USA car, must we guess, #1 fact to know?
so front parks work and rear parks(called tails wrong) only rear bad and side parks good? cars can have 10 parking lamps. do they all fail., a key fact to know for what's wrong.
is real license lamp dead too (3 park rear)
I have KJ jeep service manual open now, (PDF) owned .
Daytime Running Lights - If Equipped<<< got this????? DRL
the uses guide is free from jeep 24/7,
no need to work blind. ever.
causes for rear dead
- BCM failing
- fuse 9 and 7 blown ,7 is left, so both are not blown.
- park relay bad.
- g304 ground bad,
say no to all 4
#5 is 2 bad lamps, buy them put them in.
g304 bad kills lots of lamps rear os is not that.
not told at all
engine OK and drives perfect and head lamps work ,high and low beams.
nor if front parks works
no if DRL is on the car (an options)
does heater blower work//
does radio work,
do dome lamps work doors open.
does the IP cluster work right.?
4 turn sigals all work and hazards.
stop lamps work
reverse lamps work.
if all works , but rears
then fuses are not blown
BCM must be good, or the park relay dies and all parks fail not just rear.
there rear lamps are both burned out or the REAR G304 ground is bad.
but g304 runs most things on rear,so it can not be bad.
so 2 lamps burned out, we test the lamps now.
not telling all good and bad, the answer is way too long
electrics are a complex tree structure.
