2008 montana, how do u change headlamp light

Theer are 2 common stlyes of headlamp. If you pop the hood and look directly behind the bulb that is out (at the backside of your headlamp) there is going to be either a black round rubber ring that you need to pull off or a plastic rins that turns and pulls off. from there you will either see a little metal clip or nothing if you see nothing turn the bulb and pull out. If there is a metal retainer push that in and (up or down depending on the driver or pass side) that will swing out of the way and your bulb will now be free. DO NOT pull clip off simply push in towards the front of the car and then swing!) If you have the type that cannot be accessed through the backside of the assembly you may have to unscew a few retainers on the top side of the assembly then gently pull it out and get to the bulb that way. I can't be possitive if these are the only two ways to try it. If you post a pic of the back and top sides of the assembly it would be a little easier to help you out. Good lukc hope this help a little at least
