Hello new blazer owner/forumer, and i have a question about my 4wd system. I recently bought a 97 blazer ZR2 2Dr with 4wd and my lights for the 4wd system are never lit and when i hit the button to switch from to 2hi to 4hi the light will blink then i hear a loud clicking sound, and sometimes it doesnt even light or anythin when i hit the buttons. would this be a switch/electrical problem or something more involved?

 

What 4wd system do you have? Do you have a 4-button switch with auto4wd or the 3-button switch?

 

i have a 97 blazer with the 3 button 4wd system, 2hi, 4hi, and 4lo options!

 

any ideas on how to fix issue?
