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.

USA car or export, got trailer hitch options>? front or rear mess up, which end of car messes Up???????? say what stays on means, stuck blinking, or glows solid? Do hazards mode fail too.>??? got trailer wiring hacks, or collision damage? (look) Hitch jack pin 4 shorted? got factory hitch option or Uhaul hack job. now lets do the overall view the Module integrated power, (very expensive) has 4 outputs for all blinkers on car, (independent) one for each corner of car, and more if export model ( is it?) so one hopes that MIP is not bad. $$$$ Module Integrated power (MIP for short) it is a computer too. so did you connect a scan tool and look for DTC errors related to BLINK(turns./Hazard) it gets commands from the turn switch, if the turn switch works, its ok (off it's off, & on it blinks or stick on front and or rear) so if that is all true then the left side is bad. (front or rear? ) but you never said , front or rear. so my answer is, replace all lamps on LEFT END OF car, that fails. lamps can short if hug brass metal base lamps. if new lamps fail,, then the wiring is bad, based on cost of IPM check wires very carefull on end of car that fails. and at hitch wires, or if had a hitch and some one hacked it in or hack jobbed it out. (shorts) that is it, 07 GC.

post code, DTC with scan tool we cant ever guess codes. mine a 2008 has like 1000 codes.

There are several different things that could make it misfire ! not just plugs ,does it have plug wires or is it coil on plug coils. Could have a coil breaking down. Does it do it in all driving conditions ? Idle , cruising speed ,under a light load and what codes .po300 random misfire or a specific cylinder misfire code ? P0306 cylinder #6 etc.

-Possible causes are Faulty Idle Control System motor - Idle Control System motor harness is open or shorted - Idle Control System motor circuit poor electrical connection - Faulty Powertrain or Engine Control Module - Vaccum leaks or damaged hoses or improper routing check for vaccum leaks first if this was helpful please leave good feed back Read more: http://engine-codes.com/p0505_chrysler.html#ixzz3Mq1J8Bho

Check on your motor you have some where a place how you have your number of your celynder

in the owners Manual.

check the adjustment of the sensor. check for loose wires to the sensor or replace the sensor.

Sticking brake caliper, bad wheel bearing, bad drive shaft CV joint, just to mention a few posibilities.

My man I know your pain... I have the exact same problem happening to me now... same make, year and model... I called a mechanic buddy of mine and he said I might have a "flat point" on my starter and if so this might happen intermittently... he suggested a replacement of the starter... But I think the other suggestion is also quite valid so I going to have my friend do both...

Is this the VIN plate number ? What do you need to know ?

with modern electronic ignition the need to change spark plugs is virtually non existent on a good engine as they never burn the centre electrode like old point systems did..100.000 miles on plugs is common but the HT leads will break down in the insulation so should be replace at around 50.000 miles

Hi where is the throttle control located in a 2007 jeep laredo diesel 3,0 liter not sure where it is can somebody help thanks

as a start i'd recommend using a fuel addative , i'm presuming its petrol , so get an addative that covers the catalytic converter as well as the valves ,injectors etc.A build up of carbon deposits ,varnishing, amonst others can coat the sensors, including the o2 ,which can cause these erratic symptoms , follow the makers instructions , particulary useful if vehicle is more of a stop start driving routine , keep me posted if you wish
