Classic Auto Air has been serving '65-'73 Mustang enthusiasts with new and remanufactured climate control systems and parts for more than 30 years. When Al Sedita founded the company 38 years ago to serve Rolls Royce owners in the hot Florida climate, his goal was to provide the best possible systems and parts in the marketplace. Soon, there was another demand -- classic '65-'73 Mustangs. Today, Classic Auto Air remains committed to early Mustangs, and now they've added another generation - the '87-'93 Fox-body Mustangs.

We've been instrumental in helping CAA prototype their new and remanufactured climate control systems and parts for '87-'93 Mustangs by shipping them a complete system from an '89 Mustang GT. Thanks to the efforts of CAA's vice-president and general manager Tim Cordileone, along with the company's product development staff, our 23 year-old air box was restored to like-new condition and returned for installation along with everything needed to update the out-dated R-12 system to R-134a. The key to living with R-134a has been learning how to develop new systems and components designed to operate efficiently with it. This is where CAA has done its homework with easy conversion packages you can install in your home garage and have serviced by a licensed technician.

Fox-body Mustang climate control systems operate just like their ancestors. Switch operation vectors intake manifold vacuum to three air door servos to place the air where we want it. The fan switch not only controls fan speed but also air conditioning compressor clutch operation. Fan speed is controlled via a three-element resistor, just like the classics. We get compressor clutch function in air conditioning mode as well as defrost. The three-dial electro-pneumatic climate control operates the same way as classic '67-'78 Mustangs.

R-134A CONVERSION

Many Fox-body Mustangs still have their R-12 refrigeration systems. R-12 was federally phased out in the 1990s, replaced by mandatory R-134a. This phase-out puts many of us in the unfortunate position of having to convert to an R-134a system because R-12 is no longer legally available. R-12 is also very expensive if you can fnd it. It's also complex to convert to an R-134a system because hoses, orifce tubes, system fushes, and other components have to be changed.

Classic Auto Air takes the guess work out of converting Fox-body Mustangs to R-134a with the '87-'93 Mustang R-134a Upgrade Kit. This is something you can do in your home garage over a weekend, then have the system properly evacuated and serviced by a licensed professional on Monday. CAA's simple kit includes a high-effciency parallel fow direct-ft condenser, a Sanden rotary compressor, a receiver tank, a pressure switch, brackets and hardware, R-134a specifc hoses and o-rings, and a six-rib serpentine belt. This Sanden compressor is engineered for 6,000 rpm continuous duty.
