Having problems with your Chevrolet Blazer ?
Hi i have a 2000 Chev Blazer, the service 4WD light appears now and then , we never use 4WD so was not worried about it until today i tryed to put into 4WD and it would not work the lights on the buttons would flash then not do anything the only button that would work was 2 Hi,
Will the computer in the truck maybe stopping it from working because it needs a service?
Thanks for your time
One of my vehicles is actually a 2000 blazer and i had that same problem believe it or not. you should check all the connections to the brain of the 4wd. take off the passenger side right side kick panel. the kick pannel is that piece on the side right there next to the door. take that off and you will see a grey box. pull the wires out and look at the ends. i cleaned mine out with a q tip because there was crud in one of them which screws things up. if that doesnt fix it you may need a new one. they can be really expensive from a dealer so i went to a wrecking yard and pulled one out of another blazer and it only cost $20. it works fine now :) i hope that helps.
