After m50 conversion no electric windows???

[MOODY]

Hi there all.

Jus done a m50 conversion to a e30 320i 1991 it's up and running but the electric windows don't work, they only wok when you open the doors fully and ideas to what needs doing

[Ant]

unloader relay feed from the starter is missing or broken I'd suggest.

Its there to kill the e/winds and blower motor etc when the starter is engaged

common fault !

[MOODY]

So you saying a relay needs replacing? If so where is it located thanks

[Brianmoooore]

Relays are likely to be fine. Chances are you haven't wired the starter motor correctly.
Do the heater fan and door mirrors work? If so, check fuse 17.

[MOODY]

How do I have to wire the starter then, the top of the starter has 2 thin wires and the bottom a thick one, fuse is ok and mirrors don't work

[Brianmoooore]

What do you have connected to pin 15 of your engine loom plug?

[MOODY]

I will take a look 2morro dans done me the loom can't see there be a issue there

[Brianmoooore]

What flywheel/starter motor have you used?

[MOODY]

It's m20 flywheel lightened and m20 2.5 starter

[Brianmoooore]

It's m20 flywheel lightened and m20 2.5 starter

Facelift or pre?

You could try connect pin 15 of the c101 to earth.

[MOODY]

Nothing it is empty the car loom side it's a green and black wire

[turk]

try putting a jumper cable from pin 15 to earth. that should do it...

[MOODY]

Just tried it no joy

[Brianmoooore]

There should be a green/black wire running from pin 15 to the smallest terminal post on your starter motor.
Earthing pin 15 as a test should make things work as a test though.

[MOODY]

There is a green/Blk wire it's the car side on the plug and when I've earthed that there's no difference

[Brianmoooore]

If there's nothing connected to pin 15 of the engine loom, then you shouldn't have a heater fan or door mirrors either. Something odd here!
Are relays K5 and K7 in place in the fusebox?
Pull out K5 and link together pins 30 and 87 of its base with a piece of wire and try the windows.

No mention of heater fan!
