15A fuse to radiator fan relays 1 & 2 keeps blowing

[bayzoo]

Hi,

Aside from my suspension issues, after putting the clutch and subframe back into the car, when I go to turn the key to the on position the 15A fuse feeding the radiator fan relays blows - it’s done this twice now. My electronics knowledge on cars is limited so I’ve got a guy coming out on Friday, but had anyone else here experienced a similar issue?

My guess is it’s an earthing issue but I was careful to reinstall everything. I’m worried I may have pinched or damaged a wire somewhere, or coolant may have damaged wires when it spilt out upon my changing the thermostat.

If there are some basic test I can do without trying the ecu I don’t mind giving it a go. Google suggest numerous options but don’t know where to start!

I have found a doc that has wiring diagrams and slowly trying to figure it out. The fuse is called INJ - here is the wiring diagrams doc:

These are the error codes I’m getting:

Can we assume that this wasn't a problem before the clutch work?

If so, a fuse blowing means an overload, which likely means a short to ground somewhere. Given that a lot of work has been done, and it is a new problem, I'd check the previous work done looking for a damaged wire/connector.

Thanks yes that’s correct it was fine before I did the work.

It’s such a small engine bay I’m dreading having to un do a lot of the work but it looks as though I’ve no option.

Would it make sense to start with the radiator fan wires or could it literally be anywhere? I have a cheap inspection camera I can try and use in hard to reach areas.

Sounds like a wire trapped between two things - bellhousing and block - subframe and "frame" - I vote have a feel around and see if the wires going to the fan are stuck somewhere.

Great I’ll try this first.

Is it possible there is another circuit on this fuse that’s causing the car not to start? I find it unusual a fan not working would stop the car from starting unless I have 2 issues.
