Question about 2000 GMC Jimmy

Open Question

2000 silverado continually shifts itself into 4lo. it still has all the factory hardware and the switch lights all work. I can fool with backing/ pulling the fuse and such and it will go back into 2hi. but as soon as i stop the 4lo light starts blinking and it shifts itself when i stop. HELP Please!

You need to see if the transfer case engagement motor is defective.

vacuum leak or vacuum locker solenoid problem. a great way to check for both is to remove both vacuum lines from the solenoid (located on firewall above destributor), and put a connector between them, push the button on the dash and see if it locks in.

SOURCE: 4wd

I dont know how familar you are with 4wd but have you tried to put it in 2wh and put the truck in reverse for about 15 to 25 feet?Try that and let me know what happens and sounds you hear.Ill also need to know if you have push button or on the floor.

SOURCE: My 4wd switch worked fine. Right now it is stuck

I'm not a mechanic, but I recommend getting this in for fixing ASAP... Mine started doing the same thing, except going from 2wd to A4wd... now it is all over the place, I've spent $2000, and I'm still at square one... You don't want to wind up wrecking your transfer case (or the motor on it), as that gets costly!! :) Good luck

Dave,
The problem your are speaking about could be a few things. All things that are somewhat common to go bad on Chevys/GMCs. Each one of the cars I worked on had a different problem. I have changed the switches, the 4wd solenoid, and TCM on different trucks. IMO the TCM location in the passenger kick panel is a poor location allowing water and other passenger debris to get into it. Once water gets in that area you can imagine already what occurs. One of the cars the TCM bracket was rusted by the ground and eventually the weak ground fried it. The weird thing is the TCM would allow it to shift sometimes and not other times or partially engaging causing the wonderful light to blink rapidly. What I have found of some time with these trucks is pushing the button to change the truck to two wheel drive and driving a few feet in reverse helps ease the change.

So you can start with a new switch that pops in and out of the dash in a few mins. Can get one on ebay for under 25 dollars. Although, I personally would take off the kick panel and take a look at the TCM. If you see any rust around it, my money would be on that.

Good luck

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.

Shifting 4x4 4lo


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

2000 GMC Jimmy 4x4 Switch not working and Shifting hard between 1st and 2nd


Change the switch itself if it drives normal then randomally kicks into 4 lo/4 hi i had the same problem and a transmission shop told me it was the vaccum and the transfer case but one of my mechanic friends told me that it was my switch and shops only tell you other things for the money. Try changing the switch.

WONT SHIFT INTO 4HI BUT WILL SHIFT INTO 4LOW


Are you sure that the actuator on the front differential is actually engaging? On my 99 silverado, the truck acts as if it is in 4lo when the button is pushed but the front wheels don't actually spin. Get on the ground and listen to whether or not the actuator engages.You should be able to hear it hum. If it doesn't then i would say it is the actuator which is common. Good Luck!

Vehicle: 2005 Chevy Silverado 2500HD 4X4 Duramax. Problem, when I trying switching the 4 wheel drive switch to 4LO, the light just blinks continuously.


You should have it put on diagnostic scanner to tell for sure. system needs to be tested. As a mechanic myself, I know these can be done fairlty easy on most vehicles but some can be slightly tricky
