radiator fan does not kick on

70

Asked by skippyV Feb 07, 2018 at 12:48 PM about the 2009 Dodge Grand Caravan SE FWD

Question type: Maintenance & Repair

Hi, our car was overheating and we noticed the fan wasn't running. Checked
the fan motor with 12v, it ran high speed. Mechanic said the overheating
problem is either the radiator or the water pump. And he said we'd need a
dealership to re-program the fan. We wound up replacing the radiator but
when we turn on the car the fan still doesn't run so we don't let it run for fear
of damaging something further. I have seen the fan run when the engine is
overheating - but those moments were random and few because we're trying
not to overheat the car during this diagnosis adventure. Does anyone know
anything about "reprogramming" the fan? Or why that would even be
necessary in the first place/

Are they called something else also? I don't get any Google hits for my make/model with "fan control module".

I have an 08, I replaced the fan itself, the radiator, the thermostat, all the fuses, the fan control module...ALL OF IT. Nothing worked. Then I was told it was the brain not sending a signal to the fan to kick on, therefore resulting in the overflow and overheating. I didnt have the funds to replace the brain, so some genius grounded the wire so the fan came on automatically each time I started the van, problem solved. It has been 2 years, and just started doing it again. Im about to float this thing in the river. I have no idea what to search for in car parts to replace the "brain". someone help! LOL
