There is no low pressure cutout switch on the 1997-2001 Chevrolet Malibu. This holds true for both L4 cyl and V6 cyl models of this regardless of two door or four door. There also is not a high pressure cutout switch, but there is a pressure switch on the high side line at the top of the condensor, on the aluminum line coming from the condensor to the A/C compressor. Most parts stores will find it listed as a high pressure switch, but it actually is a transducer switch that works off the high pressure side. The compressor clutch engage and disengage functions are controlled by the on-board computer. It sends a 5 volt reference signal to the pressure transducer switch and the switch modulates the return voltage back to the on-board computer. The on-board computer reads that voltage change and determines if the high side pressure is within a certain range. If it is below that range then the on-board computer grounds the A/C clutch relay in the relay/fuse box on the driver-side under the hood, which in turn puts 12 volts to the A/C clutch engaging the compressor. Once the high side pressure reaches a certain point and the voltage return from the pressure transducer switch to the on-board computer is above a certain range, then the on-board computer removes the ground from the A/C clutch relay, which removes the 12 volts to the A/C clutch and it disengages.

This particular system of controlling the A/C clutch/compressor cycling is used on many of the vehicles GM has been building since 1994. The set up of the system varies from vehicle to vehicle, but almost all of them control the compressor from a switch used on the high side pressure line.

Where is the fuel shutoff switch located on a 97 Chevy Malibu?

Fuel cut off/ Inertia switches are a Ford/ Mazda feature only. The only type of fuel shut off switch on a 97 Malibu is the ignition lock and key. If you're trying to find this switch because the car won't start and it has no fuel pressure then its not too unlikely that the fuel pump may be bad. They die all the time on Malibu, Alero and Grand Am.

How can I adjust the well pressure switch to ensure optimal performance of my water system?

To adjust the well pressure switch for optimal performance of your water system, follow these steps: Turn off the power to the well pump. Locate the pressure switch, usually near the pressure tank. Use a screwdriver to adjust the cut-in and cut-out pressure settings on the switch. Increase the cut-in pressure if the water pressure is too low, and decrease it if the pressure is too high. Adjust the cut-out pressure to a level that provides consistent water pressure. Turn the power back on and monitor the system for any changes in water pressure. Remember to consult the manufacturer's instructions for specific guidance on adjusting the pressure switch.
