i have a 1994 s-10 blazer with 4.3 and has the push button 4lo and 4hi. when i try to engage the 4hi all i here is a click on the passanger side and the button light up but no 4hi. when i push it to go into 4lo i here the clicking noise and here it go into 4lo and the light stays on. i was wondering what may be the problem? i know that it use to work b/c iv had it in 4hi time b4. i think all that is worng is that the cylinder wont engage like a bad conection but i just would like to know wht other ppl think. so if any one could help me please reply?

Thanks
