1985 300TD Fuse 14 blowing

Fuse #14 keeps blowing. Here are the electrical issues I've noticed:

1. The car will only start in neutral.
2. The glow plug buzzer does not go on (but the glow plug light works).
3. After the buzzer stops working the AC blows hot only.

Fuse #14 certainly could impact the AC because according to the fuse diagram it controls "control unit/water pump/heating water valve for climate control system.....". But what about the neutral safety switch and the glow plug buzzer?

85 300TD Rear Axle Interchangeability ??

I have an 85 300td that is in need of new axles. My car has the Homokinetic Axles that have the "can" on each end where both ends of the axles look similar.

A friend of mine gave me a new set of Annular type Axles with 6 or so bolts on one end.

Are these axles interchangeable without any modification?

1980 300D - Moving to the "Rust Belt"?

My family is preparing to move to Delaware from Oklahoma. As I understand it, Delaware is in the "Rust Belt." I'm wondering if there's anything I can do to prevent rust problems before they happen. Any suggestions would be much appreciated.

Thanks!

85 300TD A/C belt keeps coming loose.

I'm having an issue with my A/C compressor belt on my 85 300td. It keeps coming loose.

When I bought the car 2 months ago, the belt was missing completely and I was not sure if the A/C worked or not. I installed a new conti belt. The a/c works perfectly except after 200 miles or so the belt comes loose. Yesterday I checked the belt and now it looks slightly chewed up on one side.

I'm not sure if the problem is A/C pulley or something else.

1982 300DT vacuum troubleshooting

I recently purchased the Vacuum Troubleshooting kit and have begun to tackle some minor issues with my wagon.
Right off the bat I find something not specified in your manual.
I started with a vacuum pump test and my gauge is reading 16.5 inHG. When I remove the line from the booster it reads 19 inHG - neither seems REALLY low, but are below the 20-23 inch range.

I have two questions:

1. Is there a way to determine if my checkvalve is leaking versus a slow leak in the pump itself?
