Yessss I also have a 07 accord and one of my fans aren’t working either!! I didn’t know I could check the fuses first! Thanks so much now I’m about to check your other video out!!

Best video out there by far. Question please when jumping the fan from the battery the fans will spin but not spinning fast at all.

Hi, I have 2006 Accord and none of the fans is working. Relays and fuses are fine, so are the fans themselves (connected them to battery). I've changed the temperature sensor (the one on the engine). Any suggestion what could be the issue? Neither of the fans is working even with AC on, but AC works fine. The engine is not overheating either. Please help😂

I replaced my thermostat, heat wasn’t working- now it does… but now my fans aren’t working when heat is on, but when a/c is on they work? Any answers

[mrwise]

I've inspected all my fuses, relays, and the fan, and everything is functioning properly. What else would you recommend I try?

Stupid question, is the radiator fan supposed to be on at all times? I changed a fuse for my blower fan since it was out and also for my ac relay and now it kicks on when I have the ac button but also shuts off if it’s not on

[kinglilmoon]

Will this help keep the coolant cold, only 1of my fans is working, bought a replacement…?

[anthonys]

I just replaced my ac condenser fan, both fans work now but only when I turn on the AC. Changed both fan relays. Car isn’t over heating but the radiator fan only comes on when ac is on. Don’t know what the issue is.

Problem solved and fixed $135 later for a battery 😞

One side of my fan comes on and off the other side doesn't, and then one that does come rattles a bit looks loose.. Do you think I just need to replace the fan?

[Talicamm]

I know it’s my fan or a fuse without doing that wire test only because when I’m parked or stuck in traffic it overheats when I’m hauling ass down the highway she’s crisp 😂

I have a accord when the ac is on the ac fan works when temp switch is jumped nothing turns on put 12v to normal rad fan it works checked fuses relays etc

I have an issue with my Honda Accord, both of the fans are not working. The Diagram looks almost identical as the one we see here at 1:15 with a minor difference which I don't know what that means. On the diagram in this video there are two Relays, one on the left side (with the cooling system symbol and the snowflake symbol) and on he the right side (only with the cooling system symbol). On my car there is only the one of the left with both cooling and snowflake symbol but the one on the right is just crossed out, what does it mean? Can one relay control both the AC and Cooling fan?

I did this and the cables sparked then started smoking. Any idea what happened?

I have an 03 Accord EX and both fans stopped working. When I tested the relays doing the bypass thing, only the drivers side would spin and nothing from the passenger side. I unplugged the switch from the passenger side of the fan to test with a multimeter if it was even getting power and it showed 0 volts to that side. Is this a relay issue? Wiring issue? I’m thinking I need a new wiring harness but I don’t know

Hello, my car has this problem: the coolant gauge and fuel level no longer show and the fan does not turn on, and the fan only turns on when the air conditioner is turned on. Can you help somehow, maybe someone had such a problem. Thank you

One of my fan works but the other doesn’t. I try to hit it and give it a little help to make it spin and somehow it started working. Do you know what could be the problem?

[Donato]

I have honda 2007 k20 engine and my cooling fan only comes on when engine is warm and i spin the wheel? Any one have any suggestions swapped relays same thing

[kevinprater]

So…the replacement fans had a broken fan too?
