charged my ac three weeks ago worked great yesterday it started blowing super hot air opened the hood and clutch was staying on however i thought maybe low pressure charged and the indicator went straight too warning >> released all the pressure tried again nope no cold air and all keeps building pressure any ideas where to start looking here

 

Were you checking pressure on the low side or the high side?

If your low pressure is going high, it's most likely because of lack of airflow through the condenser.

If the high side is going too high, it is probably due to a restriction in the system, usually at the fixed orifice. Recover the system and remove the valve and inspect. Metal debris indicates a failed compressor. Grit or sand-like material is usually due to dessicant failure in the accumulator.

Just a thought here, but the blend door actuator could have failed it mixes the hot and cold air to adjust the temp. On my Taurus (it has auto climate control) it has gone out 2 times both times in the summer and both times the door was stuck so that only hot air would blow out.
