My 98 E 320 A.C. blower seems to be faulty. It will blow, but it does not blow very hard. Even on max, it will not blow hard. The fan control switch will change the speed of the fan, but it goes from very weak up to barely sufficient. Can anyone give any suggestions? Thank you in advance for your help.

 

Hi Monty, It sounds like you have a blocked dust filter.

The dust filter is under the passenger side of the dash, and should be changed every second service.It filters all the air which passes through your heating system, which is great, unless it is neglected.
