AIR PROBLEMS

I have a 96 chevy corsica and my air will not work! All at once the fan
and the air stoped working could this be a bad relay? all my controls
work fine for the heater and the vent. The fan only turns on if the car
gets hot enough and will not turn on when i turn on the air and the air
feels just like the vent when it is turned on.

thanks

ok last night i thought maybe the switch was bad for the compressor so
i by passed it and the compressor turns on ok but it will not cool that
way even with the air turned on. I now think it could be the sensor
since the fan is still not turing on.

Sounds like a pressure sensor, or the system could be low on
refrigerant.

Time to get out the old test light and ac gauges like low and high
set.

And say no to them death kits.
Wal Mart DEATH KITS

You cannot properly and safely recharge an air condition system with
them.

The one side stop and go gauge does not tell you what your system is
doing or is over charged or undercharged.
A overcharged or malfunction air condition system can reach over 500
lbs of pressure.
Enough to blow up that can or system and freeze you at first and the
burn you or blind you and if any propane /butane in there blow and
light you up.

The stop leak crap and who knows what kind of oil in the kits there
will stop your system for sure.
Just like pouring super glue in it.
And some kits even contain freon with a butane mixer.
Good for a big blast.

If you are going to do it do it right and safe.
Here is what you need to start with.

In the older days you could just throw in a can and go.
But over the years just adding freon is getting harder to do.
Newer systems have to have the correct amount of freon down to the
ounces.
Most will need pumped down and vacuumed down and the right and amount
of oil and a set amount freon charge installed to get the air to cool
right and the system to last.
If an air condition is low there is usually a leak that needs fixed and
also a lose of lubricating oil from system.
Also air and moisture enters a low system
If you are going to try to do it get the proper type air condition
gauge set with the low and high side gauges.
Hook up the gauges and get a reading with compressor running at idle
and at 2000 rpm on the high and low side.
Post back pressure reading and we can help you.

That is part of my problem i brought it to firestone shop and they
looked at it and told me that it was a elertical problem and that was
all they could tell me they did say it was full of freon so i piad 40$
for nothing from them.

Well you caught me.
Copy and past from MS Word
Saves a lot of typing.
I may have to reword it a little to keep it interesting.
