I have a 2002 Ford Explorer. Lately I've noticed a 'clicking' sound coming from the cargo area.
It's a sound like what the hazards would make when they're on ... a 'clicking' noise. It seems to have something to do with the
fan. It's louder when I have the rear A/C fan blowing high, and quiets down when I turn the fan down. Anyone know what i
could be?
