problem #1

Jun 292008

Trailblazer LT EXT 4.2L Inline 6

  • Automatic transmission
  • 68,620 miles

The Exterior Temperature display on the Heater/AC system shows a default 10�C despite the fact that it is currently 25�C.

This may affect the operation of the Air Conditioning system as the AC believes that it is only 10� outside instead of it being the proper temperature. This may result in the A/C not coming on because it believes that it is cold enough outside.
