The interior fans that blow the cool air are not working on my car ('83 300SD). I checked the fuses and they are fine. Where do I go from here? The ac is charged and I can feel the cool air it is just not being blown out with any force. thanks in advance for any suggestions.

Check if the blower is getting voltage. If it is, check the blower motor brushes. If it's not, it's not an easy answer but it's in the archives.

Yes, I second those brushes. I have gone through several motors on these cars. By design the fan is running as long as you have the ACC on, so they get alot of use over the miles. The brushes can be replaced, but I would just go for the new motor.
