Front parking lights work; rear parking lights don't. Is there a fuse other than in the fuse panel for the rear lights? Where else would I troubleshoot?

IN THE FUSE BOX. (CAB OR BAY_)
THE OLD USERS GUIDE AND THE SERVICE MANUAL COVERS FUSES.
PARKS = TAILS
PARKS ARE FRONT REAR. BOTH
SO ARE BOTH ENDS OF CAR DEAD FOR PARKS?
THE FUSE IS MARKED "TAIL"
AND RUNS ALL 10 PARK LAMPS ON THE CAR.
THE PARK FEED TO TAIL OF CAR PASSES TROUGH A LIGHT FAILURE SENSOR ON 4 REAR TAIL LAMPS ONLY
THE SENSORS IS OPTIONAL AND NEEDS FUSE "GAUGE" NOT BLOW TOO., THIS OPTION SO FITTED, HAS CLUSTER LAMP CALLED
"REAR LIGHT " WARNING

REPOST AND TELL WHAT ALL 10 PARKS DO.
OTHER WISE HUGE WORK DOING THE HARDWAY

FRONT, REAR AND SIDE MARKER ARE ALL PARK LAMPS
THE LEGACY NAME TAIL IS STILL USED BACK TO 1920.
SO IS A TRADITION BUT BIG TIME CONFUSING WITH 10 LAMPS.
LIKE SAYING MY FRONT TAIL LAMPS ARE DEAD., SILLY.

Do the front park lights work? The front and rear park lights should be on the same circuit. If no park lights operational, possible switch or power/ground issue. If only rear park lights not working, suspect burned out bulbs/wiring problem to rear lights

No relay for the parking lights .
When the headlamp switch is moved to the PARK or ON position, battery voltage is supplied from the 15A Park Lamp fuse to circuit 9. Current flows through circuit 9 to the instrument panel fuse block (IPFB). Battery power passes through the IPFB to both license lamps, both front and rear tail lamps, both front park/turn lamps, and all marker lamps through circuit 9. The front marker and front park/turn lamps are grounded by circuit 150 through the forward lamp ground splice pack. The rear tail lamps and license lamps are grounded by circuit 550 at the rear ground splice pack and the right rear body ground.

There are 2 fuses for parking lights left and right side. so it can be 2 relays. located in the box in the front.

the parking lights in the back are not working? i would check for a pinched wire or bare wire on the front lights, did they replace the bulbs when they did the repairs? the front and rear parking lights are on the same fuse.

Since these lights will work auto or manual is there a relay that might be bad. You mean these light's won't work auto or manual ????
Did you check the TAIL LAMP LIC LAMP fuse 15 amp . ?
Located in the right I/P fuse panel open passenger door plastic panel end of the I/P pull ,fuse box behind . This fuse takes care of the thing's your having problems with

Park, Tail, Marker Lamps, and License
The park, tail and marker lamps, including the license lamps, turn on when the headlamp switch is placed in either the PARK or the HEAD position, or anytime the headlamps are requested. The RT I/P #1 fuse in the RH I/P fuse block supplies battery positive voltage to both the park lamp relay switch contacts and to the park lamp relay coil circuit. The park lamp relay coil is controlled by the body control module (BCM). When the headlamp switch is placed in the PARK position, the BCM energizes the park lamp relay coil control circuit.
Current flows from the park lamp relay switch to both front and rear park lamp fuses and to their respective park/tail lamps. The front park lamps are grounded at G101. The rear park lamps are grounded at G302. The license plate lamps are a part of the rear park lamp circuit and are grounded at G302. The inadvertent power control feature prevents the park lamps from remaining on more than 10 minutes if left on. If the park lamps are turned on after the ignition switch has been turned OFF, or is in the ACCY position, they will remain on until turned off or until the battery runs dead.

Did you the REAR PARK LP fuse 15 amp in the right insturment panel fuse box.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????18
