#307 of 396 2000 silverado push button 4wd trouble
Sep 04, 2010 (9:57 am)
vehicle does not shift into 4wd in either auto 4 or 4h or 4lo. it does shift to low when 4 low button is pushed. switch panel lights appear the same as when system worked. occaisonaly when switched to 4wd it will blow atc 30 amp fuse and then no witch panel lights and service 4wd message of course. I removed front axle actuator and it appears to work fine.
any advise appreciated

Try new select switch( The push Buttons ), also the connecter at the front accuator will sometimes have a short in it.
Lots of luck
#309 of 396 03 sierra 4xd problem
Sep 04, 2010 (5:55 pm)
I have a 2003 sierra 2500. I reently shifted the truck to 4 hi ti pull a trailer out of a ditch. i didnt have enough power to pull it out so i shifted to 4lo and pulled it out fine. I noticed whe i got back on the level ground i tried to shift back into 2hi and nothing would happen i ended up having to remove the motor from the transfer case and shift it manually to get home. once i got it back to my garage i reinstalled the motor and now the lights on the selector switch will only come on for a few seconds when i start the truck snd then nothing at all. I have tried a nnother incoder motor that didnt work and i swaped my switch out to my brothers truck and they worked fine in his.does any one know what the problem could be

while driving it seems like the trans downshifts and upshifts fast,like a stumble but the engine stays steady according to rpm gauge.could the speed sensor be a problem,and is it on the end of the transfer case? some one told me the tps could be the problem?

#314 of 396 noisy in 4 high when turning
Oct 19, 2010 (1:14 pm)
Hi new to this forum.My question is I just bought a 2005 1500 sierra z-71 and when I put it 4hi an turn it makes some bad sounds. Going straight sounds ok.Took it back the dealer and he said it was a normal sound when you turn in 4 wheel(something about the clutches coming in and out.)drive.The mech. said he went and drove two trucks the same as mine on the lot and they both made the same noise. I have a 2000 chev blazer zr2 and it does not make that noise in 4 hi but they said it is a differant drive system.Does that sound about right or should I take it some other dealer.

Having a problem with power to front axles in 4wd. I put on stands and put in 4wd and all wheel spin. If i hold brakes, the front dont spin. The front driveshaft doesn't spin at all either while there is a load on it. The front axle does engage though. In neutral with 4wd on, the front axle, driveshaft and everything move.
Now it does go into 4wd low, but still having problems with the power going to front shaft. Again up on stands, all wheels spin great. But i hold brakes and only rear spin. Could this be an actuator problem on transfer case? Bad fluid? Vaccum line? Or is the case just bad?
All 4wd selections including auto 4wd have same symptoms. But drive shaft does jerk like it wants to spin, just not enough power. 2WD works great, and no funny sounds, smells, or clanking in any selection.
