4wd is stuck in 4lo. Cannot get it to switch back to 2wd or 4hi. Would like to disengage 4wd all together if possible, but need to get it back in 2wd as soon as possible so I can drive.

Hello.

There is an encoder that goes out not being able to switch the car out of 4WD. Here is the location of the unit so you can check it out.

Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.

Cheers
