I agree. The ModeSwitch is the big knob in the middle of the panel, below the radio. It consists of an electrical switch supplying power to the blowermotor and the A/C compressor at the appropriate settings and a bit that switches vacuum to the various flapper doors under the dash. > Are there any other things I should check for? I'm quite positive it's the modeswitch; the hissing you hear is probably a vacuum leak. You wouldn't happen to have been messing around behind the center console? If so, you probably knocked one of the hoses loose, else the diaphram in the switch might be worn.

If you still have the original Circuitbreakers this could be tripping, causing the fan to alternate between speeds 2 and 4 as they are on separate feeds. If on 4 with the original CB it could trip, opening up the feed to speeds 3 and 4, so the fan gets its feed from speed 2 untill the CB cools down and restores power to the realays for speeds 3 and 4.
