Car Should Not run those fans/blowers all of the time.
Only w/ AC On or someone modified or shorted out the control circuit that turns them on.
Many fools mod the control circuit because has coolant problems and now fan Force On Hinds whatever is wrong.
See my Cave, Rad Fan
Rad fan and engine blower is Not meant to be On full time and have a shorter life if force on..
Rad fan motor can find replacements but not engine blower.
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
