I recently replaced my A/C compressor and filled it with 134a refidgerant but the compressor wouldn't cycle, so, I junped the low-pressure switch wih a paper clip and it worked fine--nice cold air.
The guage on my can of 134a read in the green zone and it's not quite into the blue area (25psi), what I'm wondering is is it just not enough pressure to trigger the switch to engage the clutch on the compressor (safety feature) or, is it the low pressure switch?
The normal pressure on this model for "charged" is anywhere from 25-45 psi so I'm thinking it just needs more refidgerant.
Lastly, 134a is expensive, if I have to change the low-pressure switch and I unscrew it from the canister will I lose all of the refidgerant?
