Hi.
Usually I can operate the elec. seats when the key is off and the door is open, but today after I took of the negative battery pool for two hours, the seats can now only be operate when the key is turn all the way to the right or when the car is running.

Someone knows what happened?

Hello secret Scandinaivan, nice to see others from the best part of the world. :-)

OK, now I recall your cars. :-)

I've never had this problem, but my immediate thoughts goes to a bad contact on the door light switch. I guess that triggers the circuit for the seats and windows to work when the doors are open. But if so, then the interior light shouldn't work either.

Cheers

OK Bing, let's include UK along with Scandinavia - you know the roots back to the Vikings, we have a lot in common. :-)

Hi.
I just called an expert and he said it must have something to do with the comfort relay (white). He will have a look at it next week.

Funny. This car has been in UK from 1997 to 2009 and I bought it from Charles Ironside ltd.

Comfort relay?!?
(Another electrical unit to maintain, WTF!)

However, keep us posted on the solution. Thanks. :-)

The seats have nothing to do with the convenience relay (I assume that's what he meant by 'comfort' relay)... this affects the windows and locks, not the seats.

There is a diode that plugs in the rear of the fuse box with the other relays, that is related to seat operation with the key off. I'd check into that.
