1998 E320...

It shows all but one bar on the fan indicator lights, but the fan is at the most, half speed. (Set in auto mode)

Is it a switch? the fan motor? Any ideas????

Let me know...any help would be great!

I had a similar problem with my 1997. It ended up being my regulator. I believe in late 1997 they changed to the newer blower regulator. All you probably need is the regulator itself. On the older 1996-1997 they changed the motor, regulator and cage to accept the 1998-up setup.

P.S. This was my original post.

Ok..took fan out. It looks great. I see the regulator. How do I know if it's the fan unit or just the regulator?

When I spin the fan with my hands it spins, but doesn't keep going. It doesn't feel like it is stuck...just tight. This normal?

Besides replacing the filters, while I have it out, is there something else I should replace/do? Is it ok to drive the car around with the fan off, (and out of the car)?

Any part numbers? (regulator)

Thanks for all your help!

I was told that I could put a regulator from the 140 in instead? How? Is this smart to do?

So many questions....

More than likely your fan is fine. If you follow the link I provided in the earlier post you will see the regulator for the W140 is mentioned by stevebfl. It is available through the Fastlane and it worked perfectly for me.

I got the 140 fan regulator like you all suggested. Stripped the wires and hooked it up. Works perfect! Very easy to do, and save about $800.00!!!!

I called Phil up from Mercedesshop.com and he had the part to me in a day! I can't thank him enough. He is a great guy.

If any of you need parts...don't mess with a dealership. Just call Phil!

Thanks again to everyone that help!
