My '91 300TE starts the left side headlight wiper working (wiping)
whenever I turn on the headlights.
I am also getting the "bulb out" dash light... but all bulbs are

I own a 1990 300TE and have had similar electrical problems. You have
a short, most likely.
The wipers are wired such that they will activate IF your headlights
are on AND you choose to spray the windshield with fluid. The logic
is, if windshield is dirty, and lights on, activate headlight wipers.
So, I would say you have a short between the front headlight and the
control unit from which the wires eminate.
Because the "bulb out" light on the dashboard is lit, I would say you
have a headlight wire and a wiper motor wire rubbing together, or
conducting across an insertion point. Check the wires beginning at
the headlight, and move back to their source. If you can spot the
rubbing wires (maybe plastic is worn off?) you can fix. Also,
corrosion could be a problem. Does it snow where you live?
If you can't spot the problem are, you will have to hire someone to
hunt it down. Expen$ive at $50+ per hour.
Best of luck
