Thanks newtech, that board looks a little different than the one that's there now. In the mean time, I checked voltage at EAC-1 and found there was none there. So I figured it was the blower relay and jumpered the blue blower wire to L1 to get the blower running until I can find a suitable board. I saw some Carrier control boards somewhere on the net that had some wiring harnesses that came with them. I want to make sure I have a harness that will match my original wiring.
