4 wheel drive wont engage

4 wheel drive wont engage

Postby Metaldog [OP] » Oct 26 2012, 3:17am

I've replaced two electronic items, the switch on top of the transfer case and the control module on the front axel. The two wheel drive button on the dash is lit, and when I hit the four wheel drive button it flashes 3 times then clicks back to 2 wheel drive. The small electrical motor by the transfer case appears to be functioning. Any tips or any further questions, I would really appreaciate your help.
Thanks

Having a similar issue myself with my 96 chev 1500 that I'm wanting to sell, except the 4-hi light will continue blinking. After a while it will let you switch into 4-lo but still wont lock in the front end.

I tested most of everything seams the transfer case module isn't working. I will replace next week and let you all know if that fixes the problem.

I originally thought it was my front actuator also because when I looked underneath it was broke off inside the housing...go figure it was plastic and something had popped up and broke it. (No skid plate) I couldn't get it out so I had to take to the dealer they got it our for me. When I got it back still just flashing when I put it in 4wd so next thing would be the brain. Should have it done on Tuesday. I looked at it yesterday takes about 30 seconds to remove the module under the drive side dash... will post once I have replaced it to let everyone know if it fixes the problem,
