snailracer Posted November 30, 2012 Share Posted November 30, 2012 Having real problems with the wiper motor on cold and damp mornings. It won't work until the engine has been running for a while but once its working its fine. The neighbours are probably getting a bit annoyed at me sitting for five minutes with the engine revving before I go to work Its a series 3 109 with a 200tdi, recently had a new loom and has no charging problems. Anyone got any ideas? Cheers Matt Quote Link to comment Share on other sites More sharing options...
western Posted November 30, 2012 Share Posted November 30, 2012 maybe the motor needs new brushes or a good service, change the grease in the gearbox & make sure ot can move easily, the wiper wheelboxes & drive cable should be greased too.

Tanuki Posted November 30, 2012 Share Posted November 30, 2012 Is it the motor? I'd rather bet that it's either that the bundy-tube-and-wire that connects the motor to the wiper-wheelboxes is full of rust rather than grease, or that the wheelboxes themselves are seizing. The wheelboxes in particular are a spectacularly bad design: a 'monkey-metal' aluminium alloy tube that fits through the bulkhead with a steel shaft running inside it - and no way to keep it properly lubricated. Once water gets in the gap between the spindle and the outer part, electrolytic corrosion sets in and the whole lot binds up irreversibly.

Snagger Posted December 3, 2012 Share Posted December 3, 2012 It has to be the wiper, wiring or switches (don't forget the park switch on the moror's gear box). If it was the drive mechanism (spindles or cable), then they could be seized with ice in sub-zero conditions and free up when the temperature increases, but dampness being a factor suggests electrics...

snailracer Posted December 4, 2012 Author Share Posted December 4, 2012 cheers for the replies. Sounds like i need to check all the connections and drown everything in wd40 Quote Link to comment Share on other sites More sharing options...
