I have a 2009 R350. A couple days ago, the blower motor remained on after the car was turned off. I tried to disconnect the battery from the front fuse box, but it remained on. it was midnight, so I have up. It was still on in the morning, and the car started, but didn't start the next time. It was fine for a couple days, but the motor is stuck on again today. Searching on line it looks like it could be the battery going so a relay stayed open, a bad relay, or water on the motor or relay. I am changing out the battery tonight since it is 5 years old anyway. Can someone tell me which box has the relay in it, and also how to determine if there is water near the blower motor?


Thanks alot for the help.
