see this steps and think with clearly and logically NOT feared. God bless you
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
new compressor.
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.
the feon psi is at 35 psi
where would the pressure switch be ?
in the bottom of blower housing there is a circut board with two wires what is that and what does it do ?
where is the pressure switch at how do I check it ? there is a circut board located on bottom side of the blower housing with two wires what is that and what dose it do ? the freon level is at 35 psi
