84 300D a/c vents not working
My 1984 300 turbo d (new to me) blows cold air out of the wind shield defrost. Nothing out of the center vents and yes the're turned on. Is this a vacuum issue or a servo issue? In either case where do I look for vauum leak? I had the under the dash panel off and there are 2 (that I can see) pretty pink plastic things. Would those be the servos?
Any advise would be helpful
Thanks

1985 300D Turbo, CA mod. w/ trap oxidizer: vacuum line connection
After doing some engine work, I could not get the engine to shut off. I checked all the vacuum lines and connections, which were ok, including testing the fuel shutoff valve and checking the line to it for grease (none). From previous testing, I know that the vacuum pump works well. I thoroughly studied the "Vacuum System Troubleshooting" manual. I noticed that there is one black vacuum line which remains unconnected, the one with a damper from the vacuum transducer which supposedly goes to the automatic transmission vacuum modulator. When I plug this line with my finger, the engine stops.

85 300SD rear end ratio
I want to maximize my diesel economy. Is the rear end ratio in a, say, 560 SEL of that vintage interchangeable with the rear end on my 85 300SD ? What are the two respective rear end ratios? Thanks so much!

1984 300D STARTING PROBLEM
Hi,
Sometimes my diesel engine will not crank. I recently put in a new ground strap, starter, alternator, and battery in the last year. All appear to help for a while and then it happens again. Is this common?
Thanks,

Just bought the xenon bulbs from the source. Would like to know if there is a trick to removing the front dome to change the bulb?

84 300D Front suspension is lower than rear ??
My 123 sedan has an unusual look in that the rear suspension is higher than the front similar to what people try to achieve with sports cars. Is this typical? Can this be just worn out shocks or are springs fatigued?

89 560sl light indicator on after brake pedal pressed
The dashboard light indicator comes on after pressing the brake pedal the first time after starting up. I've checked bulbs and all work but am not sure if they are the correct p/n. All have nickel/silver bases which I understand they should be as I was told the copper/gold bases run hot and tend to fool the light module into turning on the indicator. I just recently got this vehicle and it appears the previous owner had a problem with the 3rd brake light as it has been resoldered and has a broken holder. It functions but I am not sure it has the correct bulb installed.
