I have an 87 300TDT and for some reason the int lights came on and stayed on. I have checked the door switches and all seem fine. I have had to unplug the front ones to make them go out. Also the seat belt warning will flash constantly even when buckled up. Anyone have this issue before? Is there a delay solenoid or something like this on this model? I have had the light apart and it looks like a light to me. My wife is getting a little crabby with no interior light. Please help.
