It might be that driver side control unit. They've been reported to have problems with short circuits (even mine has had problems) Check fuses. However, a junkyard is probably the only hope for finding those relays -GM generally doesn't make them anymore.

If its not engaging into 4 WD the vaccum actulator is more than likely stuck. The actulator is located on the front of the axle next to the the front gear hub it will have a plastic cover over it. Unbolt the two 10mm bolts that hold the cover on and spray down with WD-40, also pull back the rubber cover thats on the actulator staff and spray it. You might have to hit the staff a few times to get it to move just make sure its in 4WD. I had the same problem, that part is exposed to alot of water, snow, salt and so on. Or you could just replace it but its cheaper to spray it down with WD-40

If it is your transmission solenoids causing the problem -- your check engine light may not be on ... can you scan your transmission or (tcm) there could to a hidden code-- if there is clear the code and drive again if not .. here is the next step to diagnosing this ... on your valve body there is a transmission fluid temp sensor or (transmission range pressure switch assy). first unplug your transmission (round plug) look at the pins sticking up from inside the transmission plug side< you will have to use a mirror and flash light.... make sure that there are no bent pins or pins that look shorter than the others.... if this is ok the next step is to remove the transmission pan and remove the (TFT) - this is the flat black module with a 4 or 5 wire plug on it..unfortunatly if you do not have a ohm meter this may be a problem ... if you have a ohm meter the test is (where the brown wire in the plug connects to the (TFT) test the resistance of that connector (not the wire but the pin coming out of the black module (determine which pin the brown wire connects to).. The resistance should read 3088 - 3942 ohms if it is lower than 3000 that is a defective part (replace it) -- if you do not a a ohms tester -- see if you can get a good used (TFT) from a transmission shop. remember this is the first test .. you may have to do more testing before this is solved. As a Transmission builder for years this is the first test I would do.. If there is a hidden code - and clearing the code allows the transmission to shift again (this will be a temperary thing).
