My 1997 GMC Sierra lights for 4hi and 4lo blink when i push the 4hi button and then goes back into 2hi. but when i push 4lo it locks in and works fine. I tried changing the 4wd motor on the transfer c


THE TRANSFER CASE MOTOR IS ONLY FOR 4WD LOW. That would have never been the problem as soon as you confirmed it shifted into 4wd Low. 2wd and 4 Hi work off of vacuum. You may have one or two issues. A vacuum leak up by the front axle that engages the 4wd HI or the sensors on the transfer case.

How do I use the 4 wheel drive on my GMC Yukon 2004. What dash button turns the 4 wheel drive on?


Hi, depending on the vehicle, there can be different controls. Standard control, 4hi, use in slippery conditions, never on dry pavement. Just push the button, and it will engage. 4low is for extreme conditons and the transmission must be in neuteral to engage 4lo. If you have auto 4wd button, just press the button in slippery conditions. If you have a denali, it is all wheel drive, and there are no buttons to push. So, depending on the model, there are multiple ways, but pushing the button engages it. Good luck...Goop

When 4hi or 4low is selected indicator blinks but system does not go into 4 wheel drive. When put in 4 wheel low rear locks engage.


Nine times out of ten its your push button switch module. fortunatly its not too expensive so if you are the 1 of the 10 that it dosent fix you wont have wasted alot of money. Had the exact same problem with my 2000 silverado also,,, fixed it with the new switch. Good luck!

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.

Chevrolet truck 4wd switch blinks


If they are blinking I believe it means that there are fault codes present in the pcm. You need to get the computer scaned to see if there are an codes present. If you live near an Autozone or Checker autoparts they can scan it for free.
