Hello all my 08 hhr cool fan fuse 30A keeps blowing I know it has to be a short but I'm having a hard time finding it. Any advice???

tech2

turbo or na? how many wires to the fan motor?
inspect the cooling fan motor...does it spin freely?

Cody McCaslin

Its na turbo and there is 2 wire with connectors, and fan spins with a little lag to it.

tech2

which..na=normally aspirated or turbo...can't be both. they use different systems...charge air cooler.

Cody McCaslin

It is not a turbo. The fuse will work for maybe a hour or 2 and I have to replace the fuse.

I would recommend running a new circuit through your fusebox and abandon the old circuit.it may take some time, but a short in a particular circuit is difficult to run down. There are slots labeled as empty on your box.use new wires or you'll have the same problem
you may also have a bad fan motor drawing too many amps

fan should spin freely, no dragging. Even the slightest drag can indicate failure
