560 door lock

no3withacoke · 04-22-2009, 11:13 PM

I'm new to this site, so hello all--

I have a 86 560sel with low miles and i used to drive a 83 300sd, bought brand new.

I have a couple questions:

1. Sometimes when i unlock my 560 from the driver's door, usually when getting out, the other door locks won't pop up.

2. If I unlock the driver's door and decide to relock it again, I can feel vacuum pressure in the mechanism that won't let me press down the button.

These symptoms never occurred on the 300sd. Is something wrong with the 560's central locking? Is the central locking from 86 different from the 83, (beside the three point lock)? Thanks in advance!

Lube the links from the vacuum motors in the doors with white lithium grease or spray. Lubriplate is my favorite. The anti-lockdown feature eliminates the Oh Crap Lockout keys in the car events.
