My service 4 wheel light comes on and then shuts off its a push button 4 wheel drive system so when I switch it into auto 4 it switches to 4 low when I try to switch it back to 2 wheel drive then put it back in auto 4 it will switch to 4 low or high I try to have a code run but no code shows up I've switched out both front hubs the only thing I can think is that it's the front actuator or there's a problem in the transfer case I need help please and thanks chevy chick

I have recently had this problem with a customer. It seems the 4x4 low will only engage in neutral with the brake applied. And also check fuse. Then select drive and you will feel it lock in. Don't "goose" the fuel when attempting this.

Hi my name is Juan and I do own a trailblazer with the same year 2002 and I read the problem you have let me try to help you Have you try to shift to 4hi with your transmission in neutral ? the transmission needs to be in neutral in order to shift the transfer case to 4hi and the vehicle needs to be completely stooped also is your service 4wd light on?? if the light is on your transfer case needs service and it can be as simple as the switch inside your car or a solenoid that has not been detected by the computer

sound like problems in transfer case shift module.

a couple questions is it the motor on the transfer case ( encoder motor ) or the motor on the front diff.? that you are having all the problems with.
