Out come to Airflow Question asked another way
1. The airflow from the AC in my wrangler comes out the bottom vent,
the
top vent , and the defroster all at the same time no matter how I set
the controls. Can someone give me a general idea as to how the airflow
is controlled mechanically so I can begin to figure out the problem.I
know how to get at the control panel which appears to be vacuum unit I
just don't know if its a vacuum problem, control problem or possibly a
baffle issue.
2.Ok,
I checked under the hood as Mike suggested to make sure all vacuum
lines in place and secure. Everything appeared to be correct and in
place. Also determined that you could figure out if vacuum was
working by turning on blower & AC with out the engine running. I
identified 3 vacuum control units closest to driver under dash in a
line running up to top of dash. First one appears to switch between
hot and cold. The top two seem to work together with the center one
controlling the bi-level and floor flow. That one appears to have
almost no movement when you switch it back and forth so it is suspect
along with vacuum control unit at this point. I have also determined
that on all settings the largest volume of air is coming out the
defrost area .
The center unit has two vacuum lines running to it , the others only
have one. That's as far as got , need some else to do some switching
back and forth while I check lines. That's tonight's project, will
report back tomorrow
3. So far I've come up empty handed on all vacuum issues but the
blower motor now only works with AC, nothing at all when I try to run
heat. The Vacuum switch is a rotary type with a 3 wires plugged into
the side of it so I'm starting to suspect that's the problem. One of
the wires, 2 green and one black, appears to have overheated and
melted the plastic at some point. I cleaned and replaced the three way
plug with individual wires but that didn't help. I hate to give up and
take it to a dealer( Haven't found one in Mpls, MN worth a damn) but
unless someone can point me in another direction I'm out of Ideas.
Thanks

Re: Out come to Airflow Question asked another way
I would be checking the dash grounds for the electrical issue. I read
somewhere, but can't find it again that the ground on the dash falls off
f you bump it which craps out the heater fan switch. The fix is to
drill and tap it for a new bolt.
Do you have a vacuum gauge? They are really cheap.
I would be putting a vacuum gauge on the intake manifold, say at the CCV
nipple and then start pinching closed vacuum lines, starting with the
one going through the firewall.
If the vacuum gauge moves even slightly when you pinch closed hoses, you
have a leak in that line.

Don't have a vacuum gage now but that's a good reason to get one. Is
there more than one ground strap for the dash ?
