I have a 2006 f150 supercab that I ordered and was delivered 1-30-2006

Until the last month I had no problems with the truck, but in the last month
Every tine it rains, the next morning I have condensation on the inside of
The cab windows

Last week we had a ½” rain, the temperature dropped 30 degrees overnight,
When I got in the truck the next morning, there was so much moisture that
The water was condensing on the inside and running down the windows.

I checked with several of my neighbors who also have 05, 06 and 07 f150’s,
About 10 owners in all and none of them have has this problem.

All the trucks sat outside in the rain and all cooled to the same point

I have had ford trucks for 35 plus years and never had any vehicle do this

In the last month I have been looking here at the water leak issues on the f150,
I am aware that the 3rd brake light has problems on some trucks as evidenced
By the various posts.

I have looked in the normal places that I can get to.
I did the 3rd light leak test, no bubbles, did the rear window (standard 1 piece)
While I had the soapy water, no bubbles either

I felt inside the fuse panel area, no moisture.
Looked at/below rear seat, so sign

I do not hear and sloshing sounds as posted on one thread

Before I take the truck to the selling dealer, I would like to find the leak
And show the dealer where to look, it will also allow me to check to see
If they got the leak

My questions:
Some post mention looking at the door/floor channels, by lifting the door seal
Plates, how do you get them up? On previous fords you removed 2 or more screws and the channels were exposed, how do you get the plastic up without damage?

How does the kick panel on the driver’s side come up/open? I have yet to be able to
Feel there

Since some trucks per the posts, do not have any sealant on the cowling or firewall,
Is there a way to check leaks there?

I do not believe that the a/c drain is stopped up as we have had these temperature
Swings without rainfall and no moisture in the cab, also on warm days with the a/c on
There is a/c condensate dripping (more like pouring under the truck with the a/c’mon fresh air.

During the 3rd light test, I did notice some air flow from around the door handles where they move in/out of the door.

Thoughts / comments, am I missing something, or several things here?

By the way if this is posted in the wrong place, please advise where is should be and I will post there, please be kind to the newbie to the forum (not new to ford trucks)

Thanks

 

I have found some additional info on my moisture problem


THE SOURCE MAY BE THE SIDE WINDOWS AND DOORS

I was trying the soapy mixture again today and did not get any bubbles on the 3rd brake light nor the rear window

but I inadvertly sprayed the right rear door glass and instantly got tons of bubbles the same for the right front door glass and where the mirror attaches
as well as the area where the 2 doors meet

the left side does the same, bigger air leak between the doors

IS THIS NORMAL?

I used the instructions that poster "MYST" has posted to get the rear panel off to install a speaker

I found that when water is sprayed on the door almost all the water on the grass goes into and out the bottom of the door. you can watch this throiugh the plastic inner layer of the door. the plastic liner has holes and I image that the moisture is coming into the cab through the holes in all 4 doors.

I can not determine what may be entering between the doors

I sprayed the soapy misture on my taruses and no bubbles

a couple of the neighbors who have similar trucks will not let me try the soap test on theirs and the remainder of the neighbors are out of town

ANY CLUE WHAT IS NORMAL FOR THESE TRUCKS OR IS THIS A NEW PROBLEM THAT NO ONE HAS NOTICED BEFORE?

 

Please tell me more or provide a link about this "soap test". A search turned up not much more than this thread. Thanks.

 

To TFORD, I saw your response to the 2007 door question

"SOAP TEST" If you read all the various threads about the water leaks resulting from the 3rd brake light, the recommended test is to mix a mixture of soap and water and apply to the area arround the 3rd brake light, I guess I named it a bit differently.

you then turn the a/c unit to fresh air and pressurize the inside of the cab, if your 3rd brake light is allowing water in the result of the soapy water mixture and the pressurized air in the cab will cause soap bubbles to be generated arround the 3rd brake light housing

It is like making soap bubbles as a child

the same can be done for the rear window whether it is a one piece or with slider.

I was hunting the water leak for the condensation in the cab, I had applied the mixture to the 3rd brake light and no bubbles, I then tried the same on the rear window, no bubbles.

As I got down off the ladder, I have a century tonneau, I squeezed the trigger on the sprayer and that is how I found the air leaks arround the windows.

I hope this explains the soap test

On my truck the problem is that with temperature change, all the moisture condenses on the windows and it then condenses on the windows to the point that the windows begin to sweat on the inside.

Indication is that there is too much moisture inside and it then condenses with temperature changes or cooling at night

my supercab has the clear plastic sheet glued to the inside of the door between the metal and the plastic inside of the door in the cab
this glue looks like a tar like mixture.

the design used is reall not moisture tight, there are alot of gapsfurther up the door for the cables and wiring.

I am going to have to pull the panel off all the doors and see if one is like yours without the clear plastic.

I want to stop the moisture, the way these doors are sealed allows moisture into the cabin.

So far no one will let me try the soap mixture on theirs.

I am curious as to why this has started happening in the last 2 months

I have never had this occur on any other vehicle

if you have any better ideas, please post.

with all the threads about water leaks, I would have thought that someone would have noticed the air leaks arround the windows and doors

 

In my other post on this related subject, I concluded that the situation I have is normal and not problematic. That is, water runs through the door and out the bottom by design.

I never ran this soap test, but thanks for the info. Who knows if I'll need it in the future?

It sounds like something is definitely wrong in your case. Do you leave the AC switch in the Max position, or leave the Recirculate button on? You should make sure both of these are off so that the truck can breath when it's parked. I have noticed that if I forget and leave these off on a rainy day, the inside of my windows will be fogged when I get in the truck. Maybe you're just experiencing an extreme case of this because of where you live.

Good luck getting to the bottom of this.

 

Check out my post :" 2006 passenger side water leak".
Water was condensing in my truck also , from the wet carpets / insulation and water in the door sills .

 

If your vehicle has the factory Sirius installation then the Sirius antenna on the right side of the roof could be a source of leakage as well. Bead of silicone and then reseat but be careful not to damage the wire connections if you use it. Had two leaks that showed up this past winter - the Sirius was warranted by the dealership as a bad batch of seals, but the 3rd brake light was not.

 

Wow, you guys know that this is a thread from 2007 right? Check dates...........
