First need to post here after 5 years of largely trouble free driving of my 1999 R129 SL320. Anyway here is the problem:
With the roof down I raised the rollbar to remove the wind deflector. The rollbar would not retract. Tried the hold button down to reset but to no avail. Tried to raise the roof - would not work (probably a bad move in retrospect but the car was outside and it was about to rain). Ended up manually raising the roof with the rollbar up.
I still couldn't lower the rollbar so with assistance it was manually lowered. Then tried to lower the roof - the windows opened as normal, but rather than the catches releasing, the rollbar came up, at which point the operation stopped.
The roof switch is not glowing red.
I've subsequently had a Mercedes specialist look at the car, and the only fault that comes up is an open circuit on the rollbar. No fault showing on the roof operation. He's gone away to consult circuit diagrams etc.
I've looked through the forum but can't find a similar problem. I'm hoping my Mercedes man can resolve it but he's admitted he's not seen this problem before. Anyone have any ideas?
