I have a 1970 SWB 4X4 with factory AC and the air blows fast and then slow.
Any suggestions?

Check your connections at fuse panel where big red wire plugs into the front of it. This is the wire that runs your high speed.

I've had blower fan switches burn out on me every 2 years. Its like only hi-speed position works when they do.
