vent selector
 

in my entire life i cannot remember ever wanting a/c blowing out of the dash
and floor vents simultaneously. each montana winter day though, i want to
blow heat out of the dash and floor vents simultaneously. the TJ vent
selector is set up ass backwards, and id like to disconnect the compressor
from the combined dash/floor vent setting so that i could use that setting
for heat without running the compressor. ive never been behind the panel
and i dont know what to expect. any tips or recommendations on the best way
of accomplishing this would be appreciated.

Re: vent selector
 

New to the snow are ya??

You talking dash, as in blowing on the windshield? (defrost) or blowing
out the front toward you?

Don't remember the AC kicking on with the air blowing toward me, but any
setting with the defrost on will automatically kick on the AC, and open
the vents....AC is great when the air is blowing on the floor though,
since the hot air is melting the ice/snow on the floor, which creates
crazy humidity, and fogs up all the windows....the AC dehumidifies the
air, keeping the windows clear.

if you pop off the vent grate on top, there's a screw undernieth.....and
another screw behind the ashtray...with those removed, the center dash
section should pop off, then 2 or three screws to remove the control
pod....all the wires are separate, connecting into the selector.

Do you still want the AC to kick on for the defrost settings?
You could just put a toggle switch in to break the connection for the
compressor.

i want to blow heat both on my feet and on my torso through the dash vents
simultaneously. as it is, this setting is for a/c and it turns on the
compressor.


> Don't remember the AC kicking on with the air blowing toward me

there is a dash setting without a/c, but the setting that blows out of both
the dash and the feet is a/c.


> Do you still want the AC to kick on for the defrost settings?

yeah thats fine, i just dont feel i need it for the heat settings.

thought about that but i dont want to start hacking things up. if i could
just remove the trigger that turns on the compressor at that setting id be
fine. i just wasnt sure how it worked.

I'd just throw a switch into the A/C compressor clutch ground
or break the ground at the relay. Breaking the ground side
is both safer and easier. Easy because you just extend
the line inside then ground through the switch to the body
and safer because it can't short out to the frame.

Re: vent selector
 

Don't do it. Your compressor is lubricated through circulation. If left
idle all winter, it will be more prone to internal corrosion and seals
can dry out and leak refrigerant.

Hi Sandman,
Kalifornia new cars at least since my '78 Bronco have been using
the air conditioner with the heater/defroster, as a dehumidifier. And
I've disconnecting it and even in our dry climate it reminds why we used
to carried a towel. If you like to try it just disconnect the pressure
switch unusually on the accumulator:

yeah, i dont mind using it on defrost. average speeds on the highways and
rural roads in montana are higher than in most places and since youre
driving up hill in both directions the last thing i want to do is run my
compressor if i dont need it. mileage and power are already somewhat
lacking and i dont want to hinder it farther.

You got that right. DC forgot that the sole purpose of the vent
selector is to select the -vents-! It is not for controlling any
other aspect of the environment.

I noticed that I can use that setting with the temp select on heat and
get heat from both locations. However, I suspect the a/c compressor
runs anyways.

It seems like the controls are all electrical, no mechanical linkages
like my old Escort had. As such it should be feasible to wire up
your own custom set of controls with the proper separation between the
various items being controlled. My service manual is supposed to
arrive on Monday, so maybe the schematics in it will help with that.

Many vehicles WITH an A/C button still run it in defrost mode, even when
the button is "OFF", you just don't know it. <G>

FWIW, running the compressor in the off-season is actually good for it,
and was often recommended in manuals before automatic A/C in defrost mode.

Many vehicles WITH an A/C button still run it in defrost mode, even when
the button is "OFF", you just don't know it. <G>

and was often recommended in manuals before automatic A/C in defrost mode.
