I have a 2000 civic lx 4 door with automatic transmission!!!
When I come to a stop my temp gauge rises and my fan doesnt kick on.
I've gone through the main troubleshooting and everything is working fine.
I replaced the thermostat and the fan switch. I tested the fan motor and its fine, and all of the relays are working like they should. I took my multimeter and tested the fan switch plug and it gets voltage, BUT then I checked the plug for the fan motor and its getting no power. No blown fuses, no relays bad that im aware of, I searched up and down and couldnt find any cut wires. I really cant figure out why the fan isnt getting power. any ideas??

 

i would 1st check your antifreeze make sure you have enough or do a flush and put fresh coolant in

if your worried about the fan you can always hook it up to a different fuse or use a toggle switch

but thats me b/c i dont have alot of wiring experience

 

If you unplug the fan switch connector and jump/short its 2 terminals with a wire, does the fan run when the key is turned to ON(II)? If so, start by bleeding the cooling system:

(This procedure may take 20-30 minutes)

1) Park the car on an inclined driveway with the front end higher than the rear.

2) Push the dash heater lever/**** to MAX heat.

3) Follow the directions in the diagram below

 

I've already done a flush. twice.

 

Flush and bleed are two different animals.

 

I bled it both times as well

 

Does the lower radiator hose get hot when the engine is overheating? Or does it remain cool?

 

I will check and let you know

 

its hot
