I have a few wires i need to wire that i was told were grounds by the fan relay there the 3 black ones with silver dashes i believe and there are 2 wires on the same harness both white but one with red line and one with green line just wondering what they are.

 

Anyone?

 

Does anyone know ive been doing alot of research but cant find anything.

 

I'm not sure what they are for, but are you having any issues with the car?

 

Fan wont kick in. These are the end plugs at the end of the wire bunch that has those 5 wires hanging out.

 

What year, model car is this?

U.S. or Canada?

A/C or no A/C?

What color wires are at each separate connectors?

 

The black wires are various ground wires that probably go to the Ground block G201. Looks like the cooling fan relay ground wire is already connected to Ground G201.

The White wires with colored stripes running through them are usually power wires.

I was waiting for you to answer my previous post to try to figure out all the connectors with the disconnected ground wires.

 

Late 89 dx no ac I believe the white plugs are for lights. But grey plug one on both sides blue/red wire white/green wire then there is a green plug green wire yellow stripe with black wire.

 

The green plug with the Yel/Grn and Blk wires probably is the connector for the coolant temperature switch. The blk wire for the coolant temperature switch goes to ground G101.

That may be the issue with the cooling fan.

I'll see if I can find the grey plugs.

 

Connectors with Blu/Red and Wht/Grn wires look to be for the respective left and right horns.

 

Ok i have my fan wired and its grounded out and it never kicked on so i got a new relay how long tell the fan kicks in at idle?

 

Coolent temp switch is plugged in.

 

You said green plug with Green/Yel and Blk wire; I incorrectly looked up Yel/Grn and Blk. I'll see if I can find it.

Edit: It doesn't indicate what color connector it is; but, Grn/Yel wire and Blk wire connector may be for the turn signal light. Both left and right turn signal lights have Grn/Yel and Blk wires.

 

With the ignition in RUN, when the coolant temperature rises above 194 degrees F, the coolant temperature switch should close providing ground to the coil of the relay and the fan should run.

Disconnect the coolant temperature switch and jumper the harness connector with a wire or small paper clip, with the ignition in RUN, does the fan spin?

 

By jumper the harness you mean? Connect the two wires basically?

 

Yes. This is a temporary test to try to narrow down the cooling fan issue.

There are other tests I can guide you through too.

 

Ok so i did that test and the fan turned on but when i connected the 2 wires.

 

Since the fan ran when you jumped the harness connector wires, it means the fan motor, relay and wiring in between are good.

Does the coolant temperature gauge rise above normal (e.g., overheat) when idling, etc.?

If the fan does not run when the coolant temperature rises above 194 degrees F at the switch, it may be due to a faulty switch.

 

No the gauge does not over heat but the switch worked when engine was pulled. Could I do a simple fix and wire those two wires together and have the fan alway run?

 

There may be something wrong with the switch now. But, you may want to check for low coolant levels or air in the cooling system which sometimes can affect the fan switch on some Hondas.

Yes, you can hook up a switch to manually turn on the fan, which a few people do. Your fan motor may not last as long with it constantly running though.

 

Changed temp switch still nothing.

 

 

 

💋 In response to hooking up a switch to turn the coolant fan on.Well ,why? Because if your trouble shooting(been there done that on 95 Delsol 1.6 vtec d-series/sohc..)
I 1st wanted to test the fan motor.So I unpluged the wareharness from the fan put aligator clips from fan motor wires straight to poss. And neg. On my car battery.THE FAN WAS GOOD.. HOOKED FAN BACK UP!So then I tested fan sensor on THE THERMOSTAT HOUSING Unplugged harness from sensor of housing by passed the end that goes to sensor with a paper clip..Got in the my car Turned on the a/c cont. Button and my Fan dial turned key to aux (one turn)on ignition.And vuol'a.Both fans turned on.. which in turn gentleman definitely leads to the fact that the sensor was bad and it allowed my fans to turn on without hooking up any different switches until I could get the part ordered. The right part LOL because they kept trying to sell me the temperature sensor located under my distributor as opposed to the one on the housing of my thermostat. This also keeps from having to sit there and wait forever for your car to come to temperature to even check to see if the fan kicks on at all. Because like I said I troubleshot fan first because well one it was easier. And2 I had just gotten that fan not even a year before so I was going to be pretty ticked if I had to take that whole fan out again to replace it in such a short amount of time. Hope this helps guys. If in fact it is on the lines of what your questions were pertaining to to begin with. If not maybe take note in case you have to use it another day.
