i would recommend you fix the main problem before you get indepth with the blower. you have a clog in the drain pipes. if a heavy rain floods the floor boards and the water gets into the wires and components under the carpet you might as well junk your car!

update your CP

I also had water coming into the car after/during a car wash. I took the grill off between the bottom of the windshield and the engine hood on the passenger side. There is a black plastic drain there that directs water from the windshield away from the engine. Mine was plugged with pine needles so when I went through the car wash, backed up and overflowed into the passenger side of the car. My blower was in the path of the waterfall and was easy to remove to dry off.
Hope this helps.

Exactly!

To the original poster: Fix this water blockage before putting in a new blower. Else prepare to invest in another blower and a new control unit! I am surprised you are getting a blower before even fixing the water issue!

Yeah so continuing on what HotSpur was saying, there are water run offs and they get clogged. Almost always with tree debris. There are two spots to look out for one is right where the pillars meet the hood and the other is right below the wiper arm.The clog below the arm was causing the water to fill up in that area and finally over flow right past the air recirculation vent door and into the blower motor.

I took off the panel that accesses the blower motor and left it to dry out in the sun for a few days and did the same with the carpet liner thats clipped onto the floor boards. when you remove them they may still be soaked despite the top part appearing dry. Dry out the water on the metal off and especially off the AirBag Computer that sits right below the blower motor in the foot rest area. The metal plate attached to it may or may not be corroded.

I strongly recommend replacing the cabin air filter that sits right next to the motor, mine was soaked and stunk of mildew.(Upgrade and get the Carbon Air Filter) In fact more water dripped out when i removed it.I then left the system open for a couple of days to dry out. I cleaned the contacts from the motor connectors/regulator because they had corroded and caused no power to flow, Once hooked up i had the system running all day hot air. It was summer so yeah not too pleasant. The mildew went away after three days or so and for like the first 5 minutes the next week and finally all gone. I was thinking of purging the system with one of those chemicals but i was skeptical in damaging my HVAC and my health.

If you can, take some pics and write up short instructions on how you got to the drains. It will be a good DIY that we are missing.

You shall then be forever immortalized.

This problem is so simple. Clean the water collector under hood passenger side.
Consequences new AC Regulator - Blower and SRS Sensor.

Thanks,

Eddie

BTW: Check by adding water to it and check undermeath.

I just figured this one out the hard way in my 1998 C43 AMG.

Completely water soaked front and rear carpets and padding, blown SRS sensor, and blower motor that won't stop. Also a likely blown CAN module in a door.

Clean the drain, people. It's a 5 minute process.
