1991 Mercedes-Benz 300SEL Problems
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.
Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.
The instrument cluster, along with the turn signal and wiper combination switch, can fail.
Motor mounts commonly fail, causing engine vibrations to be transferred to the body. Failed motor mounts should be replaced in order to prevent damage to the transmission mount.
