Probably, to be sure make sure the compressor is coming on. With the engine running turn on the ac and watch the rpms, they should drop for a second if the compressor is coming on. If so you just need to recharge, the refrigerant is R-134a, which you can get from your local parts store along with the kit needed to charge it. The kit will come with detailed instructions and is a pretty easy job.

Water level perhaps. When you hit the accelerator the water volume increases. Check your water level and make sure that your thermostat is opening and closing properly. Water level I'm thinking

I have a 2003 with 140,000 with the same problem and cannot find a solution. I have to idle the engine high to get the heat to blow hot air as well.

it could be many things, maybe compressor heats up and shuts down, or cooling fans are cooling condensor or expansion valve is bad, a good tech will be able to diagnose this,

no but there are a couple of cooling fan switches that could be causing your problem both are mounted on the motor one near the thermostat housing the other will be in the block one near the thermostat usually controls the fans.

half can is low, possible cause is that fill port is clogged happens when u put sealer in sometimes, but it sounds like your system is under charged check pressure, if no reading port is clogged change port, low reading add freon,

maybe ur thermostat

WELL, IF YOU LOOK UNDER THE HOOD IN THE FUSE PANEL (BLACK RECTANGULAR BOX) YOU WILL SEE WHAT APPEARS TO BE LITTLE BLACK CUBES NEXT TO THE FUSES. THOSE ARE THE RELAYS. FIND THE ONE THAT IS FOR THE A/C. ON THE UNDERSIDE OF THE FUSE/RELAY COVER IS A DIAGRAM. P.S. MAKE SURE THAT THE A/C FAN FUSE ANMD RELAY ARE ALSO WORKING. IF THE FAN DOESN'T WORK THEN THE A/C WILL GET WARM LIKE YOU DESCRIBED. HOPE THIS HELPS YOU.PLEASE LET ME KNOW. GOOD LUCK AND THANKS FOR USING FIX-YA
