Question about 1994 Chevrolet S-10 Blazer
How do you test the transfer case motor and the wiring on a 1994 s-10 tahoe edition blazer with push button 4x4. The blazer is an automatic transmission with the 4.3l vortec engine code "w".
I have a 1993 blazer 4.3 w code 4x4 with a 4L60 E . my truck wouldn;t go in 4 hi or low. so i changed the transfer case motor and it works fine now. If you turn the ignition key to on but not crank the engine and open the driver door and push 4 hi button, you should hear the transfer case motor cycle for 3 or 4 seconds every time you push button and the light will flash until it goes in 4wd If the 4 hi button light doesn't flash during cycle then it could be a bad switch. if the transfer case motor won't cycle it could be a fuse or a bad transfer case motor . Hope this answers your question.

Replaced my actuator because the boot was torn which gave me 4wd again but was unable to shift back to 2wd now. Also disconnected the vaccum lines off of the transfer case but I'm not sure which one goes where?

Check the Actuator directly underneath the battery and battery tray.... if the rubber is torn there's your problem... I had the same problem 2 years ago
