I am having some problems with my 82 300sd. it"s a solid car my family just got but well:

1. the central locking system isn't working the vacuum and switch works. There is a leak somewhere. Anyone know got a guess.

2. my power antenna does not work either.

can I get line from any loyal w126 fans

3. the power seat come on and off. the flexible shaft slide too far to one end and does not engae the other side.

 

follow the leak and find out

maybe the plastic gear strip is broken. replace it.

 

do you know where the basic route and where the connectors are? I am going to remove the front seats to look under the carpet.

 

give me the VIN and tell me which diagram you want.
