Back lights, park assist, rain sensor, interior lights on console and right rear indicator stopped working the same time. all fuses good and only brake lights work. head lamps also working

does car drive.?
if it runs , is the CEL lamp in cluster out
is the charge/battery./GEn light OUT?>
is this USA spec car, or where? (Wiring varies by country)

check both fuse boxes, not just one?
2007 i think they went to 1 box under hood.
but 2005 is many box car, IIRC.
you need to scan the PCM first.
no scan tool?, no joy,
if it shows DTC errors, you need to post those first.

i have the FSM, ill look at one fail.
WK jeep Gen 3
ill do backup lights, as i cant figure others out, "rear indicator" mean R/R blinker or turn signals dead?

id need to drive car. (need all things working and not, , not just cheery picked)
id need to see if all cluster warning lights glow key on
and if i turn the HL switch to park does the cluster lamps glow?
called illumination lamps in cluster.
the GC is very complex electrical, not like some old CJ.
very complex.
(no problem) but we scan it first. why not do that. so we dont have to node test , vast things with my meter..... volt meter....
ok , no scan tool, for $10 (elm costs that and works)

do all exterior park lamps work (you said heads work but parks ,are they all good)?>
ok im in chapter 8W now, wiring.
100 pages deep....
back up page, 54-1, fuse 9
if fuse one is hot both sides the lamps glow.white.
the relay is controlled by Module front control (MFC)
if the model fails to close the relay , that means it was never told to.
if the PCM or BCM fails to see reverse selected or fails to communicate this fact to the MFC then the PCM or BCM
sets errors, called DTC errors.
it will tell you, for example comms are dead.
or the MFC is not talking
or other errors related.

your car has a network, if its dead, things die.
the network must be working right.
that takes just a fully charged battery, is it.
is battery at 12.6vdc rested?????????

no 10v. but 12.6 volts. (dont own a $10 volt meter? yet?)

the MFC is inside the MIP, module integrated power .
the MFC is messing up, my guess.!
it runs backups and blinks, even in the rear. dispite its name FRONT.
Id say the MFC is not bad, it;s
1: scrambled? (lost 12vdc power?) to it or weak battery.
2: comms to it are failing. (seems its half working,, implying to me garbled data transmissions to it , on the network.
scan it, or never know... why.
it can be reset, by pulling fuses. to it.
sorry for crapppy photos, on fixya,. they shrink it to near useless...

My left side tail light doesn't work after changing the lamp. Jeep 2007 - Commander

it worked before the change out?
there are 3 things that are first. on advance electronics, cars. like this. 2007 is 1st year, of wild complexity.
  1. check fuses first. MIP fuse #8,9,10 (8 is left) check that?
  2. check action of park relay
  3. check for trailer wiring hacks (do you have factory hitch option?)
  4. and scan the PCM , do you see any park fail DTCs'
DTCs are system errors.
that is first.
next if not solved, we look in the FSM for that chapter, and the schematics, to see how its is structured. (varies by year, car)

FSM JEEP XK 2007 (book)
factory service manual.

left side rear tail (park) (tail is old name , car has many park lamps now , not just 1 or 2 tails like in the old days.
so it park and the relay of same name.
there are front parking lights too... do those all work>?

my guess, is you didnt check fuses first.
am i right?
fuse 8 is blown?
but that takes out front left park
and left side marker (park ) lamps too.
so did you look at all left park lights first>?

i bet not, if im wrong then you do have wiring errors.
or the new lamp from china is shorted inside, (common)
try one more lamp , like from GE or Philips.

2007 mazda 6 front and rear driver and rear passenger windows not working.

The windows need to be re-learned.
- Park the car on level floor. Shift the gear lever to P or N. Pull up the hand brake. Start the engine.
- Sit on driver's seat. Lower the driver side window. Keep the button pressed for three to four Seconds after the window glass sits completely.
- Move up the window glass and do the same as above.
- Do the same with passenger side window glass while sitting on the passenger seat.
- Repeat the same procedure for rear windows one by one from their own buttons.
- Sit on a drivers seat and operate all the windows one by one.
If the problem persists, pull up the body diagnostic error codes with Diagnostic computer or re-learn the windows with the same machine.

2007 toyota corolla no lights, wont start

What did you plug in? I had a similar issue when I plugged in a high amp tire pump. It kept blowing fuses because the pump itself had a short. Be wary of using stuff like that in the cig lighter. I switched to a hand held pump. How was the computer found to be defective? I wonder if the cig issue shorted the computer?

2007 Jeep Grand Cherokee tail light problem. When the lights are turned on the rear right tail light and blinkers do not work. When the lights are turned off they work like normal. A ground issue maybe?...

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.

Sounds like an open ground. Maybe make sure the wire that is on the neg terminal is connected to the body about 6 inches away. Also a mechanic is responsible for his work for 30days. Every mechanic all over the world operates under this law. It is a law

2007 Nissan Versa gear shift locked in Park. My Versa will not shift out of park unless i push the shift lock button. What could be the problem?

There is a switch under your break padal, which is responsible for tail lights and gear lock. if that switch is working fine and your tail lights are working fine then check the electronic lock of gear which is under the cover of gear.
