Been told today that I am likely to need a complete overhaul of my wiper motor and mechanism (including the spindles). They leak (wondered where the water came from) and doing this necessitates pulling the dash. Oh, and being a right hooker, parts are not exactly falling off trees
Lovely :(

Ouch. Perhaps you can do a lot of the prep work (the actual dismantling and re-installing of the dash components) yourself?

Tosh,
It's a pain of a job to do. The motor is an easy job as it is removed from the engine compartment. You may have more difficulty getting to it because of the brake booster. The spindles are a challenge. I question if the leak is coming from the spindle and wiper shaft itself. More than likely the leak is coming from the spindle to body area. Looks like a rubber washer is installed against the body around the spindle. If the washer has dried up and cracked there would be a leak problem possible. The way the wiper shaft is installed through the spindle, water would need to go uphill so to speak to come in along the shaft.

Actually on a RHD car the booster is not in the way. There is plenty of room to get the motor outr. I agree with Jeff though and check those rubber washers first !

You might also check the condition of the scuttle box drain tubes. There is a rubber hose on each side that connects the upper and lower metal pipes, and if the rubber hoses are rotten you can get a leak there that might mimic leaking wiper shafts.

I agree w/both G and J .
Check the drain connector hoses under the dash [ both sides] and the body seal/washers around the spindles. The spindles are in a body cavity so a bad washer will leak into the cabin and the hoses commonly dry up and crack. I replace these with clear hose so you can easily see if they plug up with debris without having to pull anything apart at the air intake vent assembly..
..also, check the one way ball valves at the end of the drain hose pipes [ on firewall]

Wow, this place is amazing! Thanks
I will have a poke around. Haynes appears to be as clear as mud so I'll find an hour, some daylight and a flashlight. The estimate to replace the lot is not small so anything I can do to prolong active life, the better
Had an advisory on the certificate of roadworthiness/MOT and had a worn left kingpin (front) resulting in excess lift so that was shimmed rather than replaced. Other than that... good to go for another year, the 37th...

Isn't water from around the recessed area where the wiper arms attach (shaft?) supposed to drain into the box and out the rubber hoses mentioned here? I recall that a gap should be found at the lower rear coners of the cowl vent cover. If that gap is plugged, it can lead to troubles. I'll look and post a picture of what I'm thinking about.
