sounds like a stuck thremostat

Damage wires in steering wheel

check all vac lines running up to sprayers on hood. You might have bad pump, can you hear it when you attempt to spray? If not pump's bad

The rear wiper has its own pump motor. pull the hose from the wiper and have someone engage to see if there is a clog. do the same at the motor. if bo liquid comes out then its the pump. also check fluid level in reservoir as well as a possible secondary reservoir

Would need to scan vehicle to insure the wiper speeds are controlled by the General Module or a wiper intermittent relay....if relay...would locate and replace...if general module.....a reprogram or software update could be in order...possibly replacement. Scott, Porsche Master Tech 35 years

ok, must not be ASE rated mechanics???? sure. please post the symptoms , I can not understand your post. my guess is you mean the dash warning light with a kEY icon is glowing, well that is the Immobilizer. the operators guide covers all lights,. lost that? using both keys as sold with car new??? lost the spare? here is a DIY list, (my wild assumption)

1. Read the operators guide first (glove box)?
2. check all fuses for good (test them)
3. scan the PCM see if there are IMMO errors SKIM/SKIS etc.
4. the scan tool can show many errors, like wrong key, or comm errors or the skim module is dead or , gee the whole list of possible errors there covered in the fsm.
5. reset the battery , pull neg lug wait 15m, and put back. but may brick the radio, (it asking for codes) (or NAV if you have that)
6. that is about it DIY.

no scan tool?, no joy,,,, DIY.

If you can connect to the computer with a code reader see the data to see if the speedometer signal is present. The vehicle speed sensor send the data to the cluster and the speedometer. If you have a VSS signal and no broken wires or loose connections then the cluster is just no good. Do all the other gauges work? If they do then it seems the speedo is shot.

this is covered in the FSM book by jeep. per engine. non stated, so.....????? p0 are federal codes. (a standard) and is oxygen sensor reads wrong. B2 S1 is bad. S1 is the front sensor. bank 2 is the engine bank that has #1 cylinder. the heater in side is blown out. or the wires to it are bad..melted, cut, or connector to it rusty. the ECU only knows, the heater fails to conduct current. it sees the heater dead. replace it or fix the wires to it. same on all cars this. only bank varies. next time post engine size. the line up. some inline engines run 2 banks too, like calif cars do. not just V engines.

• 2.4 L PowerTech I4 (gasoline)
• 2.5 L VM Motori R 425 I4 (turbo diesel)
• 2.8 L VM Motori R 428 I4 (turbo diesel)
• 3.7 L PowerTech V6 (gasoline)

the left front cylinder is #1 on v6 Bank 1 IS LEFT http://www.fixya.com/cars/t3949859-firing_order_diagram_02_jeep_liberty seen here. if this is your V6 engine, the 02 (b2) is on right , front (means upstream) bad. does this help, the inline on calif engine, inline it is rear top sensor. B2S1, on split exhaust manifolds. for calif.

its misfiring ever do a tuneup this decade? if it flooding it will misfire, and will stall. and will be hard to start. if at all, until all that fuel evaporates. the operators guide covers this, flooding cranking + WOT, crank with throttle wide open throttle clears most flooding. many cars do get worse parked a long time. that is what they do. seen spark wires go bad, and TPS go bad (really just worse) the spark wires old love to suck up water, and then short. which engine? Do the tuneup then use a scan tool cranking, to see if you have DTC errors. make sure its dont flood. do if the spark tips are soaking in raw fuel that is flooding and the test. (for 100 years, now)

Could I ask why you changed the waterpump in the first place?

its gears are bad. or is jammed and the motor clutch slips. the track must run free. or the motor will overload. its just a simple motor and simple mechanics. i remove motor and move parts by hand to see if jammed. if not jammed its motor new time.

steam is never normal. sorry ! use a $5 stethoscope and find object that make said noise. or get it serviced, i cant guess reality, not ever, that be god like. but if you can get it to a shop and not overheat the engine it may be ok. but noises , can be very very serious. the engine,. the accessory parts can all make noise, what makes noise is key here, and no net bunny on earth can guess it. it must be found. by a live human.

bad door switch, dunno which one doing it though ~ can be electrical or maybe the switch itself is stuck gotta trace which one it is that is not working

Faulty door switch. Pretty easy to replace.

what engine why anon, so we can see all your posts and context of all.

sounds like there is a problem with a cable sticking somewhere

6 or 8 cylinder ?

Why would you bleed a fuel line? The electric pump, if it is giving good pressure, will deliver plenty of fuel. Any codes? What codes? At this juncture, it could be nearly anything, including a low pressure delivery from the pump. Tell us more so we can help you better!

wow not going to say the job> ? heads off or what? 2002 Liberty.? KJ car. (USA) ever seen a real FSM? "factory service manual" and all those steps? to do work on that engine. http://colorado4wheel.com/manuals/Jeep/KJ/ here it is , read it, then ask questions?

wow no year stated, not that is a challenge. there is no such thing, the PCM is hard coded for all idle speeds. hard coded !@ (page 1 in FSM , under topic IDLE) and by LAW. (usa answers, here on usa forum) why not post the reason.? (running a wench? ) idle is wrong, not spec. (800 is typical or faster on A/c On) in fact the PCM works overtime holding idle at spec. shift that A/t to DRIVE, see the idle hold to spec and not drop. bingo. a working IAC/ISC idle control system (its a servo loop system) tell more, get more.
