Hi DSMers,

I have a 1Ga Talon TSI AWD. I have been having an issue with my rad fan not turning on. I went to Isaque's place last night and we found that the 30amp fuse attached to the battery was blown. We swapped it out with a different 30amp fuse, took it for a spin, and it blew again.

I am not an electrician, but I would guess there is something wrong with the rad fan motor for it to keep shorting out the fuse? Seized? Would the solution be to replace the rad fan?

Also, it should be noted that with my IC setup, the AC fan was removed and that spot is vacant. Is it possible to directly swap the non-functional rad fan with the working AC fan?

thanks,

Danny

How easily does the rad fan turn by hand? Sounds more like a wire shorting.

The fan blade does not move easily at all. Very stiff.

Ah, well then you may be right. You should be able to easily spin the rad fan by hand.

Not sure about swapping in the AC fan; I would recommend replacing the main rad fan with another one.

Thank Jeremy. I appreciate the help.

You can use the AC fan in place of the rad fan to troubleshoot, and pinpoint the short. I doubt it will push enough CFM to actually be used as the sole rad fan though, it'll probably stay on constantly.

Yeah I had that happen before on a car I bought. All mine needed was a radiator fan that spun freely

There you go Danny... Seems like we just need that new fan and you'll be able to drive that beast without worrying about being stuck in traffic! LOL...

So Bryan, you suspect that there could be a different problem, i.e. a short somewhere? Implying that just because I buy a new fan does not mean my problem would necessarily be solved?

In which case, yes, would be a good idea to test things out with the AC fan sitting at home first to be sure there are no shorts.

Thanks,

There may or may not be a short. There is most definitely a bad rad fan.

I would start by replacing what you know to be bad. If there are further unknown problems, they'll be easier to find without known problems getting in the way.

Basically a process of elimination, if you suspect the fan being the issue (which seems likely) replace it with the AC fan temporarily, run the car to it's nominal temp and see if the fan comes on without popping any fuses. If that works than you have proven the problem to the rad fan, replace it and away you go!
