Mercedes-Benz 300SL Problems
As vehicles age, various problems may develop with the hard and soft tops. If problems are encountered, it would be recommended to have a technician familiar with these tops perform the diagnoses.
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.
A coolant leak may develop form the Radiator due to degradation of its plastic components. Replacement of the failed radiator will be necessary.
On high usage vehicles, the ignition lock may become difficult to turn due to wear of the ignition lock and tumblers. Replacement of the ignition lock cylinder will generally be required to correct this concern.
Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.

air conditioner not cold blowing cool
my 1991 300 sl was experiencing symptoms of running fine when cold, and breaking up and stalling when engine got warm. changed crank sensor, no fix, still getting stuck on many occasions. car wold only start when it cooled off. thought it had to do with some kind of temperature sensor..changed fuel filter, and the problem went away. driven hundreds of miles trouble free now..car often sits for few weeks at a time, especially in winter. love this car..two tone black, silver body color..looks awesome, also has adaptive damping option, which I'm told is rare for a six cylinder..a keeper!!
My 1991 SL mercedes is a beautiful car. When it sits for a long period, once driven, it cuts off. The car will start after sitting a couple of hours. Restart car and drives fine.
Nice car but does have a number of issues after 20+ years. There is a wealth of information and help on the MB forums. The bad "green" wires came in 1994 for a few years. And, EZL's do NOT explode. (Where does this stuff come from?)
the best car I ever had
