2004 Chevrolet Blazer Question: Outside air temp sensor
Answer #1Oakman November 06, 2009, 10:29Master
The out side air temp sensor on your 2004 Chevrolet Blazer is located on the hood latch bracket behind the grill. The grill must be removed or repositioned to access the out side air temp sensor for replacement. You should be able to move the grill enough to replace the sensor by pulling the grill forward to release the retainers holding it to the radiator support.

You did what even the service manager for Chevrolet could not he had no clue as to how to reach the sensor.
It only took 3 minutes, works fine now!
