Ford A/C :: 2012 F150 - Windows Won't Defrost?
Feb 3, 2013
My windows do not defrost. Blows hot air and seems to blow out defrost vents ok. When I bought the truck last winter no problem untiL A /C would not cool cab in summer. Now it's winter and no defrost.. I have takin into dealer and they said compressor is kicking on ok but still no moisture leaves the cab. It is dry here in Kansas so when we get rain I will have to sponge the windows.

I have a '90 F150 without A/C. For some reason the healing system is stuck on defrost. No matter where I turn the selector switch ( floor, vent, etc) air only comes out the defrost. If I turn it to "off" it will turn off. What is wrong?

I have a 2003 Model F150 4x4 that has always ran good for me, and has only had minor issues ever since I've had it. Not too bad considering it has 266,xxx miles on it and running 100 miles a day on the original motor & transmission.
Here's my problem - my air conditioning will only blow thru the defrost. I can hit vent on the control panel and it will blow thru the vents, but if i hit max ac it switches to defrost. I live close to Memphis, and it has gotten super hot around here and i really need this to work correctly. I have looked under the hood looking for messed up vacuum lines but haven't seen any that looked bad.

My A/C is blowing cold but only thru the defrost vents. First it was blowing normally from the dash but during acceleration or under load, the a/c would randomly blow from any vent, from the floor, dash, defrost. Now that stopped and it only blows from the defrost vents above the dash-board.

I just picked up a 78 F150 Ranger XLT with a 351M in it this past friday. I am absolutely in LOVE with her. She is a great solid truck. One issue I am having though is that she blows hot air out the vents over the hump but nothing is coming out the top of the dash. I am guessing that i will have to take the dash off and clean out the box check the door etc. What did you do to rectify?

Seems below 20 my car cannot defrost the windows or heat the cabin. It has been 0-10 the last couple days here in SE WI. The coolant temp gauge is straight up right in the middle. Some how coolant isn't flowing through the heater core. Could this be a design failure? It doesn't seem to matter what settings are on dash. I have tried with ac on and off, recirculation on and off, full defrost on, fan on all speeds, have also tried a combination of cracked windows open.
Are other people experiencing this as well? Is a call to the dealer in order?
For ref car is 2014 tdi se with 34,000miles.

I thought I wouldn't have need of the defrost for several months yet, but today we had unusually cold rain and my windows soon fogged up. The fan (not a/c) was already running at a very low setting (one or two clicks only) when I depressed the defrost button. Roughly 15 seconds later, it was like a hurricane in the cabin! The fan moved to the highest setting all by itself. This did clear the windshield in seconds, but it was a bit disconcerting. This phenomenon repeated itself all three times that I engaged the defrost button. Is the defrost supposed to do that? I swear, the sudden change startled me so much, I hit my head on the ceiling of the cabin...

After not starting my car following several days of extreme cold, my battery died a couple of weeks ago, and after boosting the battery, I noticed a couple of electrical accessories (power windows, rear defrost, rear brake lights) are no longer working. I was told by a mechanic at the local Wal-Mart that it was possibly the main relay, which I replaced at the dealer, but that did not fix the issue. I've checked the individual fuses for these accessories, and all of them are OK. How to troubleshoot this?

I have a 2012 super duty with a 6.2 in it. I bought it last winter and noticed no air getting to the defrost vents. Now in the heat, sometimes when I turn the air on, all I get is super hot air like the heater. Sometimes playing a bit will work but not always.

I have a 2012 F-350 SRW with a 6.7 diesel. The other day I went to push the defrost switch and noticed it does not work. All the lights work in the switches, and the temp control works, but no matter what I push, defrost or floor, it stay in the vent only. Anything I can check??

I have 2012 F150 5.0. Was going to do some errands yesterday. Got 3 miles from my house and all of a sudden the transmission would shift from say 5th gear down to 2nd. Then it would shift up to 6th then back down to 3rd. It was shifting all over the place. I did shift it to manual it seemed to stop it a little. But then it would shift by itself again .I went directly to the nearest Ford dealer. I did not shut it off, so if there was a code there they would see it... No codes. The Ford dealer will look at it. Any thoughts?

My 2012 f150 AC is blowing out of the defrost for a couple of minutes on start up. The AC will begin to blow out of the dash vents then will switch back to the defrost vents before blowing out of the dash vents for the remainder of the trip.

I've searched all over and can't seem to find the answer. When I pull the tail light out of my 12 F150 there is a blue/wht wire and a black wire going to the back up light. I assume the blue wire is the positive and black is the ground. Is that correct?

a buddy of mine has a 12 F250 that he bought new and is ready to add power locks and windows. I know we can get some aftermarket kits for both but he wants to use the factory door panels and switches from a power setup. I am sure we could use the factory window regulators and panels and just use and aftermarket wiring and flush mount switches. I had figured the wiring might be in the jambs but not in the doors, but when I pulled the trim back, we didn't find any extra wiring going to the rear doors, its a crew.

It rained really hard yesterday. This evening I got in my car and the windows were all wet on the inside. While I believe some moisture is normal this was ridiculous. Where to check/look or what it could be. I checked the sunroof and under all the floor mats (not under the carpet; just mats)..

I just recently noticed that 3 of my 4 windows will not go up or down. Drivers side OK. Recently had the recall done for the passenger seat sensor, but I can't recall if I exercised the windows after. I am thinking maybe the master switch in the driver's door could have died. 2012 Camry XLE ...

My wife's 2012 Prius C's windows pull away from the wipers when opened. As a result, all four windows will not clear the condensation or rain drops while opening, I have to get a squeegee and clean the windows manually. I have never owned or seen a car that had this problem. Went to the dealer and checked a new Prius C on the lot, looks like a design flaw since that car had the same problem. Any comments?

I have heard that there is a way to program the FOB so that when you hold down the UNLOCK key for a few seconds the windows and sunroof opens.
is there a way to program this ourselves? Or is this only available at the dealer, and if so, will there be a cost associated with it?

Yesterday I was driving home from a long road trip (1425 miles in 2 days) and I was listening to my stock radio/speakers. It was a bit chilly with the front windows down, but too warm with them up and I didn't want to turn on the a/c. (no specific reason. I just didn't want to). So I thought I would just open the back windows.
As soon as I did this, the radio bass was just shaking the whole car. It was nuts. I wasn't even listening to anything with a strong bass to it. I closed the windows, it went away. It was better when I turned off the super bass, but I found this odd. Especially since I see people put these large speaker boxes in the trunk.

I noticed that after turning off the ignition I could still operate my power windows for awhile. Why would this be?
