I have a 70 XR7. Ever since I got it most of the air comes out the defroster vents. It was first suggested the AC center register linkage arm could be broken. Turns out it was intact but replaced anyway since I had already ordered the part. Then it was suggested to replace the AC vacuum actuator which didn't really help. Other suggestions have been corroded rods in the heater box and the controller on AC/heat assembly. The shop working on it (stereo shop as I had am/fm/cd receiver installed and they had the dash apart for that) doesn't have a vacuum gauge but said the hoses to the AC/heat assembly weren't getting any suction from the engine and doors and rods were OK. Does anybody have any suggestions or know of anyone or shop that works on Cougars (too stiff to work much on it myself)? HELP! Thanks.
