E30 Zone

Hi i have recently bought a 320i convertible and my electric windows dont work. Does any one no the colours of the wires and what wires do what cheerz

Have you checked the fuse? It should be slot number 17, 30 amp.

I have cheked the fuse and the overload switch and they are both fine, I have taken the centre console out and on evry window swich there is 1 blue and 1 brown wire that has been cut and left not attached. cheerz

Do the windows work with the doors open ?

Had this problem with one of my old E30s - the windows stopped working with the doors shut but were fine with them open - reason being the wires which run into the doors had become damaged over time.

Wiggling these wires may get the windows working again but if it is this thats faulty you'll need to get into the loom from the A post into the door to find out where the problem is.

i will check, thanks

this is the colour scheme for the socket in the A pillar

Hi i have braught and wierd in new window plugs and cables as the old one's were shaged but still have no windows. Is there a relay or anything for them as fuse and overload switch are fine thanks

ok will do thanks

Check the switches as well, I recently found 2 out of 4 not working as they had corroded inside and the contacts were useless. Use the good switch to test the other window motors.
Seems to be a common fault on cabs
