Frequently Asked Questions About Ford F600-F700 Truck Heat & AC Parts

What years and models are these HVAC parts compatible with?

Our heat and AC parts are designed for Ford F600 and F700 trucks manufactured between 1980 and 1998. Most components are interchangeable within this range, but some electrical connectors and mounting brackets changed in 1992. Always check the specific part listing for your exact year, as cab configurations (regular vs. crew cab) may require different components. If you're unsure about fitment, contact us with your VIN number for verification.

Are aftermarket blower motors as reliable as OEM parts?

The aftermarket blower motors we carry are manufactured to meet or exceed OEM specifications. They feature sealed bearings, balanced fan blades, and heavy-duty brushes rated for 50,000+ hours of operation. Many customers report these units lasting 10-15 years in commercial use. The main difference is price - aftermarket motors cost 40-60% less than Ford OEM parts while maintaining comparable quality and performance.

What's involved in replacing the heater core, and can I do it myself?

Heater core replacement typically requires 4-6 hours and involves removing the dashboard, disconnecting coolant lines, and accessing the HVAC box behind the firewall. You'll need basic hand tools, a coolant drain pan, and ideally a helper. The most challenging part is maneuvering in the tight space under the dash. We recommend having new heater hoses, clamps, and coolant ready. Most mechanically inclined owners can complete this job, but professional installation runs $400-600 if you prefer.

Why is my AC not blowing cold, and which parts typically need replacement?

Common culprits include worn compressor clutches, leaking evaporators, and failed expansion valves. Start by checking refrigerant levels and looking for oily residue indicating leaks. The compressor clutch bearing often fails around 150,000 miles, causing intermittent cooling. Evaporator cores in these trucks are prone to corrosion after 15-20 years. We offer complete AC retrofit kits that convert R-12 systems to R-134a, including all necessary fittings, o-rings, and oil.

Do you offer complete HVAC control units, and are they plug-and-play?

Yes, we stock both mechanical cable-operated and electronic climate control units. Pre-1992 models use cable controls that directly connect to blend doors and are truly plug-and-play. 1992-1998 electronic units require matching the part number exactly, as Ford used three different versions. These electronic units often need vacuum line inspection during installation, as cracked lines cause mode door failures. All our control units come with installation diagrams and mounting hardware.
