Helpful Notes

Year coverage: Many HVAC parts list 1994–2002; your 12-valve years are included—always check each product’s fitment notes.
Replace in pairs: When swapping a compressor, replace the accumulator/drier and metering device (orifice tube), then evacuate and recharge to spec.
Fan speeds dead? A failed resistor or overheated connector is common—use the resistor with pigtail when needed.
Blend vs heater door: Temperature complaints often trace to the blend actuator; mode issues (defrost/floor) point to the heater door.
Heater lines/tubes: Aging hard lines and molded hoses cause leaks—Fleece/CPP line kits and Cummins heater tubes are direct-fit fixes.

Frequently Asked Questions

What should I replace when installing a new A/C compressor?

Best practice is a compressor + accumulator/drier + orifice tube, plus proper oil, vacuum/evacuation, and recharge. See GPD 6511617 and GPD 1411266.
