93 Grand Cherokee no rear park lights

YOU MIGHT HAVE A BURNT OUT RELAY IN FUSE COMPART UNDER YOU CARS HOOD CHECK THAT OUT THRU YOUR CARS MANUAL,IT WILL SHOW YOU WHICH RELAY IT IS?

Could be as simple as the park light fuse is blown.

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.

There is a plug under the dash, directly under the steering column, that sometimes gets unplugged accidently. From what I remember, it's white. Check to see if any of them white plugs directly under there are slightly unplugged. Happened on my 93 grand cherokee once and I almost got rear ended from having no brake lights.

hello Anon.
battery charged, fuses good, F10 is RR. park
trailer wring hacks? (inspections find that) and collision damage there RR.
does RF work with RR fails>? both ends of car have park and blink.
I avoid Tail word for that one fact.
if you scan the PCM with a scan tool, are there DTC errors.
not scanning makes work 10x harder.!

"rear right tail light and blinkers do not work." both are dead? "and"
then turn off parks and blinks start working?
maybe the parks and blink wires shorted to gether.
what does not work mean, dead, or stuck on?
all key facts in diagnosis. all that.
i have 2007 GC FSm.

there are 4 elements (lamps actual there)
park is seperate from blink , totally.

the MIP module under hood drives turns off sperate drivers.
LF, RF ,LR, RR. so RR is bad. and not related to front like old cars.
park feed
all park lines go to a single point, the park relay 7 output.
so if something shorts to park all parks mess up.
each line has a fuse. so each can die by self.
There is only 1 park relay #7

so my question is, do any other park lamps mess up.
you said the blinks and parks (tail) do not work.
so? what about all park lamps. side and front.

if only RR fails, no other symptoms, i concur, bad ground. there.

a volt meter can measure bad grounds
with wire to battery neg,
and red meter at ground on lamp base.
if not 0v, or less than (0.5v) a 1/2 volt, its bad.

If you are sure it is not corrosion at the bulb sockets then it could be the back-up switch at the transmission.

I have taken my car to many shops to solve this problem. Long story short your tail light has a bad circut and entire lamp must be replaced. (Lamp cost approximate $130.00)

Check to see if you have inadvertantly hit the push switch on the rear dome lite. Click it once and try
your lites again..I had this happen on my 93 jeep and that was the problem.

Here is the stereo wires which may help you figure out which are not the ac wires etc. hope this helps with some of the problem.
