Newbie here to the forum, and have a 97' E420. My problem is that the heater fan blows only very low no matter how high I turn the system up. It does blow hot, but very low flow. Ideas? I read on a 320 post that the voltage fan regulator may be the culprit. Is this a common problem on a 97' E420?

Thanks in advance.

 

It is a common problem. Here is a link to some god information and how to DYI:

Thanks! Looks easy enough to me.

 

You are welcome. Please reply or post your experience after you are done with the fix.

 

Will do. I ordered the part yesterday.
