I have a 2001 envoy. The trailer running light constantly blows. ( The one under the back seat ) I have no trailer hooked up and the fuse will still pop. Today for the first time I noticed after I had changed the fuse, about a mile down the road my left turn signal light came on very dim for only a second. I pulled over checked and the trailer running light fuse was blown. I had no trailer on. I also noticed that sometimes, and I mean sometimes when I activate my left turn signal it will flash on my dash very fast. Other times it will flash very fast only after I press the brake pedal. 90% of the time it will work fine (turn signal that is) The trailer brake fuse under the back seat is still blown. I only mention the turn signal because I think it may be linked. I should have posted this months ago when the weather was nice as I will be outdoors fixing it. I will give anything a shot. I may just run a new wire from the fuse box to the female trailer plug mounted on the vehicle. Will probably do this if I get a sunny day in the 40's. If I get one before spring. Again this all happens when NO trailer is hooked up to the envoy.
Thanks for any suggestion.
