Taillights fuse keeps blowing in 91 gmc - 1991 GMC C1500

SOURCE: # 4 fuse blew out,

I KNOW YOU HAVE AN ELECTRICAL SHORT.WAS AN ALARM INSTALLED OR ANY OTHER TYPE OF ACCESSORY? CHECK WITH DODGE TO FIND OUT ABOUT A RECALL.IF SOMETHING WAS INSTALLED, TAKE IT BACK THERE TO STRAIGHTEN IT OUT IF NOT HAVE A AUTO TECHNICIAN CHECK IT FOR YOU.

Sounds like loose wires. Had a similar problem with my 03 Durango. Kept blowing fuses when I put them in. Came to find out my trailer wiring harness had fried and was shorting out.

there is a short somewhere.put a test light in place of the fuse.
the light will glow bright.when the short is removed,the light will go dim
