I have a 2006 c230sport, its been in a wreck, front end collusion. had to replace all the radiator support brackets, radiator, headligts, bumper and hood. the problem im having is when i start the car the radiator fan kicks in high right away and stays on, even if u turn it off with key. i searched the forums still cant find help.

Check your temp sensors.

thanks.. I will try that. U think not having any freon in the condenser can cause that problem?

It might be true as well. I know when your over charge your freon system you fan usually kicks on and off repeatedly and makes a hsssing noise inside the car.

I have never experience low freon. Have you try recharging the system to see if that sovles the problem? I'm pretty sure they installed in a new condensor if you had a front end repair. If that don't work, then double check your temps sensors/swtiches.

Does it happen when you have the A/C Switch on or off?

my a/c doesnt work at all, because the pigtail connector that plug into the condenser is broken i guess it plug in to the refrigerant pressure/temp sensor, after the repair the ac dint get recharged..

When you say check the temp sensor, is it the coolant temp sensor wich sits in front of the engine?
