Check your gas cap, or have your codes checked sounds like evap leak

First make sure the coolant level is full. This should be done with while the engine is cold. If it's full than its most likely a bad thermostat, but could also be a bad water pump, or a bad electric fan ( don't remember off hand if yours has an electric or mechanical fan). If the water pump was bad you would not get heat out of the vents. If there is heat out the vents than the thermostat would be the most likely fix.

bad relay or bad logic in the BCM etc. first pull the relay. then find out if the relay coil is hot (socket voltage) if hot, the BCm is messed up use a scan tool you can not fix cars with no scan tool CAN'T ! scan it and see if there are DTC errors. if the BCm or PCM is showing ERRORS for that, then use those facts for why.. i hope the battery is not connected backwards, (sorry )

Blend door actuators could be bad, or vacuum leak in hoses.

you have a dead short probably in your ignition switch , you need to disconnect battery asap

run the dash cluster tests yet. http://www.fixkick.com/Jeeps/jeeps.html#cluster it has its own computer inside and self tests. you watch.

you cant.

L/R and V6 marks etc,? the fsm steps are many, got that? see these ? yet. the words reference these photos, so... here they are. pretty usless, sans words.

the 2002 has fixed spark timing, so must guess cam or balancer? no job stated, so i must guess, why make me guess? ok lets google search for you https://www.google.com/webhp?gws_rd=ssl#q=jeep+3.7L+cam+timing+marks ok that be all rumor right,? web pages, can be wrong, and missing many very important facts and steps all stated below. better for sure is: FSM book from https://www.techauthority.com/en-US/Pages/Home.aspx or login to alldata.com http://www.scantool.net/software/alldata-diy-1-month-subscription.html

You didn't say which sensor .,No sensor can be repaired..It has to be replaced new....however most cases you disconnect negative ground battery cable..Carefully disconnect connector wiring clip from old sensor..,Remove sensor..Lightly dab die electric lube to new sensor connectors..And lightly to mounting threads ..just snug sensor tight..Do NOT GET IT TOO TIGHT...plug connector..,connect battery and test drive..

This is a possible recall of the heating and air vent door inside HVAC SYSTEM..some of the doors will get stuck,open half way ,or break..Also it could be the actuator that opens the vent door..Sometimes the control switch can also be at fault...Be sure and check dealer for recalls on vent doors....The doors take a day to repair pending door location...This is a chrysler jeep problem..I am a Chrysler/Jeep Tech...

unscrew it ,and screw it back in. why not say why you want to. "symptoms" is the the 3.7L V6? cant answer until you say what engine, is there. 2.4L? here is the list http://en.wikibooks.org/wiki/Jeep_Liberty/Engines seems like we should start there, only about 10% here state engines with and engine question and 90% of answers are wrong for just that fact. or are generalizations bad (mine too.) Is engine knocking up hills"? or all the time, did you scan the PCM and see DTCs; for KNOCK? what?

Have you recently got any wiring done, like a new radio or anything? The only thing that I could think of is that there's a short in the wiring or maybe the fuse is bad. Try these answers if you haven't already... http://www.automotiveforums.com/t1078060-discuss2005_liberty_fast_battery_drain.html

Explain what a "knock sensor" does? Never heard of one.....

what's a "knock sensor?"

have a compression test done to check for valve or gasket problems replace the HT leads with quality leads run the fault codes check fuel pressure to the injectors

FRONT O2 SENSOR.

-If you see it leak then need to fix the leak area. If don't see any leak then it's internal leak and it burn all or blow trough the tail pipe. Good Luck Mai Lor

there is no need to guess. at all insert a ATC circuit breaker in place of that fuse. then with an ammeter, pull all loads on that feed. the FSM shows, whats there. log in and read that. i just looked, F10 in PDC< (under hood) right? is the trailer hitch fuse. F10>>>> CB >>>> relay, >>>> hitch. CB is the trailer circuit breaker. log in and read, at alldata.com for $15 and not work blind again. yes, i know books are (out of style) but do pay back cash. in saved labor and mistakes and guessing wrong parts.

what schematic number or amps.
