Locked Door Fix

I unscrewed the door lock button from a rear door and heard this terrible noise... the clinking of something falling down into the door. Now it seems obvious that the threaded rod that initiates the lock/unlock mechanism has fallen into the door. The problem is the door is locked and I am unsure as to how to get the door panel off to fix this. Can the lock be picked by a rookie or am I going to have to get a locksmith to open it? Why would it fall into the door unless it is not attached? Any ideas would be appreciated.

Seat not moving & window motor whirring

Just started digging into my brand new 1984 300SD to fix a few essential items; I was told the driver's side seat worked, just needed a new switch. So I ordered a new (used) seat switch and hooked it up and still no action. Any advice on where to go next? Also was attempting to fix my driver's side window... which is turning out to be quite a challenge. The motor works, however, the big drive gear just spins on there.

'85 300TD charging system

Hello, I suspect I have a charging deficiency in my '85 300TD(230K miles). To-date I have replaced the brushes/regulator, belts, replaced dash light and cleaned bulb holder. Voltmeter testing at the battery shows 12.5 vdc at idle, 13.5 vdc at 3-4K rpm. The dash light will not light at all, but shows continuity from the multi-pin connector across the bulb circuit with holder in place. As far as symptoms go: I occasionally (once every six months or year) find that the battery is low and will not turn the starter. The climate control system does not react to any setting less than full on or full off and the heater motor takes a few minutes of driving to start blowing.

81 240D 3 Water Pumps In 6 Months

Hi--- I have an '81 240D fitted with the 2-tank Greasecar system. Don't do too much of my own work, but I'm using the 75 MPH Guide to keep Anna happy and healthy. So far, so good... but, I've gone through 3 water pumps in less than 10,000 miles. The 1st was the original, so I new that would happen. And it did at exactly 120,000. Had it replaced with a Bosch, which promptly failed. Had it replaced again with a German pump, the name eludes me. Well, this pump also failed and I'm having it replaced with a Mercedes pump. Fortunately, this is all warranty work.

You have to love these cars to do what we do and your commitment shines! Now...suggestion..the special tool that you offer for the removal of the 103 water pump is a godsend. you might however offer the tool with this stipulation...PAY ME WHAT IT IS WORTH AFTER YOU USE IT..you might be amazed at the return on that concept!!!
