Capping off a light switch---Please Help!!!!

We had drywalled over a door leading to a bathroom from our bedroom, but the light switch is still there. There is also a light switch in the hall. When we removed the switch, we capped off the wires and now the switch in the hall doesn't work... what did I do wrong?

Start at the beginning. Tell us ALL the wires at each location and what you did.

(looking @ the switch)...there are two black wires on the right and one red on the left, with the ground below. What I did was capped each on separately and think that maybe the two blacks need to be capped together...

sounds like you had a three way switch setup. Put the switch back and just don't use. If you just left the wires in the wall then you must either put the switch and box back or find the other end of all the cables in that box and disconnect the power so those wires are dead.

If you can tell us all the wires in the disconnected box and the other switch box we should be able to help you disconnect the wiring properly. We might also need to know the wiring at the fixture, but let's start with the switches first.

Yes, two of the wires need to be connected together to allow the other end to work as a regular (single pole) switch. It's likely the red and one black, but there's no real standard. Try the red and one black, if it doesn't work, try another. There are only 3 options, two of them should work, and none of them will damage anything, it'll just force the switch to not work.

Remember, if you cap them as I mentioned, they will still be live and will not be able to be buried. You'll need to put a blank cover plate on the box to leave it accessible.

If there are only these 3 wires (and ground) coming into the box, you can likely cut the wires and push the wire out of the other box (either the other switch box or at the light fixture), thus totally disconnecting the wires and removing them from the box so they won't be accidentally used. Once you have done this, you can drywall right over the box. (but be careful to ensure you have the right wires before you go cutting them!)

Hope this helps!
