My 98 GS400 will not signal the door ajar light on the dash or the courtesy lights (Top and puddle) won't light up when the read doors are opened. The front doors work fine. Anyone else expereince this problem and know what the solution is. I don't think it's a fuse because all the courtesy lights are in the same circuit.

Any help is appreciated.

 

You got a bad door actuator. Use the search function under ' door actuator' you will find a lot of useful info.
