Yes it is that's why he has to have the a/c on so the car won't overheat.

I missed the isnt. Sounds like your other fan is bad(slow or not moving).


Check the relay, wiring, switch

If the fan works, check the coolant too. If there is more antifrezze then water, it can overheat when it's real hot out.
