97 F150 4x4 Problem

01 ford f150 4x4 not working

If it turns it is a problem with the transfer case. Lift and support the front of the truck so the front wheels are off the ground take safety precautions, chock wheels, jack stands, etc Key on, engage 4x4 and try to turn the front drive shaft. I had no way of knowing you'd know what you're talking about. It has lot of rust under neath. One, you could apply 12 volts to this wire with a jumper wire. Has anybody had this problem yet????????? Figuring that they were all related I decided to test the easiest system to access, the power windows.

Rule out transfer case problems: This is easy - get someone to put your truck in 4X4 and roll forward while you peek underneath from the side. Have you removed the shift motor and seen if it moves when switched? And I'd love to offer the same to you here as well. Posted on Nov 12, 2010 Lift and support the front of the truck so the front wheels are off the ground take safety precautions, chock wheels, jack stands, etc Key on, engage 4x4 and try to turn the front drive shaft. Have checked fuses vaccum and electrical connections right front firewall , kinda lost at this point, wonder if the 4wd switch on dash could be faulty. You have a Decent description, but a little more detail might help me, or someone else to know where to start! Let me know what you find. I replaced it and all is well.

F150 4x4 is not working

01 ford f150 4x4 not working

From what I have read, a good indication of a problem here is the absence of the dash light. I've had a problem with the 4x4 on my 97 f150 for some time now. Ford has been having chronic problems with water entry into these solenoids, corroding them from the inside and seizing them,as you've seen! Yes the the system is supposed to turn off after about ten minutes of turning the ignition off regardless of whether a door is opened or not. I assmed I had a bad relay because when switching, I did not hear relays trip. Ask for a part number for it and they will generally help out. Check the functioning of the solenoids: this is easy as well. I actually switched the pink and blue hoses around on it to see if it would make it disengage, and it did! Follow the lines down as best as you can, checking for spots with wear or rubbing.

When I did this, I engaged the 4X by pushing the shaft in but it was very stiff and hand to pull it out again with leverage from a screwdriver. I might be totally wrong. A couple of times while going around a corner I heard something pop once but still nothing engaging. Have you removed the shift motor and seen if it moves when switched? Engage 4x4 and probe the red ground wire to the engage solenoid closest solenoid to the fender. If it doesn't it is a front axle engagement problem. Presently, the front differential won't disengage at all when shifted into 2 wheel high and the 4x4 light is always on.

How to Tell If the Brake Booster on a Ford F150 Is Bad?

01 ford f150 4x4 not working

Hello It seems as if I have the same type of problem. When shifted back to 2 wheel, the shaft should slide out of the diaphragm towards the drivers side. I have a 1999 ford f250. Ok well maybe I fixed some of the problem but not all of it. One hose leaves from each solenoid at the front close side to the battery and one is pink and the other is blue greenish if older. It should have 12V all the time on it, and if not, it may need replacing. Another important note is that I asked the customer about water leaks on this side of the truck and also closely inspected everything as I disassembled looking for signs of water intrusion.

The models included a standard cab, extended cab, or crew cab and came with either a short or long bed. Follow the lines down as best as you can, checking for spots with wear or rubbing. Crawl under your truck, take off the cover for the actuator and watch as your friend shifts from 4X4 and back. It is a common problem apparently for these years of trucks to get water in the solenoids which then freezes and cracks them. The vacuum should alternate hoses when shifted and the pressure should be equal although it is surprisingly not a strong pull.

2001 Ford F150 4x4 Working: When I Turn the Selector Switch to 4x4...

01 ford f150 4x4 not working

I do not know where or what he is talking about. I drove around and shifted in and out of 4wd with no problems whatsoever. Of course, there's also the possibility the module went stupid on you and doesn't recognize wrong when it sees it. I let the truck cool down and all was normal again. Depress and release the brake pedal several times and pay attention to pedal travel as you step on it.

SOLVED: 2001 ford f150 supercrew 4x4......4 wheel drive

01 ford f150 4x4 not working

If it doesn't it is a front axle engagement problem. Do you have any part numbers and a name for that sensor in the transfer case? Since this web site will have access to many different vehicles I hope you do not feel like I am lazy by just passing along the web site instead of giving you the exact information you asked for. I expect it's probably a swich because you didn't mention a four wheel drive light flashing, which would be an indication of a module or output fault. A rebuilt transmission will not. If the module sees something that doesn't make sense, it sets the light, and if the switch is bad, it just assumes you've never tried to command four wheel drive.

If they click - they are working! I appreciate your information and I will post what I find out as I go. I'll report back with my findings. It is recommended that the fluid be changed every 30,000 miles. If your hoses look good and suck like I said, they should be all good this also confirms that your solenoids, and vacuum reservoir are working as well. They are a in the rare event you may need to contact them.

2001 Ford F150 4WD Will Not Engage: I Just Bought My Truck From Up...

01 ford f150 4x4 not working

If it doesn't it is a front axle engagement problem. If the truck has auto 4wd, it will be electric. Any help would be great since it is supposed to snow again in 3 days. The only way we can get it to come out of low is to disconnect the battery cable, Let it sit over night, Turn the switch off, Then reconnect the battery, It came out. Mine was just stiff and needed lubrication - which worked! When I did this, I engaged the 4X by pushing the shaft in but it was very stiff and hand to pull it out again with leverage from a screwdriver. You can get fancy and test them electrically they should each have 12V power all of the time but the easiest way is to put your fingers on the plastic caps and feel and listen for a click as someone shifts your truck in and out of 4X4.
