None of the warning lights work in my truck I checked all the fuses and their fine what else could be the problem ??

 

I dont know what year this is... but there's also relays that are for some the bummy lights... my 84 has different fuses and relays for the different lights... the brake and charge light has a singal relay either behind the glove box or under the fusebox on the drivers side... or atleast it should.... those relays are dealer only and pricy... so you may check all you bulbs and wires first... I got a wire diagram for an 84toyta

 

I have an 84. 4runner

 

The relays just help the car not use all of it's power on the bulbs, is that correct? I did the same thing with my HIDs and it fixed it, so it might work.

 

I could go with that... Im not sure how they work exactly.
But some times they "stick" which makes the dummy lights come on when there not actually suppose to.
An I know if you remove it when you lights are on due to alt problems it will turn it off...

Seems to be a rather popular thing. theres several threads on here about them. So people have taken the relay apart and fixed them...
