Glad I could help. I'm not much of a poster on here, more of a lurker looking for answers / ideas for the problems I come across from time to time...and I love a good build thread! I hope the other poster got some help too...

Sorry I don't have the book with me, or i'd let you know. Your owner's manual has all that listed, I think like page 127 or something....If I get a chance tonight I'll look at mine.

This is also assuming you do this in conjunction with the resistor and plug, meaning you've taken them apart and confirmed they are not burnt!
4ST AIR helped me out a lot with various threads on here (My resistor was burned, and I wouldn't have known there was a resistor in the circuit, much less that it was a bad one), but the info above is incorrect.

I didn't have power on the second fan fuse, but the fuse and wiring looked fine. From the schematic in the Chilton's manual, the second fuse is only powered when the low-speed fan relay is active - so you would not see power at that fuse unless that relay was bypassed (jumpered across), or the engine was hot enough that the PCM was trying to turn on the fan.

Just to clarify for anyone else trying to troubleshoot the fans not coming on.

(Info is for a 2002 Focus SE, but I think should be good for most 2000-2004 Foci, not sure about an SVT).

This is going to sound weird but try turning on the AC( click the button on). My father in-law had an issue with his zetec anf a resistor and his fan will only come on when the AC is activated. Quick fix for him, but he'll have to eventually get it fixed.

Yeah, I told a guy how to unplug his AC clutch and bypass the LP switch so he could get his fan running with no charge and a bad resistor.

Okay - first off, the OP fixed his problem - I was just commenting for others trying to run through the same issue.

Second - the low speed fans (both fans) operate through the resistor - but the OP already replaced that.

The high speed fans operate when the A/C is on (and also based on the WOT setting according to the Haynes manual).

Rather than disconnecting the AC clutch, it is probably better and easier to bypass the relay (I think it's the high-speed one - not sure) like this. The fans run (high speed?) all the time when you do this, so you probably don't reach peak operating temperature, but the advantage is that you can still use your A/C.

Hope This Helps!!!

Either method has one major drawback: you fry your fan motors. Those fans don't generally run at all unless the vehicle is sitting still because you don't need fans when you're moving. When you continuously run the fans, then you wear out the fan motors sooner.

My point being- no matter what you do, it is a temporary fix. The longer you leave it like that, the more likely you are to have to spend several hundred dollars for new fans.
