I have no fog light on my HHR, just black covers and was wondering if there's already wires for these somewhere and a button if i want to install some ? Thanks

 

The answer is .....Maybe.

Is the relay and fuse installed? Then, probably.

Are the wires for the switch behind the waterfal? Then, probably.

Some have it some don't. doesn't seem to be any reasoning.

BTW, you are not the first to ask the question. There is a how-to on after market as well as prewired. Give search a shot, or scroll through the how-to area.

 

If the wires are there you'll need the dealership to advise the BCM there are now fog lights!

 

BCM ? i did see some unconnected light wires attached to the frame.
thanks guys.

 

BCM (Body Control Module) has to be programmed to know the fog lights are hooked up. Since the BCM controls all the light functions, it has to know they're there to control them.
Control as in turn them off when you use high beam headlights. Or turn them off when you turn off the ignition. The fog lights don't come on when you start the car. They have to be manually turned on each start cycle.
