Might be a newbie question, when I turn the key to acc or on, my radiator fan seems to be running on and off, is that normal? I replaced my oem battery since I couldn't start the car w/o turning off all my other electrical accessories. I can start the car with ease now but the problem is still there. Anything to do with fan control or relay? The stock ecu was tuned once at a shop with some aftermarket bolt ons, that's about it.

 

sounds like it's the "eletrical gremlins" your fan shouldn't be coming on at all, unless you have the A/C on

 

I did a search and came up with a similar problem with lancer,

I think I'm gonna order the fan module ( #4 ) in the picture shown below from autocenter.net

 

I have the complete assembly used if you want it make me an offer

 

Just interested in the module. pm me with the price shipped if you would like to sell it separately.
