stuck in 4wd?

does it work in 4low

Yes it works great as long as i'm going forward.

Suspension problem
2000 Chevy Tahoe Four Wheel Drive Automatic 133000 miles

After getting a few inches of snow i put my tahoe in 4lo going uphill one night. Every since has been stuck. I've had the selector switch replaced, which after doing so the new switch won't read. No lights seem to flash or stay on. I've had the wires tested on the switch and they seem to be just fine. Could a bad accuator be the cause of the lack of power in the switch? I need help asap.

Have you checked to see if there is power to the actuator? If there is, that is the problem.

Vehicle stuck in 4 low tried the neutral thing and nothing. Has push button 4hi, 4 low, 2hi, auto 4wd. After trying a few times fuse for transfer case kept blowing. Finally got a fuse to work and still wont disengage. Took out front drive shaft to relieve some pressure due to the banging and wining in front and now its banging and wining back. What could be the problem here? The vehicle is stuck at our campground and we need to get it back here. Also the Service 4wd light is was not on until we disconnected the actuator. We did get it out of 4 low once anda few minutes later it popped back into 4 hi and then 4 low. HELP!!!!!!!!!!!!!!!!!!!!!!!

It sounds like the wireing for the actuator motor is shorting out some where. Follow the wires from the actuator motor back. It also could be the switch itself - try replacing it. 4L directly hooks up the rotation of the crank shaft to the rear and front differentials - with very little gear difference. Your differentials will explode if you drive it around in 4L for an extended period of time. The banging and whining in the differentials indicates serious issues internaly....keep me posted..

my 4x4 shifted to 4hi by itself then to 4 low and i cant get it out of 4 low. i changed the 4 wheel shifter switch in the dash, but no change. do you have any ideas what to try to get it back to 2 wheel drive?

get a helper to move the switch for you and go under the truck and see if it is sending power to the motor to switch it over. if it is then the motor may be bad or corroded and not working. if it's not then it could be a fuse relay or the switch itself.

Engaged the 4 wheel drive and when I was done, went to disengage it just like I normally do, but it is stuck in 4 wheel drive.

SYSTEM DIAGNOSTICS
The Transfer Case Control Module (TCCM) monitors transfer case operation along with input and output information. If TCCM self-diagnostic system senses a failure or problem in the transfer case control system, a Diagnostic Trouble Code (DTC) will be stored in TCCM memory. Diagnostic trouble code can be retrieved for diagnosis of transfer case control system.
DTC DEFINITIONS
DTC "1"
When ignition switch is in run position, TCCM tests whether RAM standby power (battery maintained power) to TCCM was lost since ignition was last turned off. When power is interrupted to TCCM (pin No. 6), TCCM stores loss of RAM standby power and sets DTC "1". If DTC "1" is present, check Orange wire circuit between TCCM and fuse block. Repair circuit as necessary. If Orange wire circuit is okay, replace TCCM.
DTC "2"
During electronic shifting, TCCM checks motor/encoder for normal operation. If motor/encoder does not function properly, TCCM stores motor/encoder failure DTC "2". If DTC "2" is present, check circuits between TCCM and motor/encoder. If circuits are okay, replace motor/encoder. If circuits are repaired, perform TRANSFER CASE FUNCTIONAL TEST.
DTC "3"
Each time electronic shift motor is turned on or off, TCCM tests whether motor functions properly. If motor does not function properly, TCCM stores motor link circuit failure DTC "3". Shift select buttons will blink to alert driver of problem. If DTC "3" is present, check circuits between TCCM and electric shift motor. If circuits are okay, replace electric shift motor. If circuits are repaired, perform TRANSFER CASE FUNCTIONAL TEST.
DTC "4"
Each time ignition is turned on, TCCM tests memory, program and internal system to ensure TCCM is operating properly. If fault is detected in TCCM, it stores a RAM/ROM memory failure DTC "4". If DTC "4" is present, replace TCCM.
RETRIEVING DTCS
NOTE:Diagnostic Trouble Codes (DTCs) are displayed on 3 transfer case shift select buttons. When proper conditions are met, select buttons will blink to indicate DTC from "1" to "4".

Turn ignition off for at least 6 seconds. Locate DLC near right side of steering column. Install jumper wire between diagnostic pigtail (Orange wire at DLC terminal No. 13) and ground.
Turn ignition to run position (engine off). Observe shift select buttons. If all shift select buttons blink once at same time then stop, no DTCs are stored. If only one code is stored in TCCM memory, that code will blink repeatedly, with a 3 second delay between sequences. If more than one code is present, next code will flash after a 3 second delay, then sequence will repeat. Count number of blinks for each code. See Fig. 1.
Write down all DTCs. After retrieving DTCs. Clear TCCM memory and repeat procedure. See CLEARING DIAGNOSTIC TROUBLE CODES. If DTCs return, perform appropriate test. See DTC DEFINITIONS under SELF-DIAGNOSTIC SYSTEM.

CLEARING DIAGNOSTIC TROUBLE CODES
NOTE:DTCs will not be cleared if 20-amp T-case fuse is not removed for at least 30 seconds.

Turn ignition off. Remove T-CASE (20-amp) fuse from fuse block. Wait at least 40 seconds and reinstall fuse. Cycle ignition on and off 5 times. All DTCs will be cleared from TCCM memory.
