If all your fuses are good, start looking at your ignition switch. It's the one thing all those circuits have in common.

Something is shorted. You have to find out what and where the short is.

check the dimmer switch, I had the same problem. this dimmer switch didn`t dim on low beem but went out on high beams, turned the dimmer switch up and down/on and off and it came back on.

the computer has an auto reset mode that if a component is faulty but not serious it will reset itself until workshop computer is connected,then if fault still exists it will show up on the fault memory.If the light comes on and stays on then worry......

According to my findings there is no differential lock on the 2004 RAV4.

call the dealer and ask them.

Please take the car for a scan. Your alternator must be getting bad.

You can find the fuse box either under the Driver's side of the dashboard or in the Engine compartment.

Try this solution, hope you can find the right one.
