Thanks again Arthur.

On top of the termostat housing there are 2 sensors. A small one with a single cable and a bigger one with 4 cables. Disconecting the big one turn the high fans on. I'm attaching a picture of the sensor and another of the "manual" AC controls.

I'll do some reading on the fan mods and get the new clutch in a couple of weeks (taking the kids to Orlando for vacation this weekend). I'll post back when I get the fan installed and tested. Oh, and I'll start to read about removing the fan clutch. It looks dificult. I haven't found the way to block the pulley to get the central screw loose.

Thanks. Juan.
