Hello, put your transmission in neutral before you shift to 2hi. If it doesn't shift put it in reverse and back up a few feet.

How do I fix my 99 blazer the dome lights won't turn on and the 4 who drive won't light up or work


In the instrument panel fuse box fuse # 8 CTSY LP 10A ,that's for the dome lights, fuse panel is left side of IP. What are you talking about 4 who drive won't light up or work ? 4 wheel drive ? Do you have two speed automatic or two speed selectable ?
Switch Indicator Lamps Do Not Light - One or More ? Check fuse #15 IP fuse box 10A 4WD . This is for two speed auto !

Circuit Description

The indicator lamps circuits consist of 5 individual lamps contained inside the mode/range switch assembly, they are AUTO, 4WD, 2HI, 4HI, 4LO and NEUTRAL. The AUTO, 4WD, 2HI, 4HI, and 4LO lamps are contained inside their respective range button. When the ignition is ON, the transfer case shift control module illuminates the indicator lamp that corresponds to the current ATC gear position by providing a ground through a current limiting driver.
The transfer case shift control module flashes each indicator lamp after a shift has been requested and will continue to flash until the transfer case shift control module can complete the shift. After a shift to AUTO, 4WD, 2HI, 4HI, or 4LO is made, the transfer case shift control module will flash that indicator lamp until the transfer case shift control module receives a high voltage signal on CKT 1695 from the front axle switch.
A solid state circuit located inside the switch supplies ignition voltage to the lamps. The solid state circuit also receives voltage whenever the headlamp switch is in park or headlamp position. When the solid state circuit receives voltage from the headlamp switch it will reduce the voltage that it supplies to the indicator lamps, dimming the lamps when the headlamps are ON.

2000 chevy suburban stuck in 4 lo anyone out that cant help


Put truck in Neutral while key in run position engine off or on (doesn't matter which). If it's pushbutton 4wd then try hitting 4low again. if that doesn't work some of the chevy trucks required you to press 4hi to get into 4high and then press 4hi again to get back to 2hi, unless yours has a 2hi button. In that case press 4hi to get into 4high and then press 2hi to get back to 2wd. either way you need to be in neutral to get out of 4lo. I have shift on the fly (Mechanical Shifter on floorboard for transfer case) on my 1990 Suburban and still have to put it in neutral to get out of 4lo. Good Luck.

Shifting 4x4 4lo


Most likely cause is the encoder motor on the transfer case.

I have a 2001 GMC Sierra Pickup that has electronic 4WD that will not engage. If you press the buttons to enter from 2HI to 4HI, 4LO, Etc. the choice of the button changes (lights up) but the truck does...


fullyjr.

Engaging from 2WD - 4HI/Lo requires movement of the vehicle. very low speed under 5mph, push button should engage. the vehicle has to be moving.

02 dakota wont shift from 4hi to 2 hi


Try commanding the drive ranges while in netural cycling them. This may normalize the controller that senses the position from the encoder motor assembly. There maybe a procedure for that in a service manual.
