Ford Excursion :: 2001 EX 4x4 Works In 4Hi / Won't Engage To 4Lo
Jan 23, 2017
The Transfer case motor works fine changing from 2H to 4H and back to 2H. Verified the drive shaft is locked in 4wd. Drive shaft is free when switching back to 2H. Hubs work fine and no problems on the vacuum side. Garage is 50+ degrees.
Very occasionally I can get into 4 Lo. (Neutral - complete stop - brake pedal depressed). My main question is could the Transfer case motor be bad if it works in and out of 4H with no problem? I have not seen any answer to this question from my searching. Also, could the dash switch be going? Last summer this started and now seems to be getting worse. This weekend I could only get into 4L one time. Where to start checking (motor on transfer case or dash switch or other)?
I have tried rolling slowly, backing up etc... Problem is I can easily hear the motor work when going to 4H and going to 4Lo (when it is working) most times when it is switched to 4Lo, there is complete silence like there is no power to the motor at all. Tapping the motor does not work. I pulled the electrical connectors off the motor and all pins on both plugs look clean and new.
Thought to first check the dash switch but not sure how to check it. The motor could be also a problem? Is there a way to remove the motor and check it?
I want to get this fixed by the spring since I use 4Lo every weekend when launching the boat. (Never has been deep enough in the water to get close to the Transfer case)..

I bought a 2001 Excursion Ltd 4 years ago. A previous owner put Warn Premium hubs on it, which I would have eventually done myself.
I got stuck a couple of weeks ago and tried to use my 4wd. Nothing.
A friend suggested I replace the Transfer Case Motor as it can go out if you don't use it. I got that done today but I still don't have 4wd.
I can hear the transfer case shift and see the drive shaft spinning, but the front tires don't spin.
I thought it was the PVH solenoid, but discovered the Warn locking hubs don't use the vacuum and it has been disconnected/plugged.

Monday I started my truck after leaving it in the garage while on a 8 day vacation. Shifting into reverse led to almost no movement at all. After a few seconds, I shifted back into park and then reverse again and got a solid reverse right away. I may have noticed sluggish shifting into reverse previously, but not this noticeable. What could be the culprit?

03 Jetta 1.8T AC is giving me fits. When the compressor comes on the AC is nice and cold. Problem is that it isn't on very much. Today was a good example. No AC for about the first 30 min drive to get an oil change (local driving). Next 40 min highway drive, AC only got cold for the last 20 minutes and then started to warm up before I got to work. Drove to auto parts place at lunch, AC cold from start to finish. No AC all the way back to work.
So, this evening I started the car with the hood up and watched. Compressor wouldn't engage. Pushed the AC button a couple of times and clutch engages. Compressor stayed on for 7 minutes and ice cold air. Clutch then disengaged and immediately both fans went to high speed for about 5 minutes with warm air out the vents.
Fans cycled back to low speed and compressor clutch engaged again for about 2 minutes this time. Fans to high speed again for 3 minutes, then compressor engaged for only a minute. Each time the compressor shut down, both fans would go to high revs. The minute they would go to low speed, the compressor clutch would engage and I'd get nice cold air..
Just had the expansion valve replaced and r134a charged by and AC shop last week. I have had the on/off AC problem for months and then could not get the compressor to engage at all for about one month. Of course, just as I was getting to the shop, it started blowing cold air.
Not sure whether I'm looking at an electrical problem or what. Just seems odd that both fans suddenly speed up and slow down and the compressor engages only on low speed.
The only other odd thing I've noticed is that cold or hot, as soon as I turn the ignition on (engine off), one fan continually starts cycling on and off. It does that continuously. I've checked the fuses on top of the battery and they all look fine. No appreciable drop in RPMs when the compressor engages. Fan control module?

I am having a hard time figuring out what is going on with my A/C. First time you start it for the day, works great, blows cold air, but will only do it for about five minutes, then the compressor kicks off.
I have tried by-passing the high and low pressure switches, compressor still will not kick on. Checked the air-gap, it is fine, and I actually removed the shim, so there is almost no gap at all now, didn't fix the problem.
I tried replacing the A/C clutch relay, no luck there. I can tell you that if I manually push the contact in on the A/C clutch relay, the compressor kicks in and runs.
The only thing I can think of at this point is the A/C control panel in the dash, but wanted to check before I buy that expensive part and replace.
If it matters, this is on a 2000 Excursion, with the 6.8l v-10

My A/C works fine when I am moving, but when i come to a stop it does not come out cold.

I have a 2000 excursion v10 with 66k miles on it. This past weekend i went to engage my 4wd and it would not work. the light on the dash is on and i think i heard a click but no luck. A buddy told me to tap the transfer case motor with a hammer but am a little skeptical. another friend told me to check the vacuum switch with the vent/ defroster but i am not sure that holds true with my yr/model (i did a test where i left the vent setting on face/feet then turned on the 4wd. the airflow seemed to remain as set). About a year ago i removed, regreased and repacked my front hubs.

I am a new manual 4wd system. i have a 02 excursion. i have tried to turn my hubs but they don't seem to move. i am unsure how to engage the system.
Should I put the hubs in the lock then put it in 4 wheels hi or low or the other way ....
Now from reading some of the forums it may sound like my locking hubs may be frozen and need replacing ....
Any good set of locking hubs and can i rebuild my sock ones for spares. its there a step by step on how to replace the locking hubs ....

My front heat controls work at start up occasionally. The heat will eventually come on in front after 15-30 minutes of the truck running. Needless to say this sucks for defrosting the front window during warm up. The rear controls work fine. I do have a couple that need replacing but the fan control isn't one. Temp & selectors. I've searched but haven't been able to find anything about same issue. Where to start?

I've noticed that when I lock the truck, the rear hatch stays locked most of the time. I have to manually lock it with the key if I want my truck to be secure. When it does work, it doesn't sound weak. When it doesn't, it's silent. Where should I start looking?

Cuz then there wouldn't be nothing wrong with my radio. So my factory 6 disc stereo has been giving me guff. Sometimes when I start my X it comes on normally and other times it puts out no sounds. Like the display is working just fine and i can turn the volume up and down and see the bars move across the display like the volume is changing but there's no actual volume from the speakers. Sometimes I never get output from the speakers for my entire 30 minute drive and other times it may just instantly without warning start playing over the speakers.
When it's not working changing stations or changing to cd/dvd doesn't fix it. It's completely random? I've been searching the net for issues like this and I've found a Taurus forum and a poster had the same issue with his factory Taurus stereo. He replace the RCM, which I assume is a radio control module, and it fixed the issue. Does the excursion have an RCM?

My backup assist only works when it is raining!! I have read all the posts I could find on the back up system, but have not found one one my issue. I had my wife turn the key on, engine off and put the truck in reverse. I put my ear to each sensor and they are clicking. So I am assuming they are working right. I took the speaker out and cleaned it and put it back in. No beeping at all!!
It was raining really bad one day last week and as I was sitting at the curb in reverse waiting to back into the driveway a car passed me and the system started going off. It startled me and the kids. I backed in and it worked as it should. Later that night we went out to eat and it was still raining and the system worked as I backed into a spot near a light post.
The rain stopped and the truck dried out and now the back up assist is nonoperational again! What is going on? To me it seems the moisture is completing a circuit that is not being completed when dry!

Looking at another Ex but the owner says the transfer case does not engage. Says it can be locked into 4X4 by crawling under it and engaging it manually by removing a motor [Servo motor ?] Does this mean I would need a new transfer case or just the servo motor ? I know mine did the same thing last winter. It would go into 4X4 and then pop out.

I had to make a few trips up and down the snow covered driveway. I moved the dash switch to 4wd high for each trip and then back to 2wd when I was turning around at each end. On my final trip back, I got stuck while turning around in 2wd. I tried switching to 4wd high and low but could not get either to engage with rocking back and forth.
The dash light did not come on and only the rear right wheel was spinning. Shifting to park or neutral and turning the switch to 4wd did not change the results. When I finally got myself unstuck, the 4wd still wouldn't engage when driving in a straight line.
What could have broke or stopped working? Bad vacuum line? Bad fuse? Could I have still initiated 4wd by manually locking the hubs? If so, is the process with the dash switch still the same even when manually locking the hubs?

I have a 2005 Excursion with 6.0 PSD just turned 80,000 miles. About a year ago, the vacuum hubs on the ESOF system became intermittent, so I changed then out with WARN manual hubs, which proved to be 100% reliable. Today, I got in the truck to move it, and engaged 4x4 High, as it had snowed last night and my inclined driveway was slippery. The hubs are locked, I get a lighted "4x4" idiot light on the dash, but the front wheels are not providing any drive power at all. I can hear the transfer case shift motor moving the gears, and if I select Low Range, the transfer case does change over to Low, but still no drive coming from the front wheels. I'm under the impression that the only things left to fail would be for the propeller shaft to be lying on the ground (it's not), the differential is not working, or something is wrong with the spindle shafts. Nothing has happened to the truck, and I have not heard any strange noises. I parked it 3 days ago, and everything, including four wheel drive, worked fine at that time. What may be going on here?

I have the ESOF in a 2000 Excursion. I went to use 4X4 high and it would not give me 4 wheel drive. light on dash said 4X4 but no 4 wheel drive. I was in snow and only rear wheels spun. When switch is placed in 4X4 low I get 4 wheel drive.

I just picked up an 05 6.0 Limited and love it, but I can't figure out the overhead temperature gauge. It shows -40 degrees no matter what, but if I hit the outside temp button on the climate control, it shows the (mostly) correct temp. I verified that the temp sensor in front of the radiator is still there and hooked up, and it seems to me that Ford wouldn't go to the expense of using separate sensors for each readout, so I'm guessing that the problem is in the overhead unit itself. All of the other functions (compass, mileage, range) work just fine. I've seen several threads about the overhead dying completely as chips rattle loose. Is it also common for just specific functions to go out as things start to shake apart?

Okay, So my rear washer is not pushing out the nozzle. Pump works, line from res checks okay, nothing frozen at this point. What route the line goes through the body, or what the diag steps are or the process to service it?

Fairly new to the ex. I just picked her up from the stealership last night, I'm in love! It's an 05 limited, v10, 71k. Loaded. Still tryin to figure out all the bells and whistles. It has one issue, I think it's minor, the drivers side power seat works intermittently, heat and movement. Being an electrician I believe it's probably a bad connection.

Just a little background, my Ex is a 2000 V10 4x4 with 217,000 miles. I've owned it for a little under a year. Very clean truck, and well maintained by previous owner. Now the issue. Starting about a month after I bought it, it would occasionally hesitate to engage drive from park. I checked fluid and it was full and clean. I had a buddy recommended that I check for chafed wires in the steering column which I did and found nothing. It seemed to get better for a while but now it's back. It's doing it more than half the time I put it in drive and sometimes takes 10-15 seconds to engage. So am I probably looking at a new trans? Or, is there anything that can be done to save the old trans?
