You have a bad actuator in the dash. There are two the one that contols the side that is not working is at fault. Of course it could be wiring or the control head but those are the unlikely options actuators fail quite oftenn.

Is the compressor engaging? when you switch it to a/c does the engine start laboring from the extra requirement? -or- is it simply the fan what will only blow on one speed? regardless of selection?
