I don't kno which fuse is the fuse that powers my front left head light to see if its blown or not, i own a 07 jeep patriot....if your looking out the windshield it's the head light on the left.

The wiring module or switch has issues. Have a reputable independent shop. Not dealer or tire store look at it.

Which engine?

Hi Daniel,here's a video showing you how to replace your oxygen sensors. 2008 Jeep Patriot O2 Sensor Replacement Here's a link to your sensors. Bosch Oxygen Sensor 15124 Read 1 Reviews on Bosch 15124 They are both the same.Here's a link to the other one which is the same part number. Bosch Oxygen Sensor 15124 Read 1 Reviews on Bosch 15124

It is too lengthy a process to explain here...have you looked elsewhere online for a video showing you what to do? Look up "Replacing 2008 Jeep Patriot axle shaft" and you'll get something. I'm assuming you have some of the tools you'll need to do this like ratchets, sockets, jack, supports to hold the vehicle while being worked on, etc.

where are the controls set at for 4wd?
and is this dirt or pavement....???

old jeeps ran shared lamps, see the schematic of the combo switch.
then in 07, the BS went to max. "dah Chinese"
the 08 is a very complex car. electronics wise.
the owners manual is good for blown fuses or how to change a bulb
that is why they make the FSM, the size of you leg.

the newer the car , the more complex. some cars with CAN bus
there is one power cable and the BCM tells the lamps to turn on
by digital communication, to the lamps processor, yes, Chinese.
the Grand Cher. has this.

this saves vast sums of copper wire, (now horded? see wsj.com)
rule 2 on cars, and worse on newer
there is only 1 name on a fuse. and some go to 20 places.
the all time top fuse that does that is
aka: PARK/TAIL/RUNNING lamps, ( i like PARK)

there are vast parking lamps. inside (dimmable) and outside
which work and which do not. (side lamps are park too)
3 in rear. ,2 in front, other places.

missing the boat, the new cars can report power problems'
all you need is to get it scanned. using newer OBD2 scan tools.
even brake switch faults.
battery sense fail. ,
scan it, if you see CAN buss comm, fails, we fix comms first.
or get help here.

id not own any 07+ jeep with out the Full FSM.
not me and im an ET. (retired)

it is a 4x4 the 4x4 gear is in nuteral, and the diff lock is on, please turn off your diff lock, there must be a light coming on your instrumenatl cluster, or if it is an auto transmission the torch converter need to be check

According to the wiring diagram, the left and right low beams are connected to the same wire which is
vt/or. Check for power on this wire. Also check for a good ground on the black wire.

If it is just the left side the bulb is probably blown. fuses will take out both sides
