Cigarette lighter and a/c adapter do not work. Is there a fuse? If so where?

Possibly but more likely you've disturbed the wiring and it is now causing a short circuit

The lighter socket or the element.
Check the element for burn marks and the socket for debris blocking the contacts.

Here's a link to your fuses. Toyota Camry Fuse Box Location and Diagram

check all the fuses underneath on the left side of your brake pedal but there should be a box that has a black cover to it and underneath this might show the fuses. Check also in the engine fuses to see if any are bad also.

First check the fuse for your lighter. It will show you the location of your fuse box and lighter fuse in your cars owners manual.

I always use a test light and check them all. Usly faster then looking up which fuse it is. Here is a diagram of fuse block anyhow. CIG stands for cigarette lighter.

you have overlaoded it, the wires behind the cig lighter might be melted.

it should be listed next to the fuse or on the cover of the box.

If the cigarette lighter does not stick when you push the lighter in then this is the step to take. The prongs inside the lighter adapter have been pushed too far out. ( This happens if you plug other electronics like satellite radio or radar detectors) First, you MUST take out the fuse from the fuse box located under in the glove box. Second, look inside the lighter adapter (not the lighter) you will see two prongs that are supposed to be flared a bit inward. Simply get a small flat head screwdriver and pick the prongs outward but not too much. Do test trials with the lighter to ensure the lighter sticks. Plug the fuse back in and your lighter will be good as new. -Pete

Check ALL the fuses. pull them out an dlook. Also repace the one that is power for the dash/rradio/etc... even if it looks good.
If that doe snot fix it then pull the lighter out and test the wire going to it for power. If it has power then you might have a bad plug/ground. Replace outlet if so.
