|---|---|---|---|---|
| REIN | ACS0243P | 🇺🇸 US 🇨🇦 CA | View on Amazon |
This table covers the pressure switches on the A/C circuit. Typical signs include a function that works intermittently, or a click without the accessory coming on. Inspect the connector behind the switch; heat-damaged terminals will kill the new part too.
