Over the last 3 years since I've had my car, the aux fans have always run on full, constantly, regardless of weather conditions even from a cold start in the winter. This past month my a/c charge was very weak so I had it recharged.

Other than noticing that the air was much cooler, I noticed that the aux fans aren't on as often now. I mean it sounds like its running as is required by temperature, not as it was before.

I've tried everything to diagnose the "always on" fan problem. It seems like an a/c recharge solved the problem. Does this make sense to anyone?

Thanks
Mike
