Ac stopped working 15 mins after freon recharged

This is a sign that the refrigerant charge is low. Low pressure switch will not allow the compressor to engage. Recharge the refrigerant.

Have your ac system recharged you dont have enough refrigerant to maintain pressure on the low side when the ac is running

At the very least, it sounds like your AC has lost part of the freon charge. I'd start with recharging it.

You just need a recharge.Go to an auto parts store and get a single can of R12 and the recharge line.Find the fitting on the AC line that the recharge line fits on(there's 2 but only fits 1)and hook the end on the can then on the fitting.THEN screw the puncture screw into the can lid to puncture the top of can,then turn that screw back out to release the Freon into the line and into system.To be sure you get all the Freon out of the can,stick the can in a small bucket of hot water while it's recharging your system.That's an old timers trick I use and it works.Once empty,remove the line from the fitting on the system first,remove the can from the line and save the recharge line.Ya may need it again one day.Engine must be running with AC on full when recharging the system.Stay Cool dude.

Check to see if the radiator fan is coming on & the AC fan comes on when the AC is turned on. AC Freon may be low too.

Trust you mech on this one.

There usally is a problem with the ac in general when the light does this,it can be the cooling fans are not working,check to see if they come on,when the ac is on,also make sure the freon has not leaked out.

Could be bad AC clutch relay. Just replaced mine ($11 at autozone). It is located in the relay box just behind the battery.

you should make sure there is freon in the system, what we do is recharge the system with dye, then we run if for about 15 mins, then check it with an ultraviolet light and glassesfor leaks.

freon level is low. add r134 refrigerant and your problem will be solved.
