Having problems with your GMC Sierra 1500 ?
My 1996 gmc 1500 4 wheel drive button only flash. you can hear that the transfer case shifting but nothing is locking
If you can hear the transfer case shift and lock in then you will need to check the acutlator at the front axle . this acutlator is screwed into the side of the front differnatil and recives a signal from the transfere case module to engage the front axles or lock the axles so they will turn . General motors has updated this part a few times .to make it work better . I dont know if this part can be found at a local parts store but it would be worth a try and check with them as the part is not cheap from the dealership
