The temperature sensor has nothing to do with the temperature gauge . The temp sensor controls the fan operation and the CPU operations while the temp gauge sender unit is a heat controlled resistor that alters the voltage through the gauge. check that you have replace the wires on the correct unit .

Hi, From your description I understand that there is an issue only with the fuse-box. This unit usually contains only the fuses, sometimes a few relays. There should not be any electronics. I would start with writing down all connectors and relay positions, you have probably done this before replacing the box. Next, you should be able to trace the wires with a multimeter (Ohms). Check also for loose connectors, burnt fuses. As for the relays, these could be tested on the car battery, once you find the "coil" ends with the multimeter, or you could borrow working ones for testing. Please explain if there are more parts inside the fuse-box.

Light switch has shorted, internally, everything you describe is engauged by that switch, replace the switch. I hope this helps!

did you check the fuses ? relays? does it blow any air at all? could be blower went bad and blew fuse, or a relay failed, check fuses first.

Start at the right side of the tank and work forward following the lines. Looks like its right in front if the tank. The lines drop down sharply then shoot off towards the front and its right there where it levels off

Obviously, the front three are fairly easy to reach. The rear three are the real problem. The easiest way to do the rear three is to jack the front of the vehicle up, crawl underneath until you can see the back of the engine from the ground, get real comfortable, making sure the engine and exhaust are cooled down, reach your arm up and pull the boots, very carefully.... then replace the spark plugs. You will not be able to see the plugs themselves, but this seems to be the easiest way to change them. Make sure you have a swivel spark plug socket and extensions and replace the spark plugs with platinum plugs so you can get another 100,000 miles and make sure you have anti seize so you can remove the plugs again in the future. The golden rule is that the engine has platinum plugs in there now and there good for 100,000 mile, if there are no misfire try not to change them unless you think your close to the end of the spark plug life or the check engine light came one to indicate that there are misfires. Good luck and hope this helps. 

Hi! Have you checked the fuses under the hood with a test light first?
