I have an 89 300se. I have had the car about a year and the air/heat has always blown, but not blown very hard. Last fall, I had the brushes replaced and at that time the armature looked fine. The mechanic admitted that the fan did not blow really as hard as it should have. We never dug into it to resolve. I have since purchased my second benz(420sel) and had to replace the blower motor because it was completely worn out. The fan on the 420 blows about 3-4 times as hard as my 300. Could the armature be worse than expected or could the blower motor itself just be worn out? Any help would be appreciated. Thanks. Scott
