HELP - Installing Light Switch Dimmers BUT there is no green or Copper Wire The house is built in 2015 and I know it was supposed built to code to have it grounded. BUT after removing the switches, there are no green or copper wire in box. Box is metal and has GR on it. Reading instructions, I need to connect the green wire to ground wire. What if there is no wire to attach ground? I check other switches and NONE of them have the green wire in it attached to light switch. If the metal box is grounded, how can I tell using a multi meter? I have heard you touch the black to metal and touch the live wire which is hot to see if there is current. There are two red wires that look like diagram that have the wire going from top and bottom loop together and it reads a voltage 115v, but looking further it is the secondary live wire. Can anyone give me advice or should I contact the company who built the house telling them their contractors did not ground any outlets [img]https://cimg4.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/94305d5b_720d_4854_b485_c6204c326559_e887e1795c27ae6c9c3ad2d641f35efa994b73aa.jpeg[/img] [i]This is the instructions for the light switch.[/i] [img]https://cimg5.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x2000/8c26b792_ba48_4dfa_b22a_571f327b2b1f_ff1932f579ec3da9cdbb6e6f2b9a17d457f5c0df.jpeg[/img] [i]This is how the current light switch is hooked up.

I just changed the fixture about the bathroom mirror. I have 2 blacks, 2 whites, a yellow, a blue and 1 green. I did everything perfect but now my light stays on even when I switch it off. I have rearranged the yellow and blue multiple times and can’t figure what the problem is. I did nothing with the switch. please help
