Hey Guys, I'm new to the forum and it seems like people are more knowledgeable here than other forums...

I followed this method "Radiator fan doesnt work at all"
https://honda-tech.com/forums/showthread.php?t=2889629

and it led me to #5 (No)

5. Disconnect the jumper wire, and turn the ignition switch ON (II). Check for voltage between the #3 terminal of the radiator fan relay 4-pin socket and a body ground.
Is there battery voltage?
Yes - Go to step 9
No - Check for an open in the wire between the under-hood fuse/relay box and the under-dash fuse/relay box.

I have a 97 Integra hence my username..

On my DVOM it shows -0 voltage so meaning theres no voltage going on..

on my schematics it shows a black/yellow wire that goes to the underdash fuse box to fuse #13 (cooling/heater fan relay fuse)

Fuse is good, but i get no power when i hit it with a test light..

Anybody know where the black/yellow wire specifically is by the fuse box (underdash)?

(tired of the bypass that was done by the previous owner and i want my fan running right... running way too rich and not hitting normal temperature + dumping a bunch of fuel)

Thanks.

Fuses can look good from top but the blade can be broke. Replace with a brand new one.

Apply 12volts from battery directly to fan motor connector to see if it isn't broken or burned out

Already checked fuses and relay under the hood and there fine, also i already replaced the fuse under the dash as well and nothing... as well as testing the motor fan that was already done... thanks though..

my main concern is finding the black/yellow wire under the dash by the fuse box that is for that fuse.. it might have an open or a loose connection..

Yah it's always fun doin that......get a good flashlight lol

Blah i just wish i knew which black/yellow wire is the one for fuse #13, unplugged like 4 plugs from the fuse box underdash and tested for continuity with 4 different black/yellow wires for terminal #3 in the cooling fan relay socket fusebox underhood and none of them had continuity.... hate this..

how much?
you could always bypass it..

dc97

been on this for about a couple weeks now just slowing moving forward and i got far , usually busy most of the time...

it already is bypassed... just wanna do this right..

So when you put a jumper wire in the fan switch connector the fan doesn't run at all?

dc97

Nope, only when i jump terminal #1 and #2 from the cooling fan fuse relay box(underhood) it turns on..

dc97

Bump

What do you think it is bro?
fan is good, i can jump it from the relay box, but i cant jump it from the fan switch plug... ground is good, been using my dvom and test light to check things out..

Fuse #13 7.5 doesnt light up when i hit it with a test light, ign on II and off.

Will it turn on if you jump the ect connector
