R129 (92SL500) Wiper Failure, ABS and Roll bar light

[deansy]

Hi Guys,

I've been experiencing a few electrical (?) problems lately - and wondered if anyone could provide some help.

The wiper on my 92 SL500 has developed a problem whereby it stops working completely intermittently. When this happens I can't also flash the lights of the car by pulling back on the control stalk that operates the wiper and the full beam/flash headlights. At random this then comes back on. Also, the roll bar light keeps flashing on and off. I have also had the ABS light coming on when driving above about 50mph on the motorway - it stays on but if I restart the car it clears, only to come back on later.

Is the wiper/flash lights issue to do with the control stalk? Relay? Or something more serious like the wiring loom? I've had a look at the forum for ideas on all of these issues but wondered if they are all related. I am also worried that it may be a wiring loom issue as apparently the early SL (R129) suffered from this problem.

Any help would be greatly appreciated.

The wiper/flash problem does indeed sound like the column stalk - mine won't flash at the moment, so I'm waiting on a new stalk as my mechanic checked the relay and its fine - thank God, because they aren't cheap (stalk is just over a ton).

Regarding the ABs light, I don't know. Roll bar sounds like a dodgy sensor.

I think the wiring loom issues affected the early 129s?

Get your car to a dealer or a decent indie and get it checked out, particularly with autumn upon us - you don't want to be stuck with no wipers....

Cheers,
Greg

Ditto...our wiper functions are now reduced to "all or nothing", only the fast speed and washer jets remain, although lights are unaffected. New stalk arriving mid-week, which should hopefully cure the problem.
