  2000 S-10 blazer LS. Very nice SUV bought for my son to go to college. This IS not a complaint but information for other owners. A/c and defrost did not work but no time for it to be in shop for first summer. Read some on here and saw "clogged heater core" with very expensive repairs. Took to local repair shop I use. They checked it out and had it back in less than 4 hours. Clogged heater core due to chemical makeup of longlife antifreeze. Flushed and two clamps replaced all for under $50. *tr

  Traveling slow on a city street. on turning a corner, the left front wheel collapsed under the car. this momentarily threw the vehicle out of control but was quickly recovered. upon investigation, we learned the upper ball joint failed, separating and causing the wheel to fold under with additional subsequent damage to the aluminum wheel. *nm
