Quite a puzzle you have that seems impossible, though such things weren't unusual in the old days of bimetal flasher units. The modern electronic flasher relay is designed to flash at a speed dependent on the amount of current drawn by the circuit so if a bulb goes out the speed doubles or thereabouts, giving the driver an indication something is wrong. Broadly speaking the flasher unit will operate as it is designed within a current range so if there is too much current flowing or not enough it probably won't work at all. The turn signal switch is usually a very reliable thing and as the left hand lamps light it is fair to assume it is working ok. If the switch is accessible it would be simple to measure the current being consumed by the circuit, which would be nearly 4 amps with the engine running at a fast idle. If it isn't then I suggest you revisit the lamp grounds and other connections. My instinct is to suspect the hazard warning switch. It is often an unnecessarily complex switch and wiring arrangement and often responsible for turn signal malfunctions. Mostly operating the switch rapidly for a few minutes puts matters right, though if it doesn't I suggest you check the multiway connector behind the switch.

it could be fuel filter, or fuel pump relay

have you tried epoxy?

????.. Do you mean it will turn over but NOT crank and run? Do you have at least a 1/4 tank of gas..?? When/how did this start... all of a sudden,, started doing it occasionally?.. Have you had anyone (mechanic) look at it yet? Megan, there is not a way to diagnose your problem without A LOT more information.

if it smells like sweet antifreeze, it is the heater core is not he A/C evaporator core. the core fails due to not replacing the antifreeze coolant before it goes acidic ... (not doing service here) are you getting leakage under the dash near heater box, blower area?

sometimes an unbalanced tire could do this

Here is a link to free wiring diagrams.

chk engine coolant temp sensor

may need a new dimmer switch (rheostat)

If your saying the blower runs intermittently, I'd start testing at the blower motor when problem is ongoing, if good voltage and ground with no blower action, suspect the blower motor. Did you use a test light to check voltage at fuses, as you can see, one fuse goes hot with the key on, the other fuse is hot all the time. The top wire in diagram for blower motor is voltage, the bottom wire is ground. Any motor that uses brushes and the brushes are worn badly, the motor may run intermittently.

The code suggests a timing issue, your timing belt could be stretched, or jumped, it's a bit involved to check it out, but there is a line on each timing gear to help you get them lined up again. If there is excessive belt slop, your valves will be opening a bit too late and possibly closing too long, and your spark timing would be retarded. It would be worthwhile to check your coil as well, you should have a beautiful blue spark coming out of it, if it's yellow, replace it.

Possible low fuel pressure. Should be 31-35 depending on which engine you have. Check to see what you have.

Could be the distributor or the coil by the sounds of it - coils can be effected by heat and fail

read the SM yet, its free, here it is again, posted over 300 times p0700 means your scan tool is a toy. (place marker for A/t failures) USA cars XJ jeep http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service 1899 right> typed wrong? tells you the park /neutral switch is bad, PRNDL the book also shows, where that is and now to remove it. "transmission"

Did you change the fuel filter?

if the distribuitor was not new or fully reconditined then it is possible that it is still at fault have the ignition timing checked witha timing light to ensure that it is correct ( most operate at the 10-12 degrees btdc at idle speed of 850 rpms with the timing light operating , if the light flashes all over the place , that indicates a distributor shaft that is bent , worn or has worn bushes as the light has to flash consistantly on the one spot to be a good distributor doesn't say much for the mechanic not to try to fix a problem that you have paid for but relates to his workmanship

That year jeep has had problems with the fuse panel being loose and the connections between the two halves are intermittent.

For the code pulled was diagnostic trouble code diagnostics done or was the O2 sensor just replaced > What was the code # P0xxx what . There are a number of codes for the O2 sensors on cars . They don't say replace the O2 sensor . diagnostics must be done , electrical circuit testing , plus other tests

all answers USA on USA cars,only. (exports are diffr) so if you didnt scan it when it fails, how would you ever find the truth? (if no errors. then it can be pure mechanical failure) the car has TCM a tranny brain. its covered in the SM, read that chapter yet. on newer cars if the Tranny overheats or engine both can go to LIMPHOME< but your car is not even close to new, is it? Jeep calls that LIMP-in. my guess (sux) is its the 4.0L engine with matching AW4 box Aisin-Warner it wise to know whats there first. before trying to understand it a FACT ! so did you google search AW4 boxes. , i bet not. but they are unique. as all different boxes are. is the CEL lamp glowing running, Check engine lamp PDC fuse 16 ok (4L,aw4) TCM power, must be good at all times. is the throttle valve cable to transmission stuck out? if it does, the TCM and trans will either go nuts, or shift way late. http://etereman.com/blog/fiat-transmission/the-popular-aw4-automatic-transmission-and-common-problems-associated-with-it the TCM shifts using solenoids, we check that the signals to said solenoid actually do go to the correct voltage levels in to 3rd. (you said stuck in 2nd) if that is ok, then the TCM did it job and the problem is INSIDE the box. end story, we use remote test meters to monitor wires driving. chapter 21 and 8w are free to read here any time you wish posted over 300 times the Jeep Bible (SM) http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service click XJ

Sounds like your Freon gas pressure is low. You may need to recharge it. Very simple to fix and should check that before spending a lot of money.
