Default Front windshield defroster is not working

So i went to pull my car out today, and my front windshield had alot of steam on it, throw on the defroster, it doesn't blow any air what so ever. On all the other settings it works fine, just not the windshield. I pulled the fuse, it looks good, I even put it a different one, and same thing happens.

This has never happened before, what could be the problem.

TIA

And also on top of that.. Every setting blows the same air flow, my center vent above my radio, no matter what setting it's on will always blow air through it. How do I fix this? Please help.

well if the blower works maybe something is cloging it or some how the button you press to use it isnt working? no air comes out at all?

No, air does come out just not out of from what I can tell the feet one, and the one that would defrost the front windshield.

Yes, but I believe every EG works the same way when it comes to the climate control.

got a helms manual? possible problem sounds like the Mode Control Motor. it's the motor that gets the info from the heater switch panel. and that decides where the hot air needs to go.

Here's a few things to check:

clogged heater duct
clogged blower outlet
clogged heater valve
faulty air mix door
heater valve cable adjustment(I doubt it)


BTW I'm pointing to either the heater control panel itself or the Mode control motor as the culprit. check the continuity of both. if either one do not have continuity that is the cause of your problem.

check the blower box controls, by lower right driver side, right behind the center console?
