My tale lights our out and windows will not go down is it a fuse and what fuse do i need to change
all windows dead? not just drivers? (not stated)
all park lamps dead, all 9 outside lamps dead??????? 3 rear
2 front and sides.? dead, with HL switch to park position?
correct step 1 are fuses
step 2 scan it, the BCM will tell you why it can do its job.
it will.. in most cases.
there are 2 ways (and more) to check fuses.
1: test them all, works every time and takes no knowledge of system complexity. (using ohm meter or voltmeter)
2: read he operator guide and read fuse page. its there. lost that.?
3: read the FSM book or at alldata.com and it there. for sure.
can i assume all else works?, and drive car at night)???????
03 WJ jeep, it is , I have WK 10
so windows can go down so cant test up. on all doors.
Tail lamps. 03.
so front parking lamp work but not rear tail nor rear license plate lamps? that it? the parking lamps is the better name
other wise the front tail lamps out sounds funny.
JB box Fuse 6 runs all park lamps front rear sides and license
so did you miss those lamps?
the relay that runs the run all lamps. all park lamps. lots.
the BCM controls (computer body) controls that relay.
so if main battery is weak the BCM will go nuts. does car drive ok at night
there is no common demoninator for park and windows.
besides the BCM. it controls 31 major things in the body.
ill check that next. but not windows.
fuse 12 runs this. PDC fuse box under hood. 50 amps (huge)
ok there is a link from dead parks to windows
that is because the BCM sees you operate the switches
then sends serial commands on the CAN/PCI buss to the door window controllers.
so if you had scanned the pcm , and say gross can buss errors.
why not get the car scanned first and show DTC error you have
I'll BET LOTS>!
do the 31 other things work like wipers.
door locks dead.
drive to any shop and say scan my car and get all DTC errors , not just 1 of many.
