Trailer lights not working

I have looked the fuses over and can not seem to find the fuse to light the running/parking lights. The right/left turn works ok but is completely black back there at night with no running lights. Any help?

Year would have helped.
First check is for tail light power at your trailer plug.
If no power there.
Best to get a wiring diagram and fuse location diagram for your year an trailblazer.
A factiory repair manual or a All data online sub.

If a 02 I show a trailer park light fuse no 42

I found it yesterday in the box under the rear passenger seat. My original screen name is Jethro with complete profile but can not log back into my account anymore so forgot to fill out my new account name.

Thanks for posting back the find.
Was it blowed?
If so you may have a short someplace.
Good Luck

If you can not log in ask for a new password in the log in box.

It was a 10 amp and was blown. I have a tester for just this prolem and 80% of the time it in the lights/wiring on the trailer and when it happened to be a fuse I wasn't totally familiar with the fuse location. I will look the trailer over for short thanx.

I did attempt to reset my password a few times and get the link to do that but have failed to receive the emails with the new password. Must be a glitch in the system somewhere.

Today it worked!

They have been doing some work on the forum.
