2002 Mercedes-Benz ML500 Question: Rear a/c blower

the rear blower on my ml will run sometimes when the ignition switch is off, also it will run for very short periods an cycle on and off?? -
Answer 1
sounds like a sticking relay, find the relay/fuse center & tap the blower motor relay when it is running with the key off. if it turns off replace your relay. there could be many other problems but this is simple & easy to test. -
