Hi,
Yes, you would have to open the system to replace or clean that valve,
but in my experience they are rarely
the culprit. Don't open up the system until all other possibilities are
exhausted. Any bubbles are bad...suggest you have the hi and lo pressure
on the system checked,
an easy job with the proper gauges and manifold.
This might be just a problem with the baffles ( moving panels/doors ) in
this fancy system, if the "door"
is closed on the evaporator ( under the dash ) you won't get any air
flow past the evaporator and hence
no cold air. Is the fan running ? Probably the same fan for both heating
and cooling, just the baffle
controls the air flow. You can call me if you like, I do a lot of A/C
work on older cars, and my Dad had
a number of these from the late 50's up to the early 80's, I worked on
most of them at one time or another.
919-550-5117 leave a message if I'm not there I'll call back
Regards,
John

Subject: IML: 65 A/C Question....
Hello Group:
I have an A/C question that I couldn't find the answer to
while looking through the archives, repair sections, or in my own
National Service Data manual.
My 65's A/C system goes through all the proper motions, but
I am not getting cool air inside the car. I suspect that the expansion
valve may be the culprit. The TEV is cold, the line leading into the
plenum is frosty, and there are just a few bubbles in the site glass. I
checked out the heater core valve (?) and it closes and opens as it
should when the temp lever is moved, the compressor is running,
starting, and sounding as it should.....
I have read about cleaning a screen in the Exp. Valve, but I
would need more specifics on how to do that.. would I need to have the
system evacuated?
One last small question: There is a knob by the driver's left
knee that says floor air. When the car is not running I can turn that
knob but nothing really happens, when I start the car and turn on the ac
the knob turns itself to the left towards the floorboard, and while the
car is running I cannot budge it left or right..... what exactly does
floor air do, and is this something contributing to no cool air?
Thanks everyone,
Eric
