Question2002 Oldsmobile Silhouette V-6-3.4L Vin E 76000 miles. My
AC was not blowing cold air and not much force. I had the
condenser replaced and the cabin air filters replaced. Now
I have a great amount of air blowing thru the vents. I used
a thermometer to measure the temp. I have cold air down to
40deg. F. This is cold air.
The blower will blow air thru vents and can be changed to
the different settings. All the settings work. Air will
also blow from the rear vents when using the front panel or
the rear panel. The problem is while the air is blowing the
temp will fluctuate, or not come on at all. Then for no
reason the temp will drop. I can feel this with my hand and
watch it on the thermometer. I also notice that the
thermometer will form condensation on it. This is a signal
that the air is cycling off. The ac will cool for about a
min. and then cycle off for around 30 sec. this will
continue until I turn it off. Then when I stop for a break
and restart the van the ac will not cool, the air blows but
will not cool. Then it will start to cool and cycle.
While I was playing with all the controls, I moved the
climate control slides up and down. I then noticed that I
was getting cold air on the driver’s side and HOT air on
the passenger side at the same time. The climate control
sliders were both in the same position, all the way at the
bottom, (cold air position).
Today on my way home I stopped the van and let it sit for
about 2 minutes. Then started up again, I turned on the ac
but no cold air. Also non tempered air was blowing from the
rear vents. I got in the back and controlled the ac from
the rear controls and still non tempered air. But the front
was cooling.
I have taken my van back to the service center a couple of
times. He said after he replaced the cabin air filters that
he did not have a good feeling about the unit. But go ahead
and drive it and see what happens. I have taken 4 trips of
150 miles at a time, and another of 100 miles. I have had
the van back to the service center and he cannot seem to
find the problem. Of course it was not very warm the days
that I was able to leave the van with him. I now have this
extra information and would like any feedback that you may
offer. Now it is very warm (80-95 deg F), and the problem
is worse. When first started the ac will not kick on for
about two to five minutes. Then will cool for a minute or
two and go off. This cycle repeats and the thermometer
never registers below 55 deg.
AnswerHi Mike
Gave me a lot of information lets take one at a time. First the levers: Need to know if your system is automatic temp. control or manual. If manual your doors for the heater work on a cable check and make cure they are connected properly. When you say cond. (by the radiator) or the Evaporator (inside the dash). Need to know if compressor is running while vehicle is not cooling. Let me Know
