2008 civic cooling fan wont work which fan cools the engine? i put 12 volts to the one on the passenger side and it works. i started car and turned ac on max,neither fan turns on. i jumped out the fan switch,still no fans came on. i tried a new relay,no fans came on. i am not sure what fuses are used under the dash or under the hood for the cooling system. thanks |

Then I'd get a wiring diagram if I thought there was a problem. What problem are you chasing? Overheating? Is the check engine light on? Got codes? |
Re: 2008 civic cooling fan wont work not sure if the compressor is coming on. its 25 degrees here. the switch that is on top of the thermostat. the cooling fan relay i think. where would i get a wiring diagram from ? |
Re: 2008 civic cooling fan wont work temp gauge has been on 8 bars lately,it used to be on 3/4 bars |
Re: 2008 civic cooling fan wont work Temp (25F) is too low for the AC to run unless you have had the engine running long enough to put some heat into the AC system. Fans won't run until the compressor runs. That is not a fan switch. Don't ever just short connectors unless you know exactly what you are doing. The car does not use a coolant temp switch to run the radiator fan, it is controlled by a temp sensor now. Shorting wires for a sensor can ruin the computer. Open the radiator cap CAREFULLY and see if the antifreeze level is low. It should be full to the top. Got a check engine light on? Codes? Got a way to read live operating data from the computer? |
