My truck seems to be stuck in four wheel drive even though my switch is in 2 wheel drive. When driving it sounds like it is stuck in. I have tried to stop and switch between all ranges in nuetral mand it does not work. Can someone help me out on where to start looking?
check the fuse. There are three main things that will blow the fuse; the front axle actuator, the encoder motor on the transfer case or a mechanical problem in the transfer case. First unplug the actuator and see if the fuse blows. If not the actuator is bad, If the fuse blows, unplug the motor on the transfer case. If the fuse does not blow with the motor unplugged, but does with it connected, remove the motor from the case and try again. If it still blows the fuse, the motor is likely bad. If the fuse does not blow with the motor out of the transfer case, the problem is more likely internal to the case. If it binds internally, the motor will pull too many amps and blow the fuse.

turn the vehicle on and have 2wd selected and get under the truck and tap on the shift motor on the transfer case with a small hammer or something see if it will pop out. ive seen alot of motors go bad and if you hit them they will go to working again, for a little while anyways. it could be a control issue or internal transfer case issue. but hitting the motor is best thing to start with.
And ditto on kbro's post. Makes sense to me
I need help. My truck is stuck in 4 wheel drive low. The switch just blinks then go's out.
It's the motor my dads truck did this and I changed the motor and it works flawlessly now
Put your transmission in neutral first and then shift to 2 wheel drive. It should shift out of low right away
I had my 4wd suddenly go out on my 94 Silverado. I researched and believed it to be the Actuator. I replaced with new one and still no 4wd. Then I checked the fuse(should have done that first) and it was blown. I replaced the fuse (25A) and the 4wd worked. I was going to take back the Actuator I bought, but figured with 202,000 miles, $87 was worth replacing it. I am assuming the blown fuse was result of bad Actuator. So, if your fuses keep blowing, replace the Actuator too. Hope my experience helps.
I put into neutral and the pressed the 2wd and it switched.
I just purchased a clean 2001 Silverado 1500 HD 4wd, it test drove pretty good and after a full tune up and final test drive I lost all gears at a stop sign. No noise or vibration, I got to the stop sign and nothing when I tried to accel. No gears at all, there is a spinning/grinding sound below. I towed it to the local mechanic and he said he didn't think it was the tranny or transfer case but rather the shift motor. I called another tranny mechanic and he suggested the same. Any thoughts or relative situations, parts about 150 and labor is about 50 they say but im curious is there a way to test or work around? N.
