovered that by moving the motor just an eigth of an inch on
it's mounting plate cured the trouble. I was chuffed!

ours does that on the driver's door, must have a look at it. it's caused by
a mis-lock, which causes it to unlock again, so it might simply be that it's
not engaging quite fully, hence moving the motor. The back door on our
disco seems to go "BRRRRRAP" rather than just "KADUNK" when it
locks/unlocks, but it's still working.

Another "gotcha" on the 300-series discos: the electric window system has a
cunning feature that for about 45s after you off the ignition the windows
will still operate, which is dead handy when you pull up, switch off and
then go "oh ****, I forgot to up the windows". However, opening the
driver's door cancels this 45s thing. This is designed into it, for no
obviously good reason, but can lead to much headscratching about why it
sometimes works and sometimes doesn't.

it might do - gotta investigate the absence of self-parking on the disco
here one day.

It wouldn't make any difference on the Disco but it's the same on RRC and if
it worked with the rear flap open it would mangle the wiper arm. They
probably use the same ecu and wiring though and that's why. It's controlled
by the interior lamps.

When mine sometimes doesn't work, the rear door windows don't work either,
but if I take out the cubby box tray and wriggle the plug on the ecu under
there then it works for a while. Must get around to sorting it someday!

ah, that's a different one, if it's a 300 TDi disco there's a known issue
with the window ECU.

see
http://www.discoweb.org/window/index.htm

for how to fix it - did this on ours and it's worked fine ever since.

That's pretty much what mine is doing Austin. The intermittant works for
about a third of it's intended travel, which is fun, and the park doesn't
work at all. The motor appears to be well sealed and the realay seems OK so
I'm stumped. Bet they'll say it needs a new motor....

ours goes across to the other side of the screen and stops.

it'll be the parking switch, which on older motors you could unscrew and
change. Yet to investigate, mind, but that's what I'll bet on. and yes, I
daresay it'll be new motor time. Or vandalise motor and invent new parking
switch time.

Think you might need an angle grinder to get into the motor itself. Mine
appears to be a sealed unit.....

I think there is a complete analysis if this problem with the intermittent
on the DiscoWeb. A fellow completely dismantled the motor to see how the
system works. Basically wiper-type electrical contacts on a rotating disc.
Grease could foul the contacts or they could break. He also said that the
separate ground lead from the wiper to the car body was absolutely necessary
to get the intermittent to work. Unfortunately cleaning and reconnecting
the ground strap didn't solve my problem.
Not fussy about dismantling the wiper motor as wiper are pretty necessary
around here at any given time.
