Start with the compressor. Does it engage when you turn on the A/C?
If so, the compressor is working and the A/C system probably contains
enough refrigerant to make cold air, so the problem is inside the HVAC
unit. Replace the motor that controls the blend air door (this is a
difficult job and best left to a professional since it involves tearing
apart the HVAC unit -- about an 8 to 10 hour job!).
If the compressor does not engage when you turn on the A/C, see if it
will run by jumping the compressor clutch wire directly to the battery
(use a fused jumper wire). If the compressor works when you jump it,
and the A/C blows cold air, the system contains refrigerant and the
fault is likely a bad A/C compressor clutch relay or a bad clutch
cycling switch or pressure switch.
If the compressor does not engage when you jump it, the problem is a bad compressor clutch.
If the clutch engages but the compressor does not turn (the belt will
start to slip and squeal), the compressor is locked up and you need a
If the compressor clutch engages and turns the compressor, but the
A/C still does not blow cold air, the system is probably low on
refrigerant and needs to be recharged.
