Usually, when the fan works only on high speed the issue is with the blower motor resistor. It will be located under the dash close to the blower motor itself. It will have a multi-wire plug and feeds signal to the blower motor. An updated resistor maybe available in which case a slightly larger hole will have to be cut for the new resistor. This is not a difficult proceedure, only a couple of screws are holding the resistor in place and most resistors are resonably priced. I recommend you buy the resistor at the dealer, this is a case where you get what you pay for.
Good luck, hope this helps.

Above the Relay Panel is the Auxiliary Relay Panel. Has thirteen positions in it.
6 across the top, 7 across the bottom.
Across the bottom the Glow Plug Relay is the fourth one over from the left. It is Number 10.

SOURCE: Heater Blower Motor not working.
I don`t know what year your car is but my 91 Escort had 4 little connections under the glove box where the passengers feet would be right in front of the blower moter (i.e. some one sitting in the passenger seat could hit these 4 relay type things if they kicked their leg) and my had been dammaged and that stopped my blower motor from working until I straightened them out and reconnected them all.

Here are the locations of the fuses and relays. F-31 through f-42 probably are the one you want to look at. These are probably all tied together from looking at your codes. Your mass air flow sensor is also giving you an alarm. If your not finding any blown fuses or bad relays it might very well be the PCM (Power train control module) itself that is going bad. A dealer will have to check that out for you.
