Does anybody know if it uses R-12 or R-134a? I inherited the car from my father and am finding the air conditioner shuts off from time to time... just blows tepid air instead of cold. It doesn't matter whether it's set on AC or Max AC. At least it's intermittent. I figure it just needs a charge.
I am not interested in a major rebuild at this time as it still works and I've already spent a chunk of change getting the brake system squared away along with a new radiator. Gotta let my wallet cool down a bit first....
