How do I check it out / repair it? Its the larger one, the one on the left when you're facing the engine not when you're driving. The right one will come on when the A/C is on or when the car gets very hot, but the left one won't activate under any conditions. Which fuses/relays/connections/sensors do I check?

 

The fuse will be in the engine bay, label "Fan" or the like.

If the fuse is OK, jump the fan to the battery. If it doesn't come on, replace it.

 

There is also a relay under the hood.

 

sorry, I forgot to close this thread out. I fixed the problem a cuple of days ag. It turned out to be the fan motor. Thanks
