    even if the fuse looks good, try replacing to see what happens.

    I put a 25 amp in it's place also.
    I think when water gets near the fuse it blows.
    Also this thing is under the cover next to the air box just slightly lower,the cover has lettering for jumping instructions on it.
    The fuse has a black casing type frame arround it.
    you have to pull up the frame"along comes fuse" then the verry thp of the black frame housing has a little hindged top with a rectangle hole in it that you can view the fuse through.
    Open the top hatch of this frame with little window,the window is hindged everybody!!!

I had a very similar problem. Power mirrors, dome light and radio stopped working. I spent a couple of days figuring out what is the problem. The diagrams didn't match very well to my car, the wires colors where not exactly the same than on the diagrams.
The solution: I have RHD version so I removed the plastic cover from below the dashboard on right hand side. I took a 15A wire and I put one of the ends in the rubber hole cover from the cabin to an engine compartment. I used one of 2 metal rails from a wiper. Actually I had to perforate the rubber which is located in my car on the engine compartment wall in the far right corner on the top. It is easier just to put your hand there (it is nearly impossible to see what you are doing, it is better and easier just to feel it with your fingers) with the rail and perforate it and after that pull the rail from the engine side with the wire attached to its second end. When its done remove an air filter and pull out a bit the fuse rail to be able to see its bottom. Under the fuse 18 there are 2 metal fuse fittings underneath. Pull out the fuse #18 and check which fitting is live +12V. Disconnect a battery. Now you have to remove a bit of isolation from the wire which is going to the fitting and attach to it the new wire pulled out from the cabin. Isolate it well with the isolation tape and push the fuse #18 back.

Now the hardest part of the job. Be patient not to destroy anything. Unscrew the fuse box inside a cabin to be able to have a look on its back side. There are 3 fuses which are responsible for a power supply for radio, mirrors, dome light and, I think, the power windows. Anyway, all of them they are connected by a piece of metal which is connected to a wire. Remove a bit of isolation from that wire and attach to it the second end of the new wire. Isolate it well. Reconnect a battery and check how it works. If everything is fine just put everything together in the engine compartment and in the cabin and click Yes to let me know I helped someone to save time and money :) Good luck!

Dome light, power door locks, radio not working

Hello! Check fuse #11 (15A)...Are your Mirrors and Wipers working? If that fuse is good and mirrors/wipers with dome, door locks and radio are not working it looks very much like a defective Ignition switch...send a comment...

Electrical wiring

You need to revisit the fuse box ,, there may be more than one ! If you think the dashlights fuse are intact , check by switching on/off the side lights while checking the fuse. The fuse beside the side lights fuse should also be a side light fuse. They are handed LH and RH for safety reasons and check you have both side lights in the front. Power locks may be a dash switch /plug connection. Worst case senario ,(temperarily) remove radio and remove any fault you may have introduced into the system . A small bulb type tester will be a great help ! Good luck

Okay I got in my car and when I was driving my theft light came on, and when I stopped and went to get out of my car, the alarm went off, so I disconnected something and my dome light and cd player don't...

If it's after market, just disconnect the power source. If it's factory, good luck! You might verify when you lock with the key, you unlock with the key. Don't reach through the window and unlock. (if window is down!)
A lot of cars are integrating the alarm and everything else through the radio. Have you changed or upgraded your radio lately? If so , you will need to get new code for the radio to match the car system.
Really hard to guess on an alarm system. Sorry!

Dodge Ram 2004 no dome lights or locks when key out of ignition

Sounds like you cut into one of the wires that that supply power when the key is may need to get a wiring diagram for the truck and trace the wires down.

Cutting into the wrong wires is not uncommon in todays newer cars.

Dome lights won't work or power mirrors

Ford's are notorious for electrical 'ghosts'.
If the fuses are all fine.. and the motors for the windows and the light bulb for the dome light are good... probably not much that can be done unless you want to give it to the dealer for diagnosis and repair, but they'll probably tell you they can't find the problem.

No interior lights or power mirror working.

The fuse for the interior lights has a yellow plastic holder
covering it. Full the holder all the way out, fuse and all, with a needle nose pliers.
Replace the fuse. Disconnect the power to the radio you put in before you do this. Replace with new fuse. Check lights. If light work, plug in radio. If fuse blows, radio connection is bad (grounded hot wire). Fix wiring, replace fuse, and try again.
You could also have messed up the multi-function switch
(turn signal switch). EVERYTHING go's through this piece of crapo switch, and it costs a fortune to replace. Do the wiggle test on the switch, wiggle it while trying the things that do not work, front to back of truck, NOT up and down like your turning the switch on, the opposite way, front to back of truck. If things flassh off & on that stopped working, yopu found the problem. DONT pusy too hard, push gently on end of stalk, there is a lot of leverage there!
