2001 Isuzu Rodeo LS after adding Freon A.C runs warm and cold

I added freon to my car and thinking it would do it some good it now puts out warm and cold air when I have the a.c running goes cold for a minute or two then warm then back to cold and so on. Anyone else have this problem and how can it be fixed. Thanx

Are you using the street way using the single can method? When your adding the freon does the fan by the radiator come on and is the ac compressor engageing? I am not sure if the car ur referring to has a sight glass but if your system is empty you might be completely out of freon and have a major leak. adding the freon will cause the compressor to come on only for a short while adding more will keep it engauged adding too much will shut it down. make sure the fan is coming on by the radiator.

It sounds like by adding refrigerant to the system it may be over pressurizing. When this happens it will cycle on and off.

You will need to hook up a set of manifold gauges and monitor the high and low pressures to see what is happening.

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.

2001 Honda Passport/Isuzu Rodeo a/c not getting cold, fan in grill not turning, there is plenty of freon and inside controls/fan working fine. Is there a fuse for the other fan?


Yes there is a fuse for the other fan, generally inside the engine bay as apposed to inside the vehicle. I would think it is more likely to be the clutch on your compressor unit that is not engaging when you press the AC button. In this case the fuse on the AC button is responsible and this is also found inside the engine bay. Check either of these fuses and you should get the AC working. If not then there may be insufficient pressure in your AC system or your compressor unit needs changing out.

Compressor cycling everything seems fine but no cold air. whats could the problem possibly be besides a bad compressor


If one of the ac lines coming from the condenser is cold, could be low on freon or a problem with a blend door under the dash.
If none of the lines are cold, could be a faulty compressor, blockage in the lines, or low on freon.

Ac compressor on 99 isuzu rodeo turns on and off . already filled with freon. air is cold but not consistently


Does it have the correct amount of freon, it can still blow cold with the wrong amout of freon, this will damage the compressor,you may also have a bad cycling switch or bad high preasure switch and even a bad connection to ac system,this first thing is to make sure the correct amount was installed,

A/c


If Freon was "added", the system may have moisture in it and that causes blockage of the expansion valveand makes the soamolies hijack oil tankers. Just kidding. Figured this would be all foreign to you anyway, no offence.
Ok, Adding freon is not really a good fix. The system should be evacuated with a vacuum pump to remove any moisture in the system which will freeze and block the expansion valve, Hence, no cooling.Having the signs of this problem already should have called for evacuation. Adding freon from a kit increases the possibility of introducing more moisture into the system. You will need to have it properly service at this point. The drier will also let go of any moistue it has trapped when evacuated for 30 minutes @ 29 in. of vacuum - good luck

I had same problem on 2000 Lesabre blowing cold on passenger and warm on driver. I fixed it by adding more freon even though it had 28 pounds of preasure. Now it works great!
