Hi. on my buick the day time light don't work since I change my bulb
where is located the day time light module

I forgot to say that's a 1994 Regal grand sprot
thank you

Do you mean the fog lights? These are the two lights located in the front spoiler. Regals didn't come with daytime running lights until the next revision in late 1997. So on your car there is no daytime light module. There should be a fog lamp relay in the fuse box under the hood. It turns off the fog lamps when the high beams are switched on. If this relay is bad your fog lamps won't work at all.
