Question about 2001 GMC Jimmy
When I turn the 4 wheel drive on in any of the areas other than 2 wheel drive the lights blink and I dont think it is going into 4 wheel drive.
Vacuum lines my friend. There is one under the battery that pulls a cable to lock the front differentials in. But also check to make sure each line is getting vacuum.

I have tried 4 wheel high both ways and low 4 wheel sitting still, I can hear what sounds like the rear gear box locking in low but I dont hear the front, and again the auto 4 wheel drive the 4 wheel high and 4 wheel low just blink.

Are you setting still or driving when ingaugeing the 4 wheel drive if you are setting still try putting it in with vehicle moving if it does not light up steady in 4wd then it is not going in 4wd
