I really don't think my problem is the blower motor.
The sound is real close to the center dash vents. The sound doesn't come from anywhere else.
When the air comes out of the two side dash vents, there is not ticking noise.
When the air comes out of the floor or the vents near the windshield, there is not ticking noise.
If it was the blower motor, the sound should be there regardless of where the air was coming from.
Does anyone know how I can examine the area behind the front center dash vents. The ticking noise is definitely localized here.
Are there separate fans that blow air through these vents only?
