- Reconnect the negative battery cable
- Start the engineand test the air conditioning
What happens if I drive with a bad AC pressure switch?
Both the high pressure and low pressure switches must operate together for the AC to function. If one of them malfunctions, your AC won’t cool the air in your car, and persisting in using it could harm the compressor. Consequently, you might face more costly car repairs!
What is an AC pressure switch?
A pressure switch, also known as a pressure sensor, is integral to your car's AC system. It comprises low-pressure and high-pressure switches that collaborate to relay refrigerant levels to the compressor. These switches safeguard the compressor by signaling if pressure levels become excessively high or low.
Both of the switches resemble small knobs and are mounted directly on the compressor. The high pressure switch notifies the compressor of high refrigerant pressure and blockages in the system. The low pressure switch cuts off power to the compressor if refrigerant levels are insufficient to operate correctly.
Both switches play a crucial role in ensuring the smooth operation of the air conditioning system.
How do I know if my AC pressure switch is bad?
If either switch is malfunctioning, they'll typically exhibit the same signs. Here's what to look for:
- AC cycles on and off rapidly:If one of the pressure switches isn’t functioning properly, the AC will cycle on and off more frequently.
- AC doesn’t blow cold air:If one of the switches fails to relay accurate pressure readings to the compressor, the system cannot generate cold air.
- AC compressor doesn’t turn on:If the high pressure switch is broken, it won’t signal high pressure to the compressor, resulting in the compressor inadequately pumping refrigerant through the system to cool your car. If the low pressure switch is damaged, it could lead to compressor failure.
- Loud or strange noises:Your AC should operate silently if it’s functioning correctly. If you notice any unusual sounds such as clicking or humming, it's imperative to have your AC inspected promptly. These noises could indicate a buildup of refrigerant pressure.
How often should a pressure switch be replaced?
Pressure switches typically endure the lifespan of the vehicle unless they malfunction or sustain damage. Generally, a pressure switch can last for around 50,000 cycles, equivalent to turning the system on and running it for about 20 minutes each time. Replacement of the switch is only necessary if it ceases to function properly.
Can I replace a pressure switch myself?
If you're confident in working on your car's electronics and comfortable disconnecting the battery, replacing a pressure switch should be relatively straightforward. However, diagnosing the exact problem with an AC unit can be more challenging due to its intricate closed-loop system.
AC problems can be caused by any number of components like a malfunctioning compressor, evaporator, condenser, or blower motor, for instance. If you're not completely certain that a pressure switch is faulty (and you can identify which one needs to be replaced), it's advisable to seek a professional diagnosis through Mymechanic in Malaysia.
FAQs
The high pressure and low pressure switches are both situated on the compressor. Refer to your car’s diagnostic guide to identify the high pressure side, indicated by the color red, where you can locate the high pressure switch. Similarly, the low pressure side, marked by the color blue, contains the low pressure switch.
