Help , Power Door Locks 87 300D

Help, I cant figure out why the power door locks on my 87 300d are not working. I just changed the vacuum pump to a working vacuum pump and and still got nothing. Could there be a leak in the vacuum thats causing this? Where do I start?

There is a connection between the pump wires and the doors etc. It is under the carpet in front of rear right passenger, almost under the front passenger seat. You need to lift the carpet hard to reach it. It is corroded due to condensation. Start by reconnecting these wires and you will see 905 of the problem solved. The rest could be a bad door vacuum element or a bad leaking vacuum connection. Hope this will help

I took out the wires and i noticed that im not gettin any power through the plug with my tester. I lifted up the carpet and looked like it was taped all the way to the front of the passenger seat. I lifted up the carpet and saw a whole mess of wieres half of them were going to the becker audio. There was a wire that was green/brown/yellow that was cut?? anyone know what those wires are for? Still cant get power door locks to work , no power coming from the wires.

follow thw wires coming from the vacuum pump, they should go to the direction of the radio. if they are the free ones, then your system was disconnected.

Fuse was checked , fuse is properly good...

Just cant figure out why the power door locks dont have power on the red and brown wire?? I dont have the becker radio, some one stole it like 15 years ago so my dad had some one put in another radio and the whole radio is ghetto rigged. What would happen if i took out the becker audio equipment thats on the bottem of the front passenger seat. This whole car electrical system is a headache, does anyone have a diagram for it 1987 300D Turbo
