I've a '99 with the 2.5L 4 banger. The fan blows just fine (after replacing the heater-a/c control panel). I can turn on the a/c and it blows good and cold for at least 15 minutes when I'm sitting at idle in the driveway (I turned it off after that). However, if I start driving around, fuse #7 (misleadingly labeled "back up lp ABS", and rated for 10 amps) goes out in about 5 minutes, and the air stops blowing cold (though the fan keeps going). From what I understand, that's the circuit that runs to the a/c compressor relay to tell it to send juice to the compressor.
Where should I start the troubleshooting process? Something to note is that the a/c compressor is getting REALLY hot during operation. I'm not sure if that's normal.
Thanks for your help.
