The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

How do you clear codes on your 1995 Chevy blazer to get the 4x4 working again?
First uf all, The computer has nothing to do with the 4x4 on this year truck. If your check engine light is on , Then there's a problem in the system wiyh the engine or transmission, Not the 4x4. You need to check the 4x4 Actuator on the front housing to see if it has power going to it when you ingauge the 4x4. Check it with a test light. If it lights up the test light, Then replace the actuator in the housing. If it don't. Then go to the top of the Transfur case and you will see a switch on it. Check it with a test light, With the 4x4 ingaged, if its hot there then replace that switch. Before you do anything check the 4x4 Fuse's in the fuse box with a test light.
