aircon working OK?
Ok, first of my hopefully few stupid questions regarding my new (to
me) '97 JC 4.0l...
When I turn the aircon on the electric fan runs for between 9-15
seconds, followed by 5 seconds off, depending on the interior cabin
fan speed I select and engine RPM. At idle, fan speed 2 = 9 seconds
of external fan, top fan speed = 15+ seconds of external fan, followed
by 5 seconds off. Does this sound right?
I then measured the internal temp of the airflow. Outside ambient is
15 deg, inside cabin 17 deg. airflow in cool mode (no aircon) is 14
degrees. With aircon it's 7-9 degrees. Sound OK?
Got the towbar fitted today, so went for a tow with the 1800kg trailer
and it pulled like a steamship. Stooped like a steamship, too!
(trailer brakes did more braking!), but pulled fine, even on inclines.
Haven't tried at any speed yet, so not sure about any sway issues yet.

Re: aircon working OK?
Hi Dan,
It is normal for the air conditioner compressor's clutch to engage
for about those lengths of time and then cycle, if that's what your are
talking about, rather than the electric blower motor that should run at
the speed you set it to. Fifty degrees Fahrenheit sounds great to me.

Thanks Bill,
I'm used to cars like Saab etc where the compressor and fan run for
longer periods with longer rests between. Thanks again.
I see that there is an additional cooler in front of the radiator - am
I right in thinking this is the auto transmission cooler and that the
aircon condenser is built into the radiator?

I think that if you follow the plumbing lines to the front radiator, you
will find that it is part of the air conditioner system. The trans cooler is
very small if there is one. If there isn't one, then you will find the
plumbing to it going into what passes for the bottom tank on the radiator.
Some radiators have the tanks on the sides, I am not sure how the Cherokee
is configured, and the bottom tank is the one opposite the tank with the
filler cap on it.
Like Bill said, the fan itself inside the passenger compartment should come
on and stay on where ever you have set the speed control. The A/C clutch
will cycle off and on, but for the most part this is completely transparent
from the driver's seat.
