Hello forum, nice to be back on the BMW scene, this time with an E30 which has a small strange problem.

Problem is like this :
If I try to activate the windshield washer nothing happens.
I changed the pump for the washer as I thought it is defective.

New pump installed... same thing.. activate washer ...nothing happens AND the wipers don't move.
Connected a voltmeter to check voltage ... activate the washer and I can see 12V and the wipers also start moving.
Connected a simple light bulb 12V to see if that works, activate washer, nothing happens, no light , wipers don't move.

As soon as I only connect the voltmeter to the wires for the washer pump .. I can see 12V and the wipers also start moving.

Is the car measuring consumption and can not pull the whole thing ?
Anyone else seen this problem ?

Any ideas would be appreciated.

Thanks in advance.
