I'm new to the Mercedes family and am the proud owner of a 95 E 320. Is the replacement of the heater fan with squirel cage blowers beyond the scope of the home mechanic? My 95 e320's fan is squealing (same pitch @ different fan speeds) and I would like to replace it myself. Do I need to pull the wiper assembly to do so?

Hi Brian,

I too am new to the Mercedes family and my 95 C280 has a high piched chirp all the time. When I first got the car about a month ago, the fan started "ticking", then I had it cleaned out and it has been squealing on start up and always has a little chirp going. Need to fix it soon, before friends test my new Benz out.

I will be awaiting forum members input to see how difficult and expensive this will be.

I have used 2 types of lubricant on my c36 to try to quiet the fan. A creeping type of wax based lubricant was most successful. I have simply oiled the bushings on my old 190e and gained about 2 years of extra use before the squeak returned worse and I broke down and replaced the fan. The link I postd is for the 202 model. Remove the fan and work the lubricant over a couple of hours into both end bushings. Clean up any leakage/overspreay. Don't use WD40 as it will not last. It's easy mechanically to do, but twisting your body around to work under the dash is never easy. T15 is the Torx driver size you will need.

Benzfan- Thanks for the info, but could you give me a name or specifics on the "wax based lubricant" that you used on the blower motor ?

Moly grease was dissolved in laquer thinner and then squirted on the top and lower bearings. I also replaced the motor brushes with generic starter brushes which I sanded down to exact size.

Total cost = $2.00 or so for the brushes at a local starter alternator repair shop. My labor = ?? took several hours since I was in new territory. You could search for my post (DanielW) when I did my older 87 300E (124 bodied) car. The hardest part was removing the wiper assembly and trim around windshield.

Luck to you,
DanielW
