If a 4-way trailer connector tester like part # I26 shows that the drivers side turn signal on the Curt T-Connector Vehicle Wiring Harness part # C56344 for your 2014 Jeep Compass is constantly hot then you would first want to remove the driver's side tail light assembly. Once this is done you would then need to remove the connector to the harness and inspect the pins making sure none of them are bent and or corroded. If they are then you will need to clean them up with some electrical... view full answer...
Yes, a short on the trailer wiring will take out the converter on your 2008 Jeep Compass. You will need to inspect the trailer wiring on the left side of the trailer to locate where the short is and repair it.
The LED lights on the trailer will not be causing any problems with the converter.

This may seem like an obvious suggestion but you will need to make sure the T-Connector Vehicle Wiring Harness, # C55050, is directly connected to the positive battery terminal on the vehicle via the included fuse and holder. Any other 12 volt source is not sufficient.
Make sure the fuse is intact and fully inserted into the holder. If you have done this and followed all of the other instructions and there is still no power or signals coming through then there could be a problem inside... view full answer...
T-One harnesses, like the Tekonsha # 118539 for your 2014 Jeep Compass, shouldn't have any functional effect on your vehicle's tail lights. With the included Powered ModuLite, the harness draws power directly from the battery instead of your Jeep's electrical system. The Modulite converter is also designed to protect your factory wiring from any potential backfeed coming from the trailer side, in the event there's a short on the trailer wiring.
With all that in mind, it sounds like two... view full answer...
Yes, I believe that that corroded bulb is something that is affecting the lights on the trailer. There is definitely a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light.
Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free... view full answer...
That is definitely not a good sign but it's most likely that you just need to unplug all of the connectors and plug them back in to clear any possible connector seating issues. Also make sure the power wire is connected to your battery and the fuse is good and installed. view full answer...
Sorry to hear about the issues you're having!
You can test the Curt harness on your daughters 2018 Jeep compass to confirm if the module went bad, or if there is another issue some where.
You'll need a circuit tester like # PTW2993 and test the right side stop/brake function that's not working.
What you'll need to do is turn on the right turn signal and test the wires that T into the right brake light and going into the module. If there's feeding the module, then double check the that... view full answer...
A bad ground can cause all sorts of problems, but I am not convinced this is a ground problem. However, it could be beneficial to try to move the ground location to see if that helps.
Wiring harness # C55050 receives power for the trailer lights from the vehicle battery and only a little bit of power and signals from the vehicle tail light wiring. If the power wire is not connected, the harness should not work.
Try disconnecting the harness from the vehicle tail lights and plug the tail... view full answer...
It very well could be a bad ground connection between trailer wiring harness # C55050 and your 2010 Jeep Compass. Make sure that the white ground wire is attached by itself to a bare metal surface. No paint or coating can be on the ground location surface.
Also make sure that the fuse is inserted in the included fuse holder and that it is not blown.
If the trailer lights still do not come on, then use a circuit tester such as # PTW2993 to test the 4-Way end of the harness while someone... view full answer...
It sounds like the 4-way tester you are using like part # I26 has a short somewhere which is in turn causing the 10-amp fuse on the Curt T-Connector Vehicle Wiring Harness part # C56344 for your 2013 Jeep Compass to blow. What I recommend doing is testing each circuit with a standard test light like part # PTW2993 to check for function. If all is good, then you know the problem was in the 4-way tester you are using.
All of the converter boxes used in Curt's wiring harnesses are tested... view full answer...
