IS AN EARLIER ACCURATE DESCRIPTION OF SAME PROBLEM. WEB WISDOM SUGGESTS A/C CONDENSATE REPEATEDLY COLLECTS ON THE CRADLE CAUSING (HIDDEN) CORROSION. THAT SEEMS PLAUSIBLE TO ME, SINCE MY CAR IS RUST FREE, INCLUDING THE UNDERCARRIAGE, EXCEPT FOR THE HEAVILY CORRODED CRADLE. ACCORDING TO WIKIPEDIA GM PRODUCTS THAT SHARE THE SAME GMX130 PLATFORM USING THIS CRADLE ARE: 1999?2004 OLDSMOBILE ALERO 1999?2005 PONTIAC GRAND AM 1997?1999 OLDSMOBILE CUTLASS 1997?2003 CHEVROLET MALIBU 2004?2005...
