transfer case module was clicking, and service 4x4 was flashing. i cleaned all connections, the 20 prong one on the module was pretty green on three of the pins. it worked for awhile, then truck sat for 3 months, it started doing the same thing, so pulled the module and c;eaned connections again, it didn't seem to do anything to help, so went to the bone yard and picked up a used module, still nothing, i figured it was bad also. broke down and bought a new one, still nothing working, also low fuel light on, and battery light on. i checked all the fuses i could find, i was wondering if there is a fuse or relay i am missing.

 

What are you working on?

 

Replacing the transfer case module. It was acting up with service 4x4 light coming on on the dash, all the lights on the push button 4 wheel drive flashing, and module clicking. After installing new one i noticed that the battery light, and the low fuel light are on, and no lights at all on the 4x4 buttons, and it will not shift into any 4x4 gear. I'm really getting frustrated with it, I didn,t think the battery light, and fuel gauge were run the transfer case module, or I am having other issues also. Anybody ever have a problem like this?

 

forgot to add it is a 99 blazer with the trailblazer trim package.
