Why is the Freon not working on my Chevy Tahoe?
Those readings indicate low and no compressor activation. Here’s what they found, when they measured the pressure they said it was 11 PSI on the low side and 100 PSI on the high side, with the engine idling at 2,000 RPM. So basically low on freon.
Where are the low and high AC pressure switches located?
The low-pressure side switch is found before the AC compressor, while the high-pressure switch comes after the compressor. Most AC pressure switches are found within the engine compartment, but some manufacturers put them elsewhere. A look in your service manual will show you the appropriate location for your model.

What happens when your air conditioner pressure switch goes bad?
When you turn on the air conditioning, you expect to feel cold air pour out. However, when the AC pressure switch goes bad, warm air might be all you get. However, this problem is also caused by low refrigerant levels, which should be checked regularly. If the compressor is clicking off and on, you are going to notice some strange sounds.
Why is my AC compressor not pulling Freon?
THANKS! So with the system reading 25 PSI on the low side and 25 PSI on the high side with the vehicle idling, I threw in the towel and took in to a shop, an independent shop not the stealership. Those readings indicate low and no compressor activation.
What does the low pressure switch on a Chevy do?
The low-pressure switch is designed to shut the compressor down if the pressure becomes to low or the evaporator freezes. The oil for the compressor is suspended in the Freon, and if a leak in the system occurs, the oil, being heavier than the Freon, will be the first thing to leak out.
Why is my AC not working in my GMC?
Please try again later. If you have a car made by GM such as Chevrolet, Cadillac, Buick, GMC, and Pontiac and your AC does not blow cold air and the A/C Compressor is not engaging it does not mean for sure that you have bad ac compressor or bad ac clutch coil, or low on freon, it also could be a bad ac pressure switch.

Why is the AC clutch not engaged when the Freon is low?
No, the AC clutch will not engage when the Freon is empty or low. The low-pressure switch will prevent the AC clutch from being engaged, and the compressor will not spin. This prevents the compressor from engaging. The major reason the Freon is low would be due to leakage.
