I don't buy in to the diagnosis of the blower motor control being the root cause because the climate control, as Doug explains, has gone to full heat, no temp control either.
It's possible that one of the fuses is providing no power to the climate control. It may have other power sources which are providing power to run through the test progrm and allow the LED's to switch, but missing another power source to actually control the temp and fan.
With the key ON or car running, check some of the fuses for power using a meter or test light. Check the fuse chart for ones which refer to the climate control system.
I had a 140 acting similar to this (at least in regards to the blower motor, unsure about temp control) which ended up having a bad ignition switch of all things-not even providing power to one of the fuses which the climate control uses.
