perhaps because you do not service it properly . How would we know

scan the PCM, it will tell you what error you have, called DTC's
what other cars did is of on importance, what matters is your car.
lets say the connector is just dirty.
the side of the transmission shows what model it is.
my guess is this is the 545RFE transmission 4x4, right?
got P0706 errors, shift lever , errors? (just a wild useless guess but i'm illustrating why you need to scan it)

here are all those connections. which are failing, takes testing..

see the video yet , "how it really works"
23 seconds into VID, the switch top right below is not where you think it is.
id re-seat the big connector and pray....


the driver shifts to drive.
the cable moves to drive.
the transmission TRS switch lands on Drive
the transmission TCM(in the PCM) tells the PCM you are in DRIVE and the PCM tells the BCM to tell the cluster you are in drive.
using the CAN-bus comm network.
not like a 1993 at all. not even close.

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...

Then a fault is still present, TPMS sensor(s) MAY be at fault

2005 Jeep Grand... | Answered on Jun 17, 2015

PO204,205 are injector circuit malfunction,PO174 is a system lean code, PO175 is system rich code, PO138 is heated oxygen sensor bank1 sensor 2 circuit high voltage, PO158 is heated oxygen sensor bank2 sensor 2 circuit high voltage. This is a repair for your mechanic. When they fix the injector and o2 circuits the rich lean codes will also be repaired. Continued driving will ruin your catalytic converter. Good luck

This sounds like it could be the solinoid on the fuel pump i would try changing this first
Hope this helps

2005 Jeep Grand... | Answered on May 09, 2015

will it start with a jump? check battery for full charge, maybe alternator is not charging, check battery connections all the way down to starter, check selonoid by cross jumping terminals to engage starter.

2005 Jeep Grand... | Answered on May 09, 2015

was your battery dead did you need a jump start if bat was dead maybe in security mode need code to turn on

2005 Jeep Grand... | Answered on May 07, 2015

is bad, the CD drive is bad.
you have choices.
1: check all fuses.
2: replace it. $$$$$$
3: get it fixed $$$$$$$$$$$$$$ ($50/hr x4 ? and parts, nah....)
4: dismantle it, and unjam it , clean it, make sure no broken CDs in sided or labels fell off inside, or other alien objects inside, blow it out.(canned air) (silent prayer?)
4: upgrade to a head end with USB port and run USB mem stick with 1000 of songs off a stick the sizes of a Chiclet gum.

id go with #4, upgrades are a big win..

2005 Jeep Grand... | Answered on May 03, 2015

fuses. first.
then if bad, unplug it. wait 1 hour and plug back in.
if not good now, time to get it serviced. as opr guide directs.

is it just for illumination? (park lamps on)
if yes,that is a bad lamp, if all illum lights blink that is a bad dimmer.
if its a lamp for something else do say???????????

2005 Jeep Grand... | Answered on May 02, 2015

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.

When the temperature gets below freezing and you use a bargain windshield washer fluid or plain water, it freezes and won't work. I normally drain every drop, not just add to what's already in there, and refill with Prestone yellow windshied washer fluid that has a lower freezing point.etort
