Blazer headlights and service light
So i have a 1997 white blazer lt. For some reason, my headlights never turn off and idk why. The green headlight light on my dash stays on, and it really bugs me... Also, my service engine light has been on for a while. The previous owners had their mechanic friend look at it and he got it off for about a day before it went back on. I think it may be because the gas cap doesnt click when it closes, but im not sure. Thoughts? Thanks

First, check what codes its throwing. As for the headlights, The green headlight on your dash, is supposed to be the indicator for the high beams, are the high beams stuck on?
When you say they are always on, what do you mean specifically. Like you cant shut them off no matter what?

What 4x4 said, sounds like daytime running lights.
Here is a quick test (as I always thought the headlight dummy light on the dash was for the high beams) is, when its dark, pull up against a building, and turn on your high beams... see if they come on, if they do, see if anything lights up on your dash.
If its the DRL's, there is a mod to fix this that involves adding a 2.2kohm resistor to the sensor that is located in one of the speaker grilles in the dashboard (I believe its a 2.2k ohm resistor. I will have to search in the morning)

That's correct - they don't.
If your 97 is a four door LT - which is exactly what mine is - then you probably have composite headlights. There'll be two bulbs in the housing, and this is what the majority of four door models had, from my understanding. A lower amount of power is sent to the high beam bulb, and it automatically cuts out when you switch on the headlights. It can be deleted, although I don't really see a purpose to it, and it can be done as simply as cutting the DRL wires to the high beam bulb ballasts and taping it off. Kind of a jury rigged way of doing it, but it's quick and simple. Or you can add the resistor, or you can go all out and remove the DRL panel completely, which is going to involve disassembling the dash.
