Overheating issue :(

I've read many of the threads about how to test different parts of the cooling system but I'm stumped!!
I've removed the ECU lead from engine temp sensor, which should get the rad fan working, but nothing happens. I've increased the 15 amp blade fuse in the box to 20 amps and this makes no difference.
The problem is that the engine is overheating in slow traffic and when under load when not travelling quickly (up steep hills - I live in Wales!)
What's the next thing to test? The fan itself? If so then how can I test it? Maybe the lead going to the fan? Again, how can I test it?

Any help would be great as I love the car and would hate to pop it

It's possible the fan is dead, does it keep blowing fuses?

never tested the radiator fan before but copy and paste from another thread

"un plug the sensor that you can see on the metal part of the water system....bottom right hand side of the engine....ones on the bottom thats for the temp dial....the other one sticking out horizontaly is the fan...when un plugged the fan should run continuously!!

its where the water comes out of the block into the hose and to the top of the radiator... "

if this dont work why not get another from the scrappy i picked up a almost brand new rad complete with fan and all the pipe work for 10

I'm afraid I can't offer any more advice than others have said on the main issue.

However I can advise you never to replace blown fuses with higher values. the fuses are all at different values for a reason, increasing that limit could cause serious electrical damage by allowing more current through than is intended, its just not a sensible thing to do.

Put it this way. Would you still use a hair dryer that had just blown a fuse but been hardwired to bypass it? I didnt think so!
