I need to know where low pressure switch for A/C is or if there is not one can I evacuate A/C and get a enough refrigerant in with vacuum only to get compressor on?

Hi,

As far as the pressure sensor, there is only one and it is referred to as an A/C pressure sensor.

Can you explain what is happening? Also, does the vehicle have automatic or manual climate control?

As far as vacuuming the system, you will need special tooling. Take a look through this link:

Also, take a look through this link. It explains what to check for an inoperative or weak A/C system.

Let me know if that helps.

Take care,

Joe
