Defroster Question

3124 Views 12 Replies 7 Participants Last post by  JaxRidge
Is there something beyond pushing the defroster button I am suppose to do to clear my windshield?

This morning I had the A/C on, and I had defrost selected, but after 10 minutes, my windshield still was not clear. I also noticed that the left vent, the one by the door was blowing air as well. I reached up by the windshield and I could feel air flow to the windshield, but like I said, it wasn't doing a very good job.

Are you sure the "frost" wasn't condensation on the outside. It's got to be miserably hot and humid in Florida this time of year. If the AC is blowing cool air on the inside of the windshield you will get condensation on the outside that the defroster will never get off. Turn the defrost off and use the wipers! Defroster mode is made for condensation on the inside when it is colder on the outside of the windshield.

Yea, it's hot and humid here. Pretty normal stuff for us.

Yes, for the most part it was condensation on the outside of the window. My Pilot would clear it up in less than 2 minutes. I guess it's about getting the windshield to a temperature where it's less likely to hold on to the moisture, more than actually defrosting.

There have been mornings that even with my Pilot I had to play with the settings until it cleared up. I guess I'm just a little hyper critical since I had a problem with my battery.

And to be honest, I haven't had a chance to read the manual yet, so maybe I'll find something in there that might address this issue.

Thanks!
Wherever you are, the defroster on any car always works better when warmer air is used to "defrost" the window. Try turning temp on A/C up a bit to warm the window then return back to chilly air for your trip.

Thanks! Will do.
make sure your "mode" selection is set correctly to the defrost icon. then air will flow from dash to windshield........the air also will blow through the far side vents. that is so you can move the air flow to the side windows for defrosting.

Just park it in the garage :D :rolleyes:
Yea, that would help, but then my wife would not be too happy. I'll let her keep the garage. :)

Okay, maybe I missed something. I thought I just press the "defrost" button and let it go. (That's how my Pilot worked.)

I need to finish reading the manual. :rolleyes:
I'm curious, does closing the vents to the rear force more air up front? Or are they off in defrost mode?

Good question. I noticed that the air going to the windshield was not blowing as hard as I expected it to be.

I'll play with it again in the morning, as I'm sure I'll have the same conditions as I did today.

A little bit of a tangent, but since you mentioned the rear vents, I've noticed that when I turn the rear vents to "off," I can still feel air being blown through them. Not as much air as when I set them to "on" mind you, but still some nonetheless. Anyone else get this same behavior or do I have to go to the dealer to tighten something up?
Update:

Defroster works fine. Operator error. :rolleyes:
