Re: How do i reset service 4x4 light on a chevy blazer...
You don't reset the light it means their is an electronic problem with the 4wd system, which will need to be diagnosed at a dealer or experienced mechanic shop

5 year difference,i would not take that chance, the pcm not programmed to that transmission older transmission going have differet set up,the electronics will not match up.you will have check engine light problems and shifting problems look for same year transmission your vechicle has.
Turn on ignition switch and system should chk itself. If all is right the light should drop out..You may have to drive it for the sensors to register presence.
my 2000 chevy blazer zr2 4x4 the a/c switch that does 123 and 4,the a/c only works on num 3 setting.ive just replaced the whole a/c sytem and blower relay.it wont work on num 4 at all and when it does it cuts off on its own and then works on setting 3 only?what to do?
From someone that has had a 2000 Blazer for 6 years now I would say return the vehicle if you can and run the other way. Blazers are VERY poor in consumer reports and I average spending almost 1000 every 2-3 months. Oil cooler lines leaking, Idler Arm, Ball Joints and Bearings (felt like I was on ice in summer), Fuel pump. What a headache. I will never buy another GM.
