How will a mechanic replace my AC high-pressure switch?
When a mechanic identifies a faulty high-pressure switch, here's the process they'll follow to replace it:
- Disconnect the negative cable from the batteryusing a wrench
- Unscrew the defective high-pressure switchwith a wrench or socket wrench and remove it
- Fit the new high-pressure switch into placeand screw it into the compressor
- Reattach the negative cable to the battery.
- Start the engineand turn on the air conditioning to test it
Keep in mind: Since you're only replacing switches, there's no requirement to evacuate the refrigerant from the AC lines. This is due to a Schrader valve being built into the mount for the switch.
What happens if I don’t replace my AC high-pressure switch?
If the high-pressure switch isn’t replaced, refrigerant pressure can build up and cause the AC compressor to burst. This can damage the entire AC unit, resulting in more costly car repairs.
What is an AC high-pressure switch?
Your car has two air conditioning pressure switches—a low-pressure switch and a high-pressure switch. Both work together to communicate refrigerant pressure with the compressor. If the pressure gets too high, the high-pressure switch signals to the compressor to shut off power.
The AC high-pressure switch resembles a small knob mounted to the compressor’s high-pressure side. This switch also detects blockages in the AC system that can lead to pressure buildup. Despite its size, it plays a crucial role in your car's AC system.
How do I know if my AC high-pressure switch is bad?
It can be challenging to distinguish problems with the high-pressure switch and the low-pressure switch, but here are common signs that you’re dealing with a bad AC pressure switch:
- AC turns on and off rapidly:The high- and low-pressure switches collaborate to send signals to the compressor. Therefore, if the high-pressure switch malfunctions, your AC might cycle on and off more frequently.
- AC doesn’t blow cold air:If the high-pressure switch is faulty, the AC won’t function at all. When you attempt to turn on the AC, you'll only experience hot air blowing in your face.
- Compressor doesn’t come on:If the high-pressure switch is broken, it fails to signal high pressure to the compressor. Consequently, the compressor won’t effectively pump refrigerant through the system to cool your car.
- Loud or strange noises:The air conditioning unit typically operates silently. Therefore, if you hear any unusual sounds like clicking or humming, it's crucial to get your AC inspected immediately. These noises could indicate that refrigerant pressure is building up.
How often should a high-pressure switch be replaced?
AC pressure switches typically last for a considerable duration, equivalent to regular usage. Most drivers find that a new switch will last the life of their vehicle. You only need to replace the high-pressure switch if it's damaged or malfunctioning.
Remember: AC switches aren't typically examined during routine maintenance visits. If you want a mechanic to inspect your AC system, make sure to request a check of the high-pressure switch as well.
Can I replace the AC high-pressure switch myself?
Replacing the switch isn’t complicated, but you do have to disconnect the battery, and you’ve got to be confident that the high-pressure switch is the culprit. If you’re having trouble pinpointing the problem with the AC, get a professional inspection since the issue could be with the blower, AC hoses, compressor, condenser, or evaporator.
