Astra h Sri 2007 1.6T

Hi, the car runs fine until trying to use front window wiper, when you press it the clocks go off/ keep flickering and the engine cuts out
Also any beeps/indicator/locking or unlocking car causes front wipers to move slightly.

Tried removing window wiper motor to see if that was the problem, then car will not start without it connected?

Anyone experienced similar or anyone got any suggestions?
