One of the dash board lights on my 2007 toyota rav 4 won't cut off, what is wrong with it? It's not the oil light

Do you have the dash light dimmer control turned down by chance?

No.
Someone could have unplugged the switch, or the switch could be faulty. Or the bulb may be burned out. The light should come on if the switch circuit is grounded.

start with the checkk engine light , scan the car and give me the code number , some thing els make sure that your battery is good

The flashing check engine light means there is a serious problem with the performance of the engine. You need to get the computer scanned for trouble codes next.

Check your fusible link.It is tied into positive battery cable,goes to starter and alternator,it is burnt up.

possible the oil sender unit is faulty should be an easy fix, matter of replacing sensor.

fuel lights these days in modern cars come on for more reasons than just having little fuel left in the tank. toyotas electronics are very reliable and not too complex. but this could indicate a couple of reasons 1) the fuel filter in the tank is dirty. 2) the sensor for the fuel capacity is defected. and 3) the wrong fuel is messing about the injector system.
a diagnostic machine should locate the problem very quickly. good luck

duh what
that question makes no sence

time for an oil change

This warning light indicates a problem with the rear lights (Brake lights, Reverse lights, Number plate light)... Normally it is set off by a bulb that needs to be replaced but it has been documented that using incorrect Watt rated bulbs can also trigger the warning light. It has also been noticed that faulty wiring may trigger the it too.
