radiator fans only run with a/c on.
I have a 2004 bonne se and my fans quit working,engine lights came on. I changed the cool fan 1 and 2 / hvac relays under the hood and still no good. I then got a new thermo and sincere below it put it, Still no good, only way the fans run is if I unhook the pigtail to that sincere or turn the ac on. Any ideas?

Fan 1 comes on at 219* and turns off at 212*. Fan 2 comes on at 228* and turns off at 221* If you had a worn out thermostat and the engine was not heating up to full temp the fans wouldn't turn on. What temp thermostat is the new one? A 180* or a 195*?

I'm thanking its a 195, before I put it in my gage out not reset back at home and start at 200, now they are normal. When we ran the codes it came up as bank 1 and relay/thermo, he said it was good to clear it out after the new parts.

If that parts have been replaced, then yes, reset the code and see if it comes back.

Thanks for the help, I let the car run for about ten min and they came on for a few then off again, so I'm thinking its good?
