Quadcammer

I have my car set to auto and 70 degrees. When I get in my car its usually very cold, and about 3 minutes before I get home, the engine temp is normal.

However, the car never seems to increase the speed of the fan as the engine comes up to temperature.

It always seems to stay at level 1. If you push the up button, it goes up accordingly, but it won't do it automatically.

fan regulator problem?

Thanks
