    radiator turns on befoe I even start the engine?

    This morning I was cleaning my interior and put the radio on, turning the key to the last position before ignition. I had't driven the car at all and the engie was cold, but the radiator fan started blowing. Has anyone else experienced this? It semed fine once I started driving, it wasn't even hot today, 75 tops. Thanks

    Is the two green connecters (I think there both green?) plugged up?

    I believe it go,s into a kinda test mode, Peek under the dash at the bottom under the steering colum and check em out.

    Otherwise.............I dunno

    if the car is driving normally, it's not the green connectors.

    they put the car into limp or diagnostic mode. leave them unplugged.

    that has nothing to do with the radiator fans coming on.

    was your A/C or defroster on? i would suspect you were hearing that.

    I opened the hood before I started the engine and I saw it was definetely the radiator fans. I'm not going to worry about it since she's driving fine. thanks for the feedback guys

    I'm a moron. It was the front defroster, apparently it automatically turns on the AC. If anyone else has this problem, this is probably the reason. I thought the car felt sluggish the last few days!

    Just remove the little microswitch and you can run the front defroster without it kicking in the A/C.
