Fan fuse keeps blowing, my car keeps overheating, and the heater is not working

Hello,

According to the schematics for this vehicle, it looks like there are two separate fan fuses. I've attached diagrams (below) for your reference. Have both fuses been blowing or just one? Do the fuses blow if the fan motors are not plugged in?

It sounds like possibly the wiring harness is shorting to ground somewhere on the vehicle.

Here are a few repair guides that may help you trace the problem:

Please let us know what you find, and if there's anything else we can help with.

Thanks! Wendy W.

It's just the fuse for the fan directly in front of the engine. I will keep you updated as I try to check the electrical harness. Thank you!

Good afternoon,

Just to add to this, try disconnecting the coolant sensor with the key in the on position and see if the fans kick on. By doing that, it sends a high temperature signal, and the ECM should turn on the fans.

Do the fans come on with the A/C on?
