Air conditioning not working on dodge intrepid. added freon. still blowing out HOT AIR. what do i do now?

May just need freon added to A/C unit. About $100.00 to have that done cuz most systems now days have to be drawn down then dri system and then add freon Hope that helps you.

Was the compressor running when you hooked up the gauge ?

probably the evaporator core under the dash leaking

Usually a sign of low freon charge or flow problems.

YOU CAN USE SMALL JUMPER WIRE OR PAPER CLIP CLOSE CIRCUIT ON LOW PRESSURE SENSOR OR HOTWIRE THE COMPRESSOR.

vacuum down to 30 inches for an hour recharge let me know what kind of readings you have

You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....

Your cars use R134. Older cars have to be converted to R134

The "O" rings could be bad thus allowing all the new freon to leak out again. This happened to us.

sounds like not enough freon or orfas valve is clogged. but most likely it is low on freon
