First, you're sure the problem is the fan switch and not the fuse or change-over switch. These cars use the same fan switch to operate separate AC and heater blowers, with a vacuum operated change-over switch mounted above the gas pedal to switch the electrical circuit from one blower to the other, depending on the position of your AC temp control knob. If the heater blower works but not the AC blower, it's probably not the fan switch.

The fan switch knob and shaft are held in place with an internal spring clip. Pull the fan knob straight out. You may need to gently twist the knob as you pull in order to get the clip to release, but do NOT try to unscrew it or you will break the switch. Once the knob/shaft is out of the way, you can unscrew the chrome nut to release the lower part of the vent panel. Also pull off the 4 knobs for the sliding controls. Before pulling off the vent panel assembly, remove the radio grill and speaker from the dash so you can reach in the hole and unclip the rubber air duct. Unless someone's been in there before and lost them, this rubber duct should be attached with several plastic button clips. Then you'll need to go through the vent with a long screwdriver and unscrew the captive philips nut on the control lever to disconnect the fresh air control rod. Once the vent panel is out, you should see two small screws or bolts holding the control/switch panel in place. Also unfasten the two fiber-optic cables that illuminate the sliding controls before pulling out the panel. Hope this helps.

Happy Motoring, Mark
