Randy, the only way to clean it without removing it is to take out the blower so you can snake a shopvac hose in there. You can also reach in there with your arm, and some brushes to brush the dirt/gunk off the fins. I did this a few times, using the shopvac to then pull out the loosened dirt. Be carefull not to bend/damage the fins by jamming the shopvac hose in there. I also blew some air from the aircompressor in the center vent to backflush the evaporator. After all this, when I put it all back together and turned on the hvac system, I was greeted with a nice cloud of dust out the center vent into the car.

Excellent tutorial. I need to change my blower motor and the resistor pack. This was just what the doctor ordered. These tutorials are what makes Rennslist.com such an invaluable tool. I did have one question though. What MY was this done on? Once again great job. Jason

Jason, I did this on my 87-S4, and on Brian's 88-S4. Let us know if you have any questions.

Yes, it should be the same. The only difference might be the resistor pack...I don't think the early version is available now. You can use a newer version, with a slight change in the wiring plug. Easy to do, I found the details on Bill Ball's thread about changing his resistor.
