2000 SSEi tail lights keep going out

[twinrotor]

the car has started randomly blowing the tail light fuse. the stock fuse is a 15A those last about 2-3 days so we replaced it with a 20A witch lasts about 4-5 days. this is getting annoying having to pull the back seat out to keep replacing the fuse any body have any ideas on why the fuse keeps blowing? im about to put a 30A fuse in it and just keep an eye out for smoke so i can find the short.

Check the harnesses where they penetrate the trunk rear. I replaced both mine because I had abrasions on the wires where the weather seal had popped loose on the penetration hole.

With this being a random thing, do you know if driving over bumps or rough roads might be the catalyst for the fuse blowing?

PS - Don't increase the fuses when you have these things occur...you asking for some serious damage in doing so.
