Six months ago, the blower stopped working. I replaced the inline fuse under the dash, and everything worked fine..for a while. When I push the heater button, the A/C compressor kicks in. When I push the defroster button, the A/C kicks in. When I push the A/C button, the A/C kicks in. Problem is the blower never kicks in. It'll cool a little if I drive really fast. The electric fans start up. How do I trouble shoot the climate control? Where is that f'ing fan? Is it behind the driver's or passengers kick panel? Is there any other relay that I should check? How much fun is that fan to change?

The fuse is just behind the front firewall, just forward of the fuse panel in its own little container.

If that is not the problem, I found cracked solder joints on the pushbutton switch assembly in the dash that made the fan intermittent.
