Rear Interior Roof Light Problem - 2004 Yaris Mmt Vvt-I Engine.

[Prithvi]

Hi All,

I have recently purchased 2004 Yaris 1.0 MMT VVT-i engine. Made a mistake of not checking the whole car before purchasing it. Have discovered that whenever I put a new bulb in the rear interior roof light. Either the DOME Fuse under the bonnet goes off or the bulb gets fused. When the Dome Fuse goes off, my Radio and Central locking stops. Otherwise car runs fine. Eitherway, I am without any sort of internal light in the car. (On the other hand the small light in the boot is working fine). There is some kind of short circuit somewhere. Diagnosing this is kind of difficult.

Any previous experience or advise is much appreciated.

Thanks in advance.
