Typically you will find this control near the receiver/dryer. DO not override it, as correct pressure is required for the system to LUBRICATE, and if pressure is not appropriate, lube will not flow correctly and system will self destruct, meaning big bills rather than realtively small repair that caused this condition.

On an ac system how do i check the high & low preasure switches and what do these switches operate and what is the purpose of them?

If your 2003 Impala had a low pressure switch it would shut off the compressor if the low side pressure got to low. This would indicate that there is not enough refrigerant in the system an therefore not enough oil flow through the compressor so the compressor is shut down.

The high pressure switch, if your impala had one, would turn on the fan once the a/c pressure on the high side reached a certain pressure.

Switches are just that, they are either on or off. A low pressure is normally on and a high pressure is normally off (this can vary greatly depending on the car).

Your impala uses a pressure sensor. The sensor reports actual pressure data to the PCM which combines info from other sensor to determine what should be turned on and when.

Hope that helps. If you have any questions let me know and I'll see if I can answer them for you.

Compressor will not engage on 2001 Impala? Where is low pressure switch located on 2001 Impala

It is located by the accumulator or dryer , a long canister shaped part, that will

have a pressure switch attached to it, and a two wire molex, if there is freon pressure

in the cannistor, the switch will close and send voltage to engage the clutch on

the compressor, if there is no voltage there the clutch will not work and you may

have a blown fuse or bad switch on your dashboard. i would check for voltage

at the pressure switch 1st, if its there, pull the molex off , jump it out and see if

the clutch engages. if you have power and you jump out the molex and the

clutch does not engage, you could have a bad clutch or bad compressor.

if it does engage, just replace the pressure switch, if you do replace it, make

sure to lube the seal with pag oil. good luck!

Compressor dont come on

Easy solution. Your out of refrigerant. When the "Freon" level drops to low, the low pressure trips a switch to kill power to the compressor. Evac, Recharge (w/Dye), try again.
