this seems to be because either the connection to the solenoid is loose or faulty or the solenoid is not activating. the transmission control module sends a signal to the solenoid to activate it. you get the light because the ecm detected that there is a a problem with the circuit. this is due to the fact that there is a voltage value to the solenoid and it is out of operating parameters

Just to clarify, the "transmission" is not stuck in 4-Lo. It is the "transfer case" that is attached to the transmission that actually engages the 4-Hi and 4-Lo modes. To properly shift your vehicle into 4-Lo, you know that you have to shift the transmission into neutral and slow down to less than 5 mph. Once your vehicle slows down to this range, your can switch your transfer case into 4-Lo mode. Due to the inner workings of the transfer case, the actual shift into 4-Lo may take a few seconds to complete. This is normal and does not signify that there is an issue. All transfer cases that have 4-Lo mode will act this way regardless of the make or model. To make a long story short, to shift out of 4-Lo you must follow the same steps that you took to shift into 4-Lo, just in reverse order. Switch the transfer case to 4-Lo mode if it isn't already there. Slow down to less than 5 mph (your vehicle must be moving, though). Then, shift your car into 4-Hi or 2WD. Give your vehicle several seconds to complete the shift. The transfer case indicator light will flash until it is complete. When it does complete the shift into the new gear mode, you will most likely hear a "clunk" (the range sleeve inside the transfer case disengages from its mating spline) from under your car. Again, any transfer case with 4-Lo (regardless of make or model) will exhibit this same noise. This should help you get out of 4-Lo. It is good practice to shift your car into and out of 4-Lo at least a few times each year to keep all of the splines free of corrosion and build-up. Based on the age of your vehicle, your transfer case may also need a complete flush and some new transmission fluid. Hope this helps.

The first thing I would look at is the shift rod on the transfer case. If I remember correctly, it is on the drivers side and is a rod aboutsix inches long and has two ends that basically pop into rubber gromets. If that rod is bent in any way, or has come loose of the gromets, it will not shift into or out of the four wheel drive. If yours has electronic four wheel drive, the electric acutator could be out or going out. you should be able to remove the rod and simply move the switch by hand on the transfer case. It will get you out of 4 wheel drive until you have the ime to diagnose the electronics at least. It has happened to both my 1994 and 1999 S-10 blazers.

I have a 19934x4 bought it with 4 wheel drive notworking. indicator lights for 4x4 would notlight up but transfer seemed to be shiftin ok. frontaxel woul ot ingauge. I repled the front axel actuator an works fine now no problem. actuator is on the passenger sid back of the front axel pigand has a plug, mine was 2 wireroundpin plug but some have a flat pin 4 wire plug. 70 dollars at NAPA. wasa realy simple replacement didnt even need to jack up the truck. the actuator h a pin that electronically puses out engauging te front axel. a easy test is to put the truck in 4 wheel high. holdthe brak and givei little gas ad havesomeoneelse stand to the side ofthe front of the truck and see if the front axel spins. ifso th actutor is te most likely prblem. hope this helps.
