Passenger Door Motor - Bouncing Up

Hello!

I have a problem with me passenger door lock. I had a toad Ai606 fitted yesterday, this problem was always there but the fitter could not sort it out, even with all these different wiring methods.

The problem has always been there since I have had the car, when you press the lock button inside the car, both doors lock, but then the passenger door unlocks. He told me that when the locks get a longer pulse, the passenger motor throws a wobbly! Has anybody had this problem with their locks? I need to sort it otherwise my full closure will not work properly and it will just be poo!!

Thanks,

Irfan
