Air conditioning problem, need troubleshooting help with "73" Mustang A/C
In my 1973 the air conditioning only comes out the defroster vents, any idea on how it make it come out of the main vents? This Florida heat is killing me without a/c.

You prob have a VAC line that's leaking... Check ur VAC lines from the firewall for burning, leaks, damage, etc. Sorry I don't know the specifics for your car... Someone else might know. My SD did it once and the VAC line was messed up by the battery from corrosion
