Ford Excursion :: 4 Wheel Drive - Vacuum Seal Is Out
I have an 02 4x4 excursion. How can i tell if the 4 wheel drive is working? If I turn the switch I dont feel any change. Also sometimes I hear air coming up near the defrost at the base of the windshield which makes me think maybe the vacuum seal is out. Also how can I check/change the hubs between manual and auto and what applications would warrant switching them?

I have a 2000 F-150 4x4 and the four wheel drive isn't working properly. It does work,but to get it to engage I had to drive in reverse for a couple feet then it locked it and everything was fine,pretty sure that isn't normal. What could be wrong with it? As soon as I turn the lights up on the dash,but the front tires don't spin.

My 4 wheel drive is not engaging on a 2001 F150. The indicator lites on the dash illuminate to suggest that the truck is in 4 wheel drive but sigh...it stays in 2 wheel drive. No gross sounds and the indicator lights are not flashing. Could this be a fuse or a relay issue of some sort. What else should I try?

I recently picked up a '99 F250 Super Duty with the 6.8L V10 for a song.
The 4 wheel drive hubs are not working with the vacuum. If I use the manual lock on the hubs all is well. I ordered the Innova 31703 CarScan OBD2 + OBD1/ABS/SRS Scan Tool. It says it does Trans codes. I am hoping it will cover the 4 wheel drive too.
Maybe related, the heat is always on. Meaning I feel heat at my feet when the temp dial is cold and fan is off. I can't find the heater control valve to check the vacuum line.
Ford Excursion :: 2003 - Wiring Diagrams For Lightning System?
I have a 03 Eddie Bauer PSD and I'm looking for wiring diagrams online. Specifically for the lighting systems. I bought a set of OEM telescoping, heated mirrors with turn signal and running lights and the running lights do not work. Appears that 03 may not have supported this but I see other rigs with the same mirrors and the running lights working.

I have a 2003 F150 supercrew 4x4 and I'm on my 3rd - 4wd vacuum actuator this winter so far. Somehow water is getting into the actuator itself mounted on the axle and then when it gets cold enough it freezes up and won't work until the heat from the engine thaws it out and then the 4x4 will engage.
Every time I've changed it I have found the part to have about a quarter cup of water in it. and can't figure out where the water may be entering these things. There also was no moisture in the vacuum lines when I blew them out.
I've been using the Dorman brand replacements from O'Reilly, they have a lifetime quarantee but I'm sick of swapping them out every month...
Ford F-150 - 1997-2003 :: Vacuum Controlled 4x4 Not Working
I'm working on a 03 Lariat F150 with vac. controlled 4x4 (I'm new to this one). Transfer case works, ft drive shaft turns, but the front axle wont engage. The servo works, and the linkage is tight on the shaft, and the shaft turns back and forth, and the ft axle can be engage manually by working the small lever back and forth with the servo disconnected, but when zip-tied in place it doesn't stay in 4x4, so something is broken, worn out, or disconnected inside the housing.
Also I repositioned the servo back a bit with a spacer to make sure it wasn't a length of travel issue, and is not - the problem is definitely inside - the linkage feels sloppy when manipulated with the servo off.
Since Ive never had one of these apart I thought Id ask first (also a new thing for me), so I'd know what parts to get (I don't live "in town"), and I figger this isn't the first one of these to break. So I am sitting down - what am I in for??? It looks pretty straight forward, but somehow I doubt it is...

Ford F-150 - 1997-2003 :: Grinding Then Thumping Going Into 4wd - Vacuum Solenoid?
I have 97 4x4 f-150 V6 4.2 litre that in 2wd tries to go into 4wd causing a grinding then a thump. When I put the truck into 4wd there is no grinding or thumping.
I believe one of the vacuum solenoids could be bad. Just was wondering which one would cause it to want to go into 4wd while in 2wd. The left most solenoid looking under the hood is the 4wd and the other with the pink vacuum is the 2wd.
I have no vacuum from the solenoids but from the lines going into them.
Ford F-150 - 1997-2003 :: P0401 Code - Vacuum Lines?
So here's the background. I recently bought this truck. It's a 97 Ford f150 4x4 4.6l 99w vin code. Anyway Driving it home got a p0401. No problem. I Applied vacuum from other vacuum source to EGR engine stalls. So to me passages are clean in the throttle body. I checked to verify and indeed passages are clean. No while doing so I noticed no vacuum was making its way to the dose valve thing. Strange.... So took the line that runs to the passenger fender to dose off and it was impossible to blow air through.
So I cut out the clogged section found solder in the line. I filled the gap I now created using some 5/32 vacuum line reconnected to test and to my anvil still not vacuum. So I disconnected it again. Went directly to where the yellow/orange dose vacuum line connects to at the passenger fender and to my surprise no vacuum there either. No my question is. Am i suppose to have constant vacuum to the dpse or I'm I just being an idiot. And two if I am suppose to when the vacuum line runs into the passange fender where does it go from there and could I have a major issue in my hands?
Ford F-150 - 1997-2003 :: Vacuum Leak When Engine Is Under Load
It has been since the 80's that I have attempted to do any work on a vehicle. How do I find a vacuum leak and where is my vacuum canister. I am assuming that it is a vacuum leak for anytime my engine has a load on it the air stops coming out of the dash vents and goes to the defrost vents. I have an 2000 F150 with the large engine with about 112,000 miles.
