That was my thought and when I saw that the trailer used the chasis
for the ground, I installed a wire from each lights ground to the
connector/chasis ground point. My jeep has one of the factory
installed large round connectors and I use an adapter to connect the
four pin connector for the trailer. I though it might be the
connector adapter but I tried another one and it made no difference.
It is not the trailer lights. When I measure the voltage at the Jeep
connector, the left turn signal applies voltage to both the left turn
and right turn pins on it. The right turn signal works as it should.
The lights on the jeep seem to work as they should but the signal at
the connector is wrong.

If the factory tow lighting on a 2001 Cherokee is anything like the
same on a '93 Grand Cherokee, the wiring is quite complex. It
involves a number of connectors and 3 relays. I would get a copy of
the factory service manual to do your failure diagnosis. Without a
schematic of that system you are really shooting in the dark.

If all the wiring is intact, the turn signal/dimmer switch assy. is
where it all "Y's" together...
