Heater/AC Vent problems
When I have my heater or A/C on, no matter what setting I have it on, I
can only get air coming from the floor vents, and/or defroster vents.
When I put the 'slider' on the dash vent setting, i only get air coming
from the floor vent and the side window defroster vents, but nothing
from the actual dash vents.
I've briefly looked for a hose or something that has slipped off, but
it's pretty tight in there and thought I would ask here before I rip my
dash apart.

You didn't mention which vehicle... we'll go on the
assumption that you have a vacuum-operated
vent system.
A question... does the venting air ever change
when you move the slider around? My system
defaulted to what you describe when the vacuum
line to the vacuum reservoir got melted... this
was right by the battery (I used a torch to melt
solder on some battery connections, dangerous,
I know). Same air venting, no matter what
position I had the control (****, on mine).
My cruise control wouldn't work, either...
dead giveaway on a vacuum problem.
My vacuum reservoir is underneath
the passenger side front bumper on my '00 XJ.
All I had to do was splice the tubing with a
piece of 1/4" ID rubber hose and all fix.
I went ahead and bought a vacuum pump
bleeder-tester... but I like tools, you might
not want to spend $30 on one. I didn't
need it to fix my problem... if all your
lines are OK, then you're going to have
to start testing reservoir vacuum (the pump
has a gauge!). The pump can be used to
test vacuum motors, too... this is the diaphragm
that moves the vent doors, changing your
air path.
I have the FSM for my Cherokee, as well as
both Haynes and Chilton for earlier years.
I suggest you get at least one of these
resources.

Re: Heater/AC Vent problems
I want to thank you for posting this information. I used this as a
guide and it led me right to the problem, which was also in the vacuum
tube below the battery.
Thanks again
