My AC doesnt blow cold anymore, possible its just fuse?

lots for reasons, (huge in fact) cold is 10x more complex than hot.
scan the PCM for errors first. DTC errors
check fuses.
Is the AC compressor clutch engaged?
the 2 lines on this compressor one gets super cold as it passed in to the firewall.
hand on, it even see moisture form on it like cold beer bottle does.
if yes this shows up then the problem is in the dash.
dampers doors dead (blend)
recircu mode.
cold set,
the service manual covers all this, DIY folks need that book
some AC (mine does) has HVAC self test in the book.
with flash codes, (damper blind dead?)
RTM read the manual is always best, check for blown fuses.1st.

There is a relay in the fuse box under the hood near the battery, it's marked MG/CL it controls the compressor clutch.

There is a fuse and relay for the compressor. Most times when it doesn't come on and is full of freon, it is the high pressure switch that is bad.

either a fuse or a bad heater core, hidden somewhere behind your dash.

Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also.
If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?

COULD BE MULTIPLE PROBLEMS...LOW FREON = NOT COLD..BAD COMPRESSOR =NOT COLD=LEAK IN 1 OR MORE HOSES OR EVAPORATER OR CONDENSER =LOW FREON =NOT COLD.SO WHAT IM GETTING AT IS LOTS OF POSSIBLITIES,IF IT HAS THE PROPER AMOUNT OF FREON IN IT YOU SHOULD BE ABLE TO SEE IF THE CLUTCH IS SPINNING ON THE COMPRESSOR.CHECK ALL THAT I WOULD SAY TO PUT SOME FREON IN IT BUT IF YOU PUT TOO MUCH YOU COULD DAMAGE THE SEALS AND =NOT COLD FOR GOOD.THANKS AND GOOD LUCK.

your air con needs re gasing

Hi i'm ryan, is it blowing cold air, or just won't come on at all? If its blowing cold air try checking the antifreeze level, low levels will cause it to blow cold air. If it is just not comming on at all, try checking the fuse for the heater.

broken cable? if possible trace the cables back to the box move then bolth and see if one doesnt, if so you could alwase manually move it for a temp fix
