Doors don't open

[Klaus]

I run a 4.2 in Berlin, Germany (next dealer - one out of two - about 300 miles away). A problem with the doors keeps recurring: Usually they work fine, as does the alarm, but sometimes they won't open (except manually). On the previous occasions the fault has righted itself after some time, but not this time. I have to leave the window open to get access to the car, and it's snowing outside... Not really practical. Anyone got a clue? I'd really appreciate any infos - thanks.

The car's a '98, so it should have a magnetic switch. Thanks a lot for the info, I will give it a try tonight.

Merry Christmas
