may be it is dusty, also may be you should to check the fuel pump fuse. If after checking the inertia switch and the fuse you still have no power, you need to check for a broken wire with a volt meter. above just my opinion.

Check with a test light at the head light switch for power. If there is power. go to Headlight Relay.

try change fuse under dash board..if not on the side...try it..if that doesnt work there is normally a fuse board under the hood.. try there to.. if that doesnt work... then i can help...

under hood locate the accessory fuse pannel change master or accessory fuses
they are the big square color fuses not the black squares

they arent available from most gas stations but some parts stores carry them
failing that try the local salvage yard cause there they are 2 pockets full for 10 bucks or cheeper
if you gona go for fuses take them all inc the releys as they all burn out sooner or later

You can disconnect your battery for 15 minutes or pull the fuse for an ECM or PCM fuse, but the best way is to visit any local repair shop. Most shops will have a universal Check Engine Light Code Reader that can quickly and safely reset check engine light trouble codes. It should take about 30 seconds.

Ask your local service center if they could reset the check engine light with a Check Engine Light Code Reader.

There is a little fuse box near the master cylinder for the trailer lights.

TOOLS: Ideally you will need a 12 volt test light and a Digital Volt Ohm Meter. But if you do not have access to these tools you only be able to visually inspect the fuse for condition.

MY IDEA: (1) Open the hood and look for a fuse box with large fuses and relays in it. The fuses in this box will be physically larger than the fuses you may be used to seeing in the passenger compartment. Power door locks and windows not only require higer current flow as well as relays too. (2) Once you have located this box remove/open the cover and look for any labeling to identify fuses and relays as part of the power door lock or window systems.

CASE A: If these system fuses test okay/pass a visual inspection (not blown to open the circuit), light the test light on both legs of the fuse or when checking with a meter have minimal resistance across the fuse then you should change your focus at least temporarily to the master switch in the drivers door.
Since both the power door locks and power windows are inoperative I would start my diagnosis at the master switch assembly in the drivers side door. Somehow you need to get the master switch assembly out of the arm rest to proceed with diagnostics.

CASE B: if the system fuses didn't test okay/fail inspection...you will need to get the master switch assembly out of the arm rest and remove all the connectors to remove a potential fault to cause the fuse(s) to blow open.

Before proceeding I need to know what the results are (i.e. CASE A or B). This will indicate where we need to look next to run further diagnostics.

I know I haven't mentioned the radio symptoms but my suspicion is that it may be coincidental or resolved permanently with repairs to the other two systems.

Hope this helps.

It sounds like the cruise control switch on the master cylinder (if youhave cruise control). It's a Ford recall.
