1st: Those aren't 194 bulbs behind the heater controls. They're special made Honda/Acura, bulbs that include the base, that they couldn't even order for me at Autozone/NAPA/Checker/local place. There's 4 of them back there, and the dealer wanted like $18 and a week to ship them in. I said screw that and went to a local Honda/Acura place that had them in stock for $12.

2nd: to get the unit out of the console you have to disconnect the heater slider wire. Get down under the passenger side dasboard and look up towards the center console. There are some white plastic pieces there with some stiff metal wires. The heater control is a mechanical linkage, so slide the heater button back and forth until you figure out which wire you have to remove. Slide the heater control all the way to heat. The wire should just be looped around a plastic post, and it should come off pretty easily. Don't pull the center console too far out or you will have to rethread the wire, which is a *****. I know this sounds a little vague, but you should be able to figure it out.
