The sunroof may not work correctly due to failed components as a result of age and wear. Repairing a sunroof can be labor intensive and very costly.

1990 Mercedes-Benz 300TE Problems
The bushings for the shifter lever wear out to the point where they break and fall out. This causes excessive movement (loose feel) in the shifter lever and a clanging-type noise when changing gears.
The part that attaches the distributor rotor to the camshaft can break; the starter will still crank, but the engine will not start.
One or more blend door vacuum actuators may fail resulting in the incorrect output temperature from the HVAC system. Failed actuators will require replacement to restore proper HVAC operation.
Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.

Occurs mostly in warm weather and occassionally while running. Thermostat stays pretty much at midrange. Replaced idle control valve and ran good for a while then problem recurred after a month.
All the other cabin lights works.
I have replaced the transmission with a new one. Replaced the O2 sensor, the cam sensor, the BDU, and had a full service on the car. All to no avail...The car is fine to drive around town, smooth ...
My car is actually a 1988, but I wasn't given that choice
1990 Mercedes-Benz 300TE Reviews
love the car but always seem to need something. Best family car EVER
I have purchased a 1990 300TE. Bodywork fab, general condition is awesome throughout. Some slight problems with the transmission, but nothing that a transmission oil change and check on vacuum pipes won't cure. All in all fantastic! My car has completed 217,000 miles so far. good for another 200,000 with good care.
It's a Benz. Like no other car.
The only problem i had is the
premature suspension failure (at 168K miles)
Replacement parts are rather costly, and so
is the expert service. It is NOT a car to
take to Pep Boys.
