E34 520i central locking and electric window problem

[jonnie]

Hi Guys,

A friend advised me to come to you guys as your bloody helpful!!

Recently got a E34 520i, but have a problem with the central locking and electric windows. They only work 105 of the time and I have to leave the car unlocked in my garage at the mo, as I can;t trust that it will open. Doesn't have a fancy alarm, just uses the key for the central locking.

I reckon they must bith be connected and probably is down to a bad earth, anybody got any pointers???

Thanks
JC

The central locking and windows run through one big plug by the door hinges, check it's not loose or corroded.

I would say loose connection somewhere, I'd check plug as Greeny says, does it work from passenger side front door?
