4x4 lights not on. Service 4x4 light is on.

I just got myself a blazer that Ive been working on, so one of the problems that came up was that non of the lights on the 4x4 dash module work. Also a service 4x4 light came on the dash. I click on the buttons nothing happens. I do have my abs light on, not sure if that does anything. Anyways anything would help! 99 blazer LT.

Search for threads on diagnosing and replacing the Transfer Case Control Module (TCCM). On a 99, like many, they can go bad but are easy to access under the passenger kick panel.

If what was already suggested and failed try replacing your 4x4 push button switch on your dash. I have the same problem with my 98 Blazer, keeps blowing the #15 10amp fuse.
