4x4 Low won't disengage
F150 XLT 1997 4x4 Automatic. Major problem is that once into 4x4 Low it does not want to disengage back to normal 4x4 or 2wd. Tried when stopped in nuetral & also stopped and putting in Reverse & also putting in drive with no change or disengage. Finally it came out but not sure what did it after trying the same things over and over again. During this ordeal the indicator Light showed regular 4x4 when switched to regular 4x4 but truck was still in low 4x4 range.
Any ideas???
Thanks..

Those air lines that attach to the two solenoids on the firewall by the battery are prolly leaking enough to cause problems with engaging and disengagement - check all those lines - You should have one main one running down to the axle and a breather running up from the axle.
Check all these for leaks -

Beachwalker, if you have a manual shifter, check to make sure the linkage is not loose. If ESOF, you will have to check on the shift motor.

They control the actuator. I would say the front axle has plenty to do w/4LO. I seriously doubt any of the two that need help have a manual shifter
The T-Case motor is back on the transfer case , it has a blue housing - check your connections back there, follow the wires, check all connectors .
Then check you voltage to the motor per manual .
Test the switch voltage as well, in all positions..
A Haynes or Chiltons book will have these procedures, If you have trouble finding them, feel free to ask , me or someone else in the forum may have them handy..
Good Luck

Engagement comes from the transfer case - what gets engaged ? The front axle- The "4" in 4low means 4WD . 4WD includes the front axle..
So what are you saying , when you put the truck in 4 low , the front axle doesn't turn or engage? .. Your hilarious dude..
Like I said 4low has everything to do with the front axle - stupid argument..
Rant all you want - I'm done . Mann this trans forum really sucks most of the time..

They can also be engaged without the transfer case being in 4wd if there is a problem with the disengage solenoid or the tranfer case itself.
Do a search for the 97-03 and the front axle not engaging. There are a lot of them here.

If the actuator locks and doesn't disengage via bad solenoid , bad airline, your going to have problems disengaging the transfer case. It might not be able to let go of the front axle because of said actuator problem. I said this in the beginning first thing because it's the first thing I would check.
When it happened to me - the red and blue line leading to the different solenoids then to the axle were severed by the battery that came loose in 4wheel drive..It would not disengage until fixed. After the repair I heard it disengage right after I started my vehicle...
You said the the two have nothing to do with each other , that's just wrong and you should stop passing bad information...
