95 s10 blazer dome light problem

MY blazer's problem started out with the dome light staying on some times. It was a intermittent problen then got worse, It started blowing the fuse for the dome!(horn,tailgate latch) are on the same circuit,any ideas would be helpful! thanks

I don't have an answer to your problem. What I know is somewhere you have a SHORT. Just start checking wires start from the source or go backwards starting at the horn. In my mind the most likely is in the steering column ie: horn. Disconnect it & see if the problem is solved. Disconnect it before the column.
Do that with the other items until you find the problem circuit then start tracing.
