Ok heres my situation here i recently bought a 96 blazer LS 2 door so i could have a 4 wheel drive but now that its nearing winter the 4 wheel drive seems to be acting up for example: when u turn the wheel to far while its in 4 wheel drive it pops out of 4 wheel drive and even more recently it has stopped going into 4 wheel but u can hear the mechanism under the blazer moving when u press the button so it gives the illusoin of going into 4 wheel drive but when u take off only the back wheels spin and also the fuse blows every other time u try to put it in 4 wheel so idk if it is a combination of problems or just one really big problem any help or advice would be appritiated thanks.
