I The diag ran well and the evap fan faulted as expected. I had installed a new board and fan before running the diag. I pulled the control board and followed the purple wire and blue from the board and backwards towards the fan. I could easily see that the insulation around the resistor was discolored from getting too hot. I had to do some driving but I was able to buy a couple of new resistors for $1.57. Tech Tip: The electronics store owner helped by telling me that a replacement resistor could be a little different than the original. The original resistor is a 10 ohm, 1/4w, 5% spec. The store had the same resistor with a 1/2w spec instead of the original 1/4w. He told me I can always go up that amount of wattage but never go lower than the original wattage. I installed the new resistor and the function of the evap fan has been restored. My Weller soldering gun had a broken tip and none to be had close by so I crimped that resistor on that wire between the board and the fan. An unusual .75 cent resistor failed. The fan failed. The evaporator coils froze up. I think the board was trying to power that fan after it was frozen and the component failed. I replaced the board with a known good used and guaranteed one. I will keep the original board as backup. I hope this post and thread can help somebody find an unusual item failure.
Made me wish for a Radio Shack store to be around again,..
