1999 Chevy Blazer 4wd not working.?
I have a 99 blazer, never had no problems with 4wd until now. Recently i hit button, and it feels like its engaging, but the back tires were spinning, and the front tires were doing nothing. Does anybody know what i should look for or where to start. Thanks in advance Mike

the 4x4 modulator in the front diferential. its about 500 bucks but you could do the job yourself if your not an airhead
Source(s): im a mechanic and thats the only reason ive seen that wont engage the 4x - Anonymous5 years ago
Put the car in park. Then switch the rear tires but dont put the lug nuts back on. Then take off the differential plate and turn it on. Drive it in a complete circle and if you dont hear a clicking then it's just the 4wd switch
