Hi everyone, i know there been a couple of threads out there about this same issue. all with many different solution/resolutions.

to me, this is wat happened...


-Meter fuse (15A) blows out every time u put a new one in it.
- my first step was putting a 20A fuse to see if it still blows and it did. so in my opinion this would mean tat there is a short somewhere in this circuit.
-i followed the diagram, which i saw in another forum, and saw tat the wire tat comes from the fuse runs to the relay #1.
-so i disconnected relay #1 and tried to see if the fuse would blow again, and it did.
-so then i was like "screw it", i disconnected all 4 Relays and i also disconnected the TNS, RETRA, and AIR COND relay. and guess wat, it still blew the 15A fuse.
-tat would mean tat there is a short in between the 15A fuse and relay #1 correct?

Can anyone help me out?

The FD's fan control system was revised a few times during production. Also, the METER fuse has its hand in a few other things too. Have you looked at Section W: Power Distribution in the wiring diagrams? Since I don't know what year your FD is, I'm gonna default to the earliest possible ones (1993 model)

From the 10/91 Japanese diagrams, the Meter Fuse feeds the Cooling Fans (as you described), Combination Meter & Warning Lights, Rear Wiper & Washer, Turn & Hazard lights, Horn/Stop Light/High Mount Stop Light/Back-up Lights, EC-AT Control Unit, Shift Lock system, Key Interlock System, TWS Unit #2 (AKA Body CPU 2), Rear Defroster and quite a bit more. The US spec ones are bound to be similar, it's just been awhile since I looked in the North American documentation.

It would be wise to arm yourself with the Wiring Diagrams and Manuals from here:
