1) The passenger side wiper arm is not moving, but the driver's side does. Is this a common issue? (I hope not expensive to fix.)
Haven't heard of that one on a Benz, but I've had it happen on a Volvo. If you're lucky maybe it's just stripped the wiper arm. On most cars I've had, the wiper shaft is splined, tapered, and made of steel, while the wiper arm's center is very soft aluminum. The steel shaft actually cuts splines into the arm when the nut is tightened. If the arm is a little bit loose and the wiper gets frozen to the windshield, the arm will strip. The cure is to remove the arm, clean any metal shreds out of the splines on the shaft, and reinstall. Every time you do this the arm will sit a little lower on the taper. If it gets to the point where it won't fit snugly anymore, shim with aluminum foil. (That said, I don't know if Benzes use this particular arrangement.)
If you're unlucky the linkage has come apart under the cowl. It still might not be too hard to fix.
2) The left side turn signals worked fine, when the right side turn signal was activated, it just buzzed from under the dash near the glove box?
Buzzing relays often are a symptom of a bad ground somewhere. I'd clean the ground connections and bulb sockets at the fixtures. If you've got one where the parking lamp or four-way flasher doesn't work, start there.
Some people have also reported successfully curing turn signal problems by cycling the four-way flasher switch repeatedly for a while, like a couple hundred times. The turn signals are routed through there and dirty contacts sometimes cause problems, since that switch is rarely used.
Also, we noticed that the fog lights were clear, this doesn't seem typical. Comments?
Could be they're clear fogs, or maybe someone replaced them with driving lights. Do they throw a wide, flat beam like a fog lamp, or a longer, more penetrating one like a driving light?
