Electronic Climate Control Question

1355 Views 8 Replies 5 Participants Last post by  sfblacksel
I have a 98 taurus se and have always wondered something about the electronic climate control. I always just leave it on auto. However, one day i was curious if i hit the max a/c button would the car cool down faster. So i did but i didn't hear any difference in the fan noise. On my other taurus that i had (and any other car i've used max a/c) when max is turned on, there's more noise from the intake fan turning on. Does auto automatically use max a/c or what? Also, it seems that my outside temperature sensor is now off by 5 degrees or so. I know it's on the dash up by the windshield. Is it possible that it's just got dirt or some armor all on it and that's messing up the reading?

The Auto function will choose the best way to reach the desired temperature depending on conditions.

For example, if you need the A/C to 70* it will kick on full max A/C until around 71* then slow the fan, after that it will go to norm a/c. And maintain that temp.

Hence the EATC system being a set and forget.
