how do I kill power to a constantly-running blower motor? on 1998 Mercedes-Benz E320

Air blows even with ignition off & key removed.. even after pulling all associated fuses listed in manual. Presently having to disconnect battery to prevent drain.

Replace blower motor regulator via Amazon you will get good oem part for about $118 solves problem. 10 screws to get out 5 minutes replace regulator another 15 minutes put unit in and cover under dash and bam most likely you will get nice cold air coming out. Amazon delivered in less then 12 hours to my door.Make sure you buy German part.always around $100
