My 2001 TJ's (4.0 5spd Sahara) turn signals have been intermittently not
working at start-up after the Jeep sits a while (as short as ~50 minutes).
Hazards work, but moving the turn signal stalk up and down results in no
clicking or lights. The signals remain inoperative until the vehicle is
driven, usually only a short distance (across parking lot to perhaps a
quarter mile), then all function is normal. Dealer has replaced (under
extended warranty) first turn signal stalk/switch and today the flasher
module under the top of the steering column. Here is the seemingly weird
part; tonight the turn signals again did not work (hazards work OK) after
the Jeep sat a while; moving the stalk did cause a faint flicker of the
signal indicator on the instrument panel that wasn't visible during the day.
Also, I noticed that with my foot on the brake, the brake light would go out
on the side the turn signal stalk was moved to until the stalk was moved to
neutral. Seems like the stalk is switching OK and what ever cuts current to
the signalling brake light is working, but the lights don't flash. I'll
relay this all to the dealer but I would love to here what the guru's have
to say. I am going to let the dealer have the vehicle while out of town so
they can see the problem first hand after it has sat. These intermittent
things can be a real pain to track down I know. I'll let you all know the
problem is in any event after we get it tracked down. Thanks for reading.

I'd start checking the wiring and the body grounds.
Almost sounds like a bad harness, but can't rule out a bad
ground connection.

Second thought. Do you have a tow hitch and lights? If the socket
or the wires running to it get damaged, that can cause problems.
(not very common, but worth checking)

I owned a 2001 TJ. There's a known problem with the switch component
in the steering column. I had similar issues and it took the dealer
three tries to get one that solved the problems. On mine the turn
indicators would stop working intermittently. After three new switch
components the issues magically went away.

I do have the Mopar trailer light harness teed into the wiring at the left
rear turn signal. I'll let the dealer know. Thanks.

bad ground for that circuit.
do you have tube type covers over your rear lites
i have seen those covers take the ground away from the lites and they not work
