Window Alignment

Today I was at the Merc shop to finish off the door alignment project.

We fine tuned the door, aligned the window, moved the window "stopper", and did not manage to get a perfect fit. It was better than before but still not completely frictionless as the door should be.

We were stumped, and then paid close attention to the passenger side door for reference. It appeared to bulge outwards a millimeter or two, whereas the driver's door actually caved inside. I had the idea to have him move the door lock mechanism at the "B pillar" side outwards maybe 3 millimeters and voila, door now closes very well with the window up.

I went for a short test drive and concluded that the adjustments we made to the glass resulted in a loss of seal. Once we undid that bit, the door and window work better than they have ever done while I've had the car, maybe even better than in the C124.

As a side effect of this effort, there is now less wind noise inside the passenger compartment while at highway speeds.

Now that I think about it, it's perfectly logical that after 24 years of hammering the heavy door, it's the lock mechanism that minutely moves inwards and out of alignment, and not the window.

While we had the door apart, I thought to clean up the courtesy light under the door and put a new bulb in. The light turned from hazy and yellow to bright and clear.

This and the project of the last post were done at a really great level of expertise and speed. Due to their fast pace the cost was way less than I had budgeted. At a certified merc dealership, I paid a mere 180 EUR for disassembly of the aftermarket alarm and debugging the door, after a 50 EUR coupon. Thanks for a top job, Auto-Suni.
