All turn signals on my jeep cheroke laredo are not working. Is the problem a bad fuse??

It can only be a few reasons

Bulbs,
Fuse
Relays,
Switch,
Wiring.

It is a known issue

The "20 amp yellow" is a fuse.

try fuses, first, for 10cents.
first know how it works.
then diagnose it.
saves $$$$

1998 last year of ZJ jeeps.
FSM book, open to chapter 8w.
go to page on ext. lamps turn/haz
page 52 (ive posted the free book 100s of times, no more)

haz ok, truns dead on 4 corners
does the cluster flash when turns dead? on corners 4.??>?>?>
the 2 fuses are F13 and F6 in the JB (cab box = JB)

the cluster has 2 lamps, left and right.
if cluster is dead, that is a bad switch

this is how it works.
can be a bad connection at (see small arrow red/)/?

The parking lights and turn signals are on two different circuits.
Have you checked the parking light fuse ?

Tail light/ dash light/ license plate light fuse is blown.....one fuse lights them all up.

But they have different switches, right? Check the turn signal switch.

sounds like a fuse have you checked the fuses?
if fuses check out ok look for bad fusible link

check fuses. or the switch behind the break pedal. good luck. [email protected]

It is possible you have a bad "combination flasher"
