Fan Speed 67 Imperial 4dr ht

["Dick Benjamin" <DickB@xxxxxxxxx>]

The reason you didn't get an answer to this the last time you posted it is
that the answer requires more information - specifically what type of AC you
have.

While the ATC system wasn't in the literature for 1967, it was used on some
late 67's.  If you have that, the answer is that there are 5 speeds for the
blower (not 3);  the top two are only used for AC operation.  The lower 3
speeds only are used for heat.  I'm not sure about defrost, but your manual
tells you all that if you have the service manual with the ATC info in it.
If you don't have that portion of the manual, it is posted on the IML web
site, either under 67 or 68 literature, perhaps both.

If you don't have ATC (automatic temperature control), your system should
operate the way it is described in your manual.  I don't have one for 67, so
I can't quote from it to you.  If there is a blower speed switch and no
temperature dial, you have the older, simpler system.

Tell us which system you have, someone will be able to help you further.
We'll also need to know what happens when you select the higher speed (no
blower, or just the lower speed).
