Frequently Asked Questions
Do I need to replace the accumulator when I change the compressor?
Yes—moisture and debris can shorten compressor life. Install a new accumulator and fresh O-rings, then vacuum and recharge.
My fan only works on high—what should I check?
That symptom often points to a failed blower motor resistor or a melted pigtail. Replace both for a lasting fix.
Single-zone vs. dual-zone—how do I know which actuator I need?
Check your truck’s HVAC controls. Single-zone uses 04885206AB; dual-zone uses 05073983AA. Match the part to your system.
