Selector switch issue...

The heat / AC in my Ranger only blows out through the defrost vents. I recently replaced the selector switch (to fix another issue) and everything had been working fine. The switch is working electronically as the compressor will cycle when on the defrost or AC settings. But even if I have it on "floor" it still only blows out the defrost vents. I know that the second half of the switch is vacuum driven, is there a troubleshooting procedure that anyone knows about?

Thanks,

Robert

You have a vacuum leak, defrost is the no vacuum setting. You will have to start tracing the lines back to the engine, black is the source to the switch.
