Sounds like you have a slipping belt, but it should have nothing at all to do with the horn. slipping belts squeal. You need a can of this. Apply it twice a day apart.

There are two cables running to the front lights one for the running lights and one for the turn signals.

first have diagnostic test done to retrieve fault codes and to see what sensors come up as components related to fault

Inside the body control module(BCM). It's not a relay, it is a chip. If it does work with the switch or FOB, it is the BCM. if it works with the switch, have the FOB checked. If it works with the FOB, it could be the switch or wires.

all cars do that, called misfire , all do it never tuned up.! what mileage on that engine, from last tuneup.? and total miles 100k,? what? if that is engine buck and not transmissions slip or unexpected shifts. then that is called MISFIRE< and #1 cause, is bad spark plugs.(warn out as ALL DO) there are 49 more causes, but most times not on newer cars. ever get that car serviced, ? all cars buck ignored, all. for 100 year in a row. (gas) if the spark is good. we use a scan tool and watch for DTCs during the buck. the Scan tool will tell you , if the ASD relay drops causing said buck and why. there is no other ways... to fix, not bad spark plug bucking takes tools. I have 2010, same engine, in my priv garage. (Grand Cher) and its got fresh spark plugs in it. the are not easy to change out. ask. has COPs in the way. and more... use the best spark plugs you can find, to make them last longer and not have to pull those cops too often. also the cops have boots that can carbon foul. but the service shop knows all this stuff. let them>?

what 4wd drive system option do you have. command TRAC OR SELECT TRAC??????????? no photos of shifter so can cant be savvy. if you have the part time system, and drIving on dry pavement, stop doing that. stuck in 4LO is worse. why are you in LOW, the operators guide lost? free to get and read here http://www.jeep.com/en/owners/manuals/ THE RULES ON BOTH BOXES are same in 4 LOW. stay off dry non icy pavement. (axles are locked together then) start reading on page 333 the pages are for both transaxle systems. ive no idea at all what you have there, or what you are attempting nor if on ice or dirt. ???????????????????? part time, is only for dirt or ice. never on dry pavement ever. select track is ok, on pavement but never in LOW. RTM read how not to use LOW.

The first thing I would do is call the dealer and see if they show a part number for the instrument cluster illumination bulbs. If they do than its as easy as removing the cluster and replacing the bulbs. I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

how on earth would the blind know what is wrong.? scan it? yet? btw, newer cars cut cruise feature for any signs of danger. new laws... the traction needs ABS to work ,so forget that and fix ABS. ABS needs 2 things to work , brakes and ABS. so if brakes are bad, then ABS will get upset. after all, if it cant brake right, how can the puter save you? if brakes are known to be ok (inspections work here) but in this case it was BREACHED by you, with out reading the book first. then scan the ABS. (omg? code for dead sensor?) nah, you caused it.. easy ABS resets every key on. so... my guess, if ABS was happy before your actions( you never said) then you got air in to the system. and failed to follow the FSM instructions on bleeding brakes, in ABS car. front caliper, did you block the hose with cap, so it didn't allow air to the modulator? oops... never just let them drip... or . max pain. bleed it again, (using any or all 5 ways to do so, bleeding is skill thing) (many modulators can not just be simply bled) now Ill quote the 2012 fSM for you , under brakes Data: ----------------------------------------------------------------- ABS Brake Bleeding STANDARD PROCEDURE - ABS BRAKE BLEEDING ABS system bleeding requires conventional bleeding methods plus use of a scan tool. The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaining in the system. Perform base brake bleeding, (Refer to Brakes - Standard Procedure)(Refer To List 1). Connect scan tool to the Data Link Connector. Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then ABS BRAKES. Follow the instructions displayed. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed. Perform base brake bleeding a second time, (Refer to Brakes - Standard Procedure)(Refer To List 1). Top off master cylinder fluid level and verify proper brake operation before moving vehicle.

short block long. or long with all manifold.??????? the 3.7L fit , work, run, run perfect and pass smog? (all diffrent)! in some states they check engine serials and dont allow, down grades. (calif is one)

post in English please

it is stuck in anti theft mode you try disconnecting battery and see if it helps. You will have to reprogram as well.

Hi there:DTC P0456 trouble code which refers to Evaporative Emissions System, check HERE additional details to test.

it must be same part number and jeep told you it is not PNP, plug and play and must be programmed to work. and 99% off all returned PCM are perfectly good due to bad inputs, to PCM or output actuators are bad (injectors and relays etc) as we said for 50 years, GIGO (even back to relay computers, first ever) garbage in gets you garbage out , of any computer made.so far. why not scan the PCM and tell the DTC errors and get help or omg even tell symptoms of any engine.

If you have true 4-wheel drive as opposed to all-wheel drive and you were driving on a dry surface with four wheel drive engaged, you may have "wound up" torque between the front and rear drive trains. This happens because when turning, rear wheels take a shorter route than the front wheels and this difference has to be compensated for either in the transfer case or by slippery or snow covered roads, or it will bind, and the resulting pressure makes moving the selector very hard. You have probably felt this happening ("bucking") to a lesser extent when making tight turns while in 4WD in the past? If this is the case, all you have to do is jack up the front end - and preferably get both front tires off the ground. The jeep should NOT be running. If it was "bound up," this will release the pressure and you will probably see the front wheels spin a bit. You should then be able to move the selector back to the two-wheel or all-wheel drive position. Good luck.

2005, is old, the cop boot are bad too that old boots are $15 each an 10x less than coil + boot. best is replace the, spark is first, cant burn fuel (gas) with bad spark. my guess if you scanned it , you'd see P0300 errors, means all fail. or see P0301 and only coil #1 or boot is bad. or injector #1 is bad. scan it. not scanning the PCM means wild expensive gue$$ing beg,barrow,rent ,buy the tool or get is scanned in any shop USA> most COPs replaced where never bad, HV wires/boots/plugs yes. there are other causes.

• bad engine, (cant be fixed with new cops or injectors)
• bad spark
• bad injections means fueling problems

I say why fear scan tools? the pay for them selves, that first time used, it is now a free scanner.. see how that works? ROI? saved from shop labor saved from THROWN parts not bad..? Do it first . even blown fuses,(o2 sensor fuse blown)???? check fuses.

You do not want spark to coil, but from the coil to the plugs. This could be in the wiring or sensors . Even a theft deterrent on. Connect a scanner and see what you have.

Possibly the switch is faulty.

possible damaged or improper install--harness short --fuse blown

I would investigate for a wiring fault, although you seem to be having problems on a routine time line I expect it is just an intermittent fault, like a loose connection for example
