Quick facts
- Part: Dorman 904-9921 A/C refrigerant pressure sensor
- Fits: 1990-1996 International 9300 and other vehicles
- Condition: New
A failing A/C refrigerant pressure sensor can show up as an A/C that will not come on, cooling that comes and goes, or a warning light. Before you replace the sensor, rule out low refrigerant, a damaged connector or wiring, and a faulty compressor clutch circuit, since any of these can also keep the A/C from running. If the sensor is the cause, this one replaces it.
Fits
The vehicles it fits include the 1990-1996 International 9300 and the 1990-1996 International 9400. If yours is another International model or year, search the "Vehicles it fits" section with your own year and engine.
