I recently had my AIR pump replaced, and I replaced the AIR pump fuse in the fuse box, but it is constantly blowing and setting off my SES light!! It's driving me crazy! I have reset my computer, and replaced the fuse, and at idle, the car will not blow the fuse. But if I rev the car, or drive it at all, it blows.
Why?! Someone give me some ideas! I dont want to take it to the dealer for such a simple problem!

 

Its blowing because the pump is shorted out/no good.That fuse will also kick your fans on because the pcm is going into limp mode.Disconnect the connector on the pump itself and start your car, if the fuse doesnt blow theres your problem. Just leave it unplugged till you can get a working unit or get it deleted from your pcm.
