Hello all,
I'm having a problem here. I had a vacuum leak in the door locks on my 85 300d. I started ripping the doors apart and testing everything. I discovered that my passenger front door has been replaced and repainted. The inside of the door was blue. Anyway, the vacuum actuator in the door to operate the locks is the older style with the 2 rubber diaphragms on the top and bottom and the plastic in the middle is blue. From what I have seen these actuators should be on cars from 1980 and earlier. The 85 is supposed to have a black plastic kind. I am wondering if I can just take the old one out and put the new one in. anyone have experience in this? Here are some pics of both actuators.
