If the floor vents are still pushing air, look for broken/deteriorated vacuum hose at the firewall right behind the battery. You will probably have to remove the battery to see it.
I've experienced the same sort of vibrations at steady speeds of 45-50 mph. Not just a subtle vibration, but enough to make you think "what the hell". In my case it felt like the transmission was maybe going in and out of lock up mode quickly. It only happened a couple of times and that was a...
The reservoir on my '03 was all nasty like that about 10 years ago. Stuck the garden hose down in it and turned the water on full blast and just let it overflow until it cleared out all the whatever it was that was in there. Almost looked like algae. Have you been using just plain water in it?
Over the course of 30,000 miles from 60k to 90k, I had 3 coils go bad. After the 3rd one, I just went ahead and replaced all of them and the plugs too.
Must be a common problem on Expeditions. My rear washer line became disconnected behind the passenger side interior kick panel. Drained the entire gallon of fluid into the bottom of the door frame. This on an '03 Expedition. No wonder my rear washer hasn't worked in several years. I...
'03 Expedition. Removed the the wiper cowling and replaced some washer hose and a broken "Y" connector that was shooting washer fluid straight up instead of on to the windshield. Repainted the wiper arms matte black while I had them off.
I typically get between 15.4 and 16.4 in my '03 Eddie Bauer with 5.4L engine. About 50-50 city highway driving. Are you getting a CEL or SES light, whatever they call it these days? How many miles are on your Expedition? When was the last time the plugs and coils were changed? Have you had...
It's a shame you don't know the service history, especially on the transmission. But I would take a chance and change the ATF anyway. Oil, coolant, differential fluid change. Plugs and coils. (Use Ford coils and plugs) With new tires,you should be good to go.
Watched the video. Sure looks like it could be a plugged cat. If not, I would look at the fuel pump being bad. Didn't see a flashing CEL, so apparently no misfire. No CEL. That's strange. What's the red light at the bottom of the dash?
Any OBD codes showing? But it sounds like you may need a transmission overhaul. How many miles on the vehicle? Check the transmission fluid. Is it low? Is it dark or reddish color?
During the day I can just barely read the info on the Information center. That little LED read out that tells you MPG, door ajar, miles to empty, etc. It's really dim. When I turn the headlights on, it goes to night mode and gets even dimmer, but it's not a problem at night. I thought that...
At 5'9", I don't have a problem reaching the dipstick to check the oil. But when I wash the Expedition at home, I need a step ladder to do the roof. Hence, the roof doesn't get washed that often, lol. Well, no one can see it anyway, except for 18 wheeler drivers.
You might try this to eliminate the start up rattle. It works on my 03 after sitting for a week or so.
Hold the throttle all the way to the floor for about 3 to 5 seconds while cranking the motor. While still cranking, release the throttle. It won't start until you release the throttle. That...
@ OP. Yeah, it was just very low on refrigerant. I usually fill until the compressor stops short cycling like that. But without a gauge, you are still just guessing. You can buy a can of R134a that comes with a low pressure side gauge. That helps a lot to see where you are at and keep from...
