Just did injectors, raptor 150 lift pump and head gasket in my 1995 12v now all the sudden a/c goes on and just blows air. Used to be ice cold now its just outside temp. Heat works great..but I live in FL . Don't really know anything about the a/c on these trucks so any suggestions are welcomed!

 

Check wiring and connections to the A/C compressor. Check fuse and relays.
