Hello guys. This is my first post & of course it's a Millenia problem.
Well I bought the Millenia (2002) 2.5 for my wife & it's been great until recently. The problem is the car runs fine when it idle or driving. The overheating happens when she turns teh ac on. At first it would shoot up as soon as you turn it on. I replaced the coolant temperature sensor & at first it seemed to do the trick but as soon as we got in traffic the temp starts to climb.
The ac fan works fine but the main fan does not. When you turn the ac on when the car is running both fans kick on but in about 6 seconds the main fan cuts off.
My question is how many people have had this problem & how do I go about fixing this?
Thanks for the help.[/b]
I Had the same problem and believe me i did spent a lot on it, changed the radiator, water pump, temperature sensor, and what have you regarding the cooling system, except for the fans that i didn't change. Out of frustration, i kept checking every where within the engine compartment and just recently, i was messing with the wiring around the fuse box and found a short circuited wire. Lo and behold, i straighten out the wires (cutting and joining where necessary) and i can tell you that i am so proud of myself (though have spent a lot of money), i finally fixed the overheating in my 2002 Milly and enjoying my Milly once again. I dont know how curious you are when it comes to things like this. i got tired of spending money and decided to take it on myself. so, with my experience i will say that you check for short circuit (making sure that all cooling components are in good working conditions) , which might be cutting off power, or not supplying enough power to one or more components of the cooling system and hence, overheating. Good Luck!
