Ford F-150 - 1997-2003 :: 4wd Not Engaging / 2wd Solenoid Always Activated
Mar 2, 2013
Found out the hard way that the 4wd does not work on this new stupid truck. I've been troubleshooting the solenoids and confirmed that the 2wd solenoid gets grounded and will read ~12V when switched to 4wd; however, the 2wd solenoid always remains grounded and will always read 12V across the plug no matter if it's in 2wd,4hi,4lo. What would cause this? It seems that I would have vacuum going to the front differential from both the 2wd and 4wd solenoids at the same time, thus not allowing it to go into 4wd. BTW, this is on a '98, 4.6, turn dial 4wd

I have a '97 Explorer XLT with a 5.0L V8. Recently, I've developed a problem, in which it doesn't always start. Sometimes, when I turn the key, there is a very loud click (as if the solenoid is engaging), but there is no start. The battery is NEW, and confirmed good, and the terminal connections are tight. I have also replaced the solenoid, but the issue remains.
If I turn on the headlights, before trying to start it, the lights DO NOT dim when the key is turned...indicating NO draw, on the electrical system. I can try it several days a week, unsuccessfully. And then, one day, I can turn the key and it will start as if there was never a problem to begin with.
I have lost confidence in my favorite vehicle, as I am afraid to drive it if/when it does start, for fear of being stranded. I am thinking it may just have a bad armature, or windings in the starter, but if that doesn't correct it, I can't return the starter (as it is an electrical component).

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.

My truck has started fine every time I've turned the key except for last night after work. I got in had all the lights on the dash and dome lights. I turned the key and nothing. Not even a click. Hooked it up to a company truck and it fired right up and ran fine. Drove home shut off and then started it a little later and it started fine. Then this morning it wouldn't start. I hooked up the jump pack and still nothing. I drove my fusion to work and when I got home I went out and it fired right up like nothing happened. Does the work sometimes not work other times sound like the solenoid on the firewall? 2000 4x4 4.6 auto 253k miles

1997 f150 electronic 4wd not working, lights on dash not working(they light up on start up) replaced transfer case motor still not working, checked all fuses, Do not feel or hear clicks on vacuum solenoid, Top vacuum lines on both have vacuum. Where do I go from here? What do I check next....

Do I have to drop the valve body to get to the shift solenoid? Is there only one solenoid? Anything special or tricky I should know about?

I am having some weird issues with my 2000 F150. When I turn the key all the dash lights go out and no start. Ran 2 wires from the solenoid to a switch and it will eventually start. The starter will start real slow almost like the battery is almost dead and then speeds up more and more till it eventually starts. After it starts the theft light stays on the whole time. At this point I have no clue what is going on.

On my 97, just had a new engine installed. Suddenly the Lo presser AC switch died. Now the Start Solenoid (I think) just clicks sometimes. Is this Solenoid on the Firewall the Start Solenoid?

I have a 99 f150 and it won't shift out of park. The taillights work and I tried to turn the key forward and move shifter to neutral but it didn't work. Is it the switch on the brake pedal or the interlock solenoid by the shifter?

I am having a problem with my 1998 F150 4x4. The 4WD is not engaging. It is a manual shift. I have checked the transfer case by turning the drive shaft in 2WD it is free. When I shift into 4WD it is does not spin freely. So I believe that is OK. I have checked the vaccum diaphram. It will move the piston when I attach a hose and pull vacuum on the inboard hose barb. So I believe the diaphram it self is OK. I am not sure if the hoses and selenoids are OK. They look fine. However there is a constant vacuum on the inboard hose line (red/pink color) wether I am in 4WD or not. Is this OK? How can I check the selenoids. If all this is OK, the next thing I believ it could be is the shift fork in the differential. Is that a difficult job? Do you need to pull the whole axle out to replace it?

2012 Santa Fe all of a sudden won't engage starter. First thing in morning it usually cranks. But once I turn it off it won't crank again. When I turn the key I have full power so it's not the battery or terminals. There's no cracking or popping sound, just a whine like the starter's not engaging. Never had any problems with this car so far. I'm thinking maybe it's the starter solenoid.

Ok so I was looking at my blend door actuator motor to see if it was working. Just took off the bottom vent cover, turned key on and moved the air mixture to see if the motor worked. (it didn't) Then I went to start the truck and all I get is the solenoid on the firewall click each time I turn the key. I put a meter on the opposite side of solenoid and I see 12v across the solenoid. I can't image i did anything while playing around by the blend door actuator motor. I guess I'm looking for confirmation that the next logical step is starter and starter solenoid. Is there anything else I could be missing? is there anything else in that circuit between the solenoid on the firewall and the starter? I also cleaned the battery terminals and the terminals down on the starter solenoid. I also tapped the starter a bunch and put a charger on battery and tried jumping the truck too. Everything else works.

03 F150 2WD-I dropped tranny pan, changed filter, reassembled, put in 4 qts fluid. Checked dipstick, seemed to be overfilled, despite instructions to add 5 qts. Started truck, put it in reverse, went about 4 feet and then tranny wouldn't engage-ran it through all gears, just acts like in park or neutral. Over or Under filled???

I was out on the lake last night and after getting stuck in 6" of hard packed snow, I discovered that my 4WD is not engaging. When engaging 4WD, I do hear 2 clicks several seconds apart. I've checked the lines from the solenoids to the actuator and did not find any cracks. I have not checked the lines for vacuum yet but...
Last winter while engaging 4WD, I heard a load POP from the front end when I was turning the wheel and engaging 4WD. Ever since then, I haven't been sure if its been engaging but it was confirmed yesterday on the lake. Based on what I've read, I assume its either the actuator or the shift fork. Is it possible to remove the actuator and test it without disassembling the entire front end?
I went under the truck and had my wife engage and disengage the 4WD. The actuator was trying to move (maybe 1/16" inch) but the shift fork wasn't moving. Does this mean the shift fork is bad (frozen) or does this mean the actuator is bad (not enough power to move the fork)?

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.

I just got a 99 Ford f150 with the 4.6. I am having problems getting the four wheel drive to engage. I turn the on the dash and the lights come on for four high and for four low. I have a 00 four by four and it works fine, so I know how to work it. In the 99 I can hear the transfer case engaging and everything clicks just fine just like it's going into fourwheel drive, but the front end is not pulling. The front drive shaft is turning but still the front end is not engaged. What the problem may be?

I have a F150, 97, 4.6L. I changed my Suspension belt, and now my A/C compressor is not engaging. This has happened before, and when I took it to the shop, they called me and said the A/C works just fine. They did not tell me why the A/C stopped engaging or what they did. I tried to locate a relay fuse, but I can't find it.

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?
