Assuming your 1987 300E does not have a cabin air filter... The blower resistor/regulator is located beneath the blower motor. Follow the procedure for getting to the blower motor, then remove the motor by diconnecting the red and blue wires. Then remove the motor cradle. There are 2 hex-head screws securing the blower regulator. Remove them, then wiggle the regulator out carfeuuly, toward the drivers side (left) of the car. There is a pin in the bottom of the regulator that fits in a hole underneath it, so you have to work that pin out of the hole below the regulator. The regularor you need is available from several vendors. The Replacement-brand SKU is REPM191902. The original Mercedes part number is 2015400845. IF your vehicle has a cabin air filter, the procedure is similar, but the Replacement SKU for the part is REPM191901. BE VERY sure you order the correct part. The wrong part would be electrically equivalent but has a very different shape and will not fit.
