The 20A fuse for the two lights in the fiberglass top has blown twice? Something is grounding out I guess...
 
Yep, those lights have the orange and white wires that run to each light from the fusepanel along the drivers side then up to the top. Check those wires along the run first. Also could be the cig lighter wire.
 
That's a good assumption /forums/images/graemlins/rotfl.gif
Sounds like you'va had to top off recently and when it was put back on you pinched the hot wire and now it's shorting on the body. Take an DVM and measure the resistance of the hot wire to the body when the bulb is removed. If the resistance is zero you have a short.
 
My buddy Rodney was having trouble locating a short. He got mad and replaced the tube-type fuse with a 1/4" bolt. Waited for smoke to start coming from under the dash, then pulled it out. Found the smoking wire and replaced it. Problem solved.

(Rodney eventually went to prison. Good Guy otherwise though...)

Maybe that's why Rodney's in prison ... not exactly the sharpest tool in the shed /forums/images/graemlins/rolleyes.gif
 
I'm 95% sure if you change your cig lighter, you can fix this. Been there done that. What could it hurt, its like $3.00 /forums/images/graemlins/thumb.gif
 
that happened to me once, i took the passenger side pillar over off and put it back on and the screw that holds it on drilled right through the wire that goes to the lights in the visor...you might wanna try that too
 
get a cycling circuit breaker 20 amp. connect that to where the bad fuse goes(with jumper wires) it will heat up then shut itself..hence cycling. using a compass when there is power to the circuit run it along the location of the wiring starting from the fuse panel. the needle will flucuate until u find the short.
i know it sound stupid but it wotks. it will work through the vehicle trim too.. maybe not that thick ass b-pillar but if u dont find the prob by then ur screwed anyway..i mean rewire time..
the color wire is orange coming out of the fuse box. and according to my wiring diagram the cigarette lighter isnt part of the circuit...but it may be wrong....good luck

I just figured out on my Blazer that the running lights are also on that fuse, not sure if thats the case on all blazers, but you might want to check if there are any problems with any of those lights /forums/images/graemlins/thumb.gif
 
my truck did the same thing, my horn, radio, and inside lights are all on one little fuse thing, so it ended up being every time i honked my horn it would short out.. the connection to the horn on the grill had came lose and was grounding out on the bumper.. check that! there are 2 wires, 1 for each horn.. its simple..

I just had this same problem. However, a damn dime flipped out of my ash tray and into the cig. lighter socket and shorted it out that way. If your lighter isn't in the socket you might take a look to see if something is lodged in there!!
