All related to blown fuses,
1- Fuse blown in the engine compartment LH.
2- Fuse blown in the cabin forward LH below the dashboard (below your legs left hand).
3- Fuse blown in the harness (wire bundles) below the dashboard very easy to reach with your hands “just look underneath steering wheel ".
U said " The air conditioner blows, but the air is not cold.
" Yes only the fan working which might receiving power independent all from those other mentioned things.
If all fuses OK. Then look for broken wires.

the idle air control valve is responsible for engine idle.
this is a common failure on ford's. but I don't think yours is bad because it does idle high befor it dies.
you stated you had codes p0171 and p0174 these are lean codes for bank one and two, you said you found a vacuum leak and repaired it, the vacuum leak was mostly likely the cause of the lean codes, however the pcm has calibrated the fueling stategy for this lean mixture, what you need to do is erase the KAM "keep alive memory" this is done by unhooking the negative battery cable for 60 seconds, this is the only way to erase the KAM the $6000.00 machine I use wont even do it.
once the KAM is clean the computer will go into a relearn state and all operating values will be adjusted for the vehicles current condition, during this relearn session the vehicle may have some driveability issues (low or high idle, stalling, poor fuel economy) the relearn should complete within 10 minutes of idling and then 10 minutes of driving.
good luck and keep me updated

Quick tip that might help. Under the glove box is the blower fan, check the plugs that run to it make sure they have a good connection. then give the blower fan a little tap, mine was just stuck. could have been from dust or something. Or a plug might have been loose.

SOURCE: When I drive my ford
Radiator Fan Relay should be the problem..they had a recall on 01's for it..both fans need to run when the ac is on..more than likely one of the 2 is not working..change the relays
