hi i would like some of your help with troubleshooting my AC system on my 1999 honda civic HB cx..... my car only has 90k original miles and ac is failing. i dont know what exactly is wrong but some of the symptoms are a ac clutch that locks up intermittently... i took car to sears auto to empty moisture and do a recharge. car is still doing the same thing. ac clutch locks up. when cars ac in on the air is not cool and compressor locks up. it has never been replaced but it only has 90k miles so im very confused.
