Two fans or one?

Should both cooling fans run at the same time or does one lag the other?

both run at the same time.
low speed and high speed.
if you have issue with one of the fans or speed, most chances its a bad fan resistor.
the resistor is located on the bumper next to each one of the fans.

If one starts then the other follows after a while, try this... As soon as one fan goes on, tap on the other fan motor with a small hammer. If the fan starts the fan's brushes are toast and are barely making contact. Replace fan motor.
