Cooling Fans are on


Recommended Posts

Folks, I noticed a few days ago that I had a major cooling fan noise in the front . Now I have noticed the fans are on even with the engine pretty cold ( say a few minutes after I start the engine). I checked and both fans are blowing air at a very high rate of volume out in front of the front wheels.

I also noticed about 1 week ago that the warning light ( rear spoiler light) went on for some time and then switched itself off ( have not seen any unusual behavior ie it come on at start and goes out within less than one minute). I am mentioning that just in case there is a connection.

What can be wrong??

Now that would be an interesting system. I assume you have a compressor providing you with the "cold" air ( ala fridge/freezer system)and I would assume you have the internal fans ( in the dash) that would circulate that cooled, cold air. I would also assume that the two fans in the front are there to cool the water in the front radiators ( and maybe move the air away around the brakes although that air would heat up the brakes rather than cool it?)

Today is Tax day and not April fools day. :thumbup:

He is correct. The climate control in the normal mode and temp above I believe 37F will have the air condtioning compressor on. The fans turn on to cool the condensers that are mounted in the front behind the coolant radiators.

You can turn off the compressor by pressing the button on the climate control with the snow flake on it. In a few minutes or so the fans will turn off.

Ahhh!! Now it makes sense, the fans are cooling the condensers too. As I am in California, I always drive with a/c on ( never noticed the fans coming on soo early / soon after starting the engine, of course I understand that they would come on when the engine is pretty hot). Thanks to the both of you!!
