Angry NO >> AC/FAN/AIR/HEAT (3 Blinking Knobs)

I've got the original model w/ 79K miles, after taking a pit stop at the petrol station, My AC/FAN/AIR/HEAT didn't work. I starting the engine, all 3 cabin climate control knobs blink in unison.

I consulted the user's manual, checked the fuse box for the #13 fuse labeled as the AC/AIR fuse. It is a #10 red fuse, but was not expired and in good condition.

Is there anything else I need to research or is there a catastrophic failure of the HVAC and need to head to the Repair $hop?

I would pop off dash panel and check the plug in clips first.

I remember several people having problems with the fan resistor when the H3 came out. It gets hot and doesn't work properly - as I remeber they weren't very expensive, just a pain to get to next to the blower.
