I've done a bunch of searching and came up with some questionable results that generally end with someone shifting into N to fix their problem.
I have an '02 that won't go into 4lo. It goes into 4h, and the 4wd clearly works, but when I hit the 4lo button, the button flashes maybe 10 times and then nothing happens. No low range, and no light on the dash (I assume there's a light on the dash that should come on). I've got it in neutral, foot on the brake. For what it's worth, it's a manual trans.
I pulled the transfer case actuator for no particular reason, just to check the wires and connections, and everything looked clean and solid. Beyond that, I'm kind of lost. So here's my questions....
Can I assume that the actuator is good if it goes into 4h? I would think if the actuator is bad, it wouldn't do anything.
I've seen posts about the 4wd control module. That's the module behind the glove box, right? I poked around with that about a year ago and tried to swap in one from an automatic. All the warning lights on the dash lit up and my speedo didn't work. Clearly they don't swap. Is there a way to test it? The module for the manual is no longer available. How often do these really go bad compared to other causes?
The manual says if the 4lo switch is flashing, that means the vehicle is waiting for driver input, like shifting into neutral. Previous owner told me he put a clutch in it. I'm thinking maybe the sensor that detects if it's in neutral may be damaged or something, but if that were the case wouldn't that affect starting somehow? The truck won't start in gear, so I assume that switch is working.
I'm lost. Any thoughts on what I should check would be appreciated.
