Blower regulator location

If anyone needs to know about 92-97 MB climate control I Know now. I took the total system apart under the hood and found they (regulator and resistor) are in the filter compartment. Easy to remove and replace. Lot of screws though. However, before replacing anything check and make sure the motor bushings are not corroded and sealed to motor. That's all that was wrong with mine. The motor would not turn, was frozen. Light turn released it. corrosion was on aluminum components in this area also. System works fine now. By the way, the battery is in the trunk on the passenger side, below a panel.
