I just tried something different. The last time I jumped it with the key on and off and no fan but this time I actually started the car with it jumped and the fan came on after I turned the engine off.

So now up to date on this issue is that I have the fans working but the check engine light is still on (see my post: code 6) and my S light is still flashing (see my post: code 10) and I have yet to know why the fuse blew.

Both of these codes point to the ECT as the fault.

 

Since that made the fans run, I guess that really IS a fan switch. Maybe with all the rest of stuff you're doing, you disturbed the wiring to the ECT sensor?

So now where is the ECT sensor located on a '90?? Someone out there has to have a '90...

 

The ECT (Jim as you now know also from the other thread) is not located on the water jacket and it's the problem.

I have noticed the fan motor makes noises and slows down at times so it's on it's last leg and about to go out. I assume this is what put the load and blew the fuse.

I'll replace the fan motor asap and the issue this thread dealt with is now sloved so thank you everyone for the help.

 

The car got a new radiator fan motor today. Thanks again for everyones help.
