I know this group is not for Kia but was the closest I could find. Any help would be appreciated! We have a 2002 Kia Spectra. For some time now we have had issues with the A/C. Here is the situation.... Once the car has sit over night (only happens when it's hotter, during the summer) you go out, start the car. Wait a minute or two and start the A/C. You will hear the compressor kick on, then the belts slip and you hear a loud noise. The noise is not the typical squeal you would hear from belts but more like a grinding noise. It only last a second or so but can be very loud and will often shake the car. This has already bent one pulley which was replaced by the dealer but this did not resolve the problem. I have had the car into the dealer 4 times for this issue but they can never fix it. They have replaced the pulley mentioned before, other times they simply tightened the belts which also did not resolve the problem. It has been frustrating because we know there is something wrong but can't seem to get anything fixed. It only seems to occur during the summer months when it's hot, during the winter when you use the defrost the compressor still kicks on but acts normally. Please help! Thanks, Tony
