Question about 2000 Ford Explorer

A/c blows hot even after i have put in freon.

Last week while driving home I notice that my a/c was feeling to hot for normal operation. So I stoped by a local parts storeand picked up a can r-134 put it in my system. It cooled for the ride home but the next morning it blew hot again.

Yes you have a leak. Take it to a shop for the test. It can be done in a few minutes not costing you an arm an leg. 10 chances to 1 it is an O ring like already suggested. They should not even sell this stuff to the public! The prob of a leak needs to be corrected before adding anything. Thank God it wasn't your fuel tank! LOL Frankster016

Most likely the additional charge you added leaked out overnight, these systems are very prone to leaks in 2 area's, the AC condensor core and the line O ring seals.

    YOU WILL NEED A LEAK DETECTOR, THEY ARE VERY EXPENSIVE, YOU MIGHT GET LUCKY AND SEE AC OIL AROUND THE LEAK, IT WILL BE GREEN.

97 Plymouth Breeze won't blow cold air due to freon leak.


Your AC system is a closed system, so the fact you have to put more Freon in, means there is definitely a leak. I would check it out with a mechanic.

Air conditioner blowing hot air on 2002 monte carlo and it has freon in it


car air conditioner blowing hot air is cause by either a leak or a clogged condenser, since it has a freon in it then it might be a case of clogged condenser but this is just a contributing factor, it is possible that the leak is small that you wont even notice that the freon is not enough for the a/c to blow cold air.

During a three hour drive back home, our AC stopped blowing cold air. If you stick your hand in front of the vent, you can feel cold air, but it doesn't blow. If you turn the fan up all the way, you can...


Have your a/c pressure tested, the clicking could be the a/c compr coming on and off due to low freon, it will do that so it don't damage your compr when there is none or low freon.

I would suggest to check the evaporator, normally found underneath the glove compartment. Check out the coils and the fan. While you are at it you can do some cleaning and see if it helps.

1996 LX - Condenser Fan Blows Fuse


Make sure your are using the right amp fuse, if so you will need have the fan relay checked by a mechanic. The porblem would be in the wiring of the car since there is not much to a air conditioning system in a civic. As for the air not being cold you may have a leak in the plumbing of the air system that needs to be fixed because freon is very expinsive.
