2007 Kia Spectra5 94,537 mi,
The AC completely stopped blowing. It didn't have the noise like when the AC is on, but the AC was on. Then it clicked on and I heard the noise
AC quit blowing cold air. Mechanics found AC belt missing + Abnormal wear on Compressor Clutch. Recommended new AC Compressor (~$1000) & AC Belt (~$35). Couldn't afford new Compressor at time, so opted for new AC Belt for temporary fix but told that it would most likely wear away and break unless new Compressor installed.
