Ford Excursion :: AC And Defrost / Vent Switching Back And Forth
I have to once and for all try to figure out what the heck is up with the AC and the defrost/vent switching back and forth. I have searched and searched and posted a few months back as well. But now that it's summer and 100 degrees out I've had a chance to test some more.
1 - I replaced both hoses going to the hubs up front.
2 - I am not sure how to test vacuum, but I did cap the hoses that lead to the hubs and still had the fluctuating back and forth
Looking for detail how to test for vacuum leak with a gauge directions ? What number is supposed to hold on the gauge and for how long etc...?
3 - It used to be that when I got to a high speed or RPM it would shift to defrost, but now I've noticed that once on the freeway going to work for instance and doing a constant 55-65 ( sub 2k rpm ) for about 20-25 minutes the vents hold fine. When I start to stop and go with higher RPM's it starts to 'break down' again. Could it be that there is a vacuum canister or pump ? I don't know ?? The diesels have a vac pump - do the V10's ? What can I check if there is no vacuum leak - what's next ?
Ford Excursion :: A/C Seems To Only Blow Out The Front Windshield Defroster
I'm having with my Ex. When I have the A/C (or heat) on, it seems to only blow out the front windshield defroster. Once in a while it'll blow out where it should, but 99% of the time it only comes out the defrost. This is when I have it on face, face/feet and feet.
View 6 RepliesFord Excursion :: Rear Defroster Tab Has Popped Off The Window
So the rear defroster tab has popped off the window. I purchased this kit from O'Reillys but when I clipped the wire back onto the tab it popped the tab right back off. I even waited 48 hours instead of 24 so it had plenty of time to set, even with the cooler temperatures. Okay, so I forgot about it until I took the stroller out and noticed the trim laying in the back of the X... but still, plenty of time to bond well. I'm thinking of calling a glass shop & seeing what they'll charge to reattach.

Today im driving along in my 2000 X v-10 limited and had the AC blowing on high. All of a sudden it started to blow out the defroster vents, then back to the correct dash vents, then back and forth intermittently.....No vacuum leaks that I could find.. Is that controls what vent doors open to control air flow?

2005 Excursion..... When the switch is pushed, the relay clicks. The light on the switch does NOT come on.
I have switched relays for testing. The fuse is good. The truck has heated mirrors. Are they related to the rear glass issue?
Bought this in June. No winter use yet. Is a freezing temperature required for operation?
Ford Excursion :: 2003 - Rear Window Defroster Does Not Work?
2003 ford excursion xlt, 4x4, v10, auto.
My rear window defroster does not work. I have no power to the switch. on the reply I do have power to terminal 30 on the relay. If I use a jumper wire between 30 and 87 it works. I think the problem is terminal 86 should have power when thever key is in run position but it doesn't. I have the factory wiring diagram book but am at a loss. It seems to me it is more of a mechanical connection inside the junction box but there are other components on the circuit that work.
Ford Excursion :: 2003 - Turn Signals Stopped Flashing / Front AC Now Only Blows Through Defroster Vent
I have a 2003 Excursion 7.3 2WD Limited and all of the sudden experienced a number of issues all at once.
1. Turn signals stopped flashing (hazards still flash)
2. Lost Rear back up sensors
3. Lost overhead trip computer
4. Lost Rear A/C - switch does nothing
5. Front A/C now only blows through the defroster vent
I've checked all the fuses and cant find any bad ones.
I replaced the multi-switch flasher and turn signals still dont work - only hazards.

Ford F-150 (2009-2014) :: Rear Defroster Not Working?
For the second time in the last 24 months, my rear defroster doesn't seem to be working. The first time I took it into the dealer and under warranty, they had to replace the entire rear window. The side view mirror defrosters still worked and they still work now. It just seems that the rear isn't working again and this time my warranty has run out.
Should I take it back to the dealer and hope they honor their work? My 3yr/36k expired 4 months ago. How could I even test that it is working? I've only had to use it 2 or 3x since last Feb. and that's when I noticed it doesn't seem to be working. I only had to use it for short trips so the main defroster in the cab eventually defrosted the rear window. The weather is warmer so now I won't have as many chances to have it fogged up.
Ford F-150 - 1997-2003 :: Air Conditioning Comes Out Of Defroster Vents

View 9 RepliesFord F-150 - 1997-2003 :: Heated Air Coming Only Through The Defroster
1997 F-150, 4X4, 151K miles, 4.6L. For years I've had an issue with heated air coming only thru the defroster, never the floor (a/c works normal). I've searched the forum and read many posts regarding the blend door. I pulled the switch and tested the vacuum hoses by taking a can of compressed air and blowing into the lines. All seem to be working with the exception of one, the black hose. I tried to follow it but short of removing the entire dash, I lost it. I read that there is a canister and small module in the engine compartment. Is there a way to test these to see if they're the problem? Where to look ? I only see one, on the firewall, passenger side, between the fender and the center of the compartment. Where's the other?

So, my 06CC V10 likes to switch to the defrost at times while I'm towing, usually above 65mph, would that be a vacuum issue? Also, the truck seems to always have hot air blowing in to the cab somewhere from the fire wall? Lastly it seems to me that the steering wheel has a lot of play in it (left/right) before the wheels actually turn, should I tighten up the steering box, or is this normal.
View 4 RepliesFord Super Duty (1999-2016) :: A/C Blow Through Defroster Only When Hot?
2006 Harley Edition F250 6.0 Diesel
When temp outside is around 75 degrees or cooler blows and switches between different settings as normal. A/C will blow hard thru dash vents and freeze you out. When it gets hot outside it will only blow thru defrost!!!! So on wat to work in morning everything is perfect - driving home from work when it is 100 outside it only blows thru defrost (cold cold air though).
Confusing the heck out of me because a vacuum leak doesn't care about the outside temperature.......

I have a problem with my 2003 Ford Focus ZTS. It has a 2.0L ZETEC engine and is automatic. I recently replaced the Starter, Alternator, and battery cable because the car was having some current issues. All parts are brand new, non-refurbished. The car cranks fine but is now sputtering. When I drive it, it seems like it has a hard time switching out of first gear and and will hit 3-3500 RPM before the gear shifts.
