Hello. Need your help. With my Calibra 16 V , year 91 , the following problem has arisen. Window lifter by the driver side without function. Is also no click or any other noise to hear. Thought of switch or engine defective. But exterior mirror adjustment passenger side is also without function. ZV works. Speaker also. What can be that. Mass problem ? Plug / cable apart. What can this be about. Driver side everything. Also mirror adjustment and window lifter. Had before a a few months a lot screwed on the car. Can I have accidentally pulled a plug apart? If so, where? Where on the door wire harness would be such plugs. How would you proceed? Have looked for security. everything in order. Please help me.
