which engine, why not read the free fsm. it answers there 2.5L or 4.0l engine? getting DTC errors, for this, if not its good. why not post symptoms or is ASD relay dropping out>? do tell and we can find true causes. see fsm see ignition chapter and wiring on topic, CKP ignition chapter 8d page 4 cover this, and automatic trans cars have a special way to installed it,. RTM http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service unplug it, and remove 2 bolts, its out? 1 bolt on 4liter read page 13 for details,, on install. note the 3 setups. and the word Adjustable. clearly and paper space, page 4, << if applicable there, answered for both engines and 3 sensors.

Did you or previous owner add any electrical things like winch, radio amp or lights hooked up to that fuze? If yes, rewire so they run on their own properly sized fuze. If no, you have an intermittent short somewhere. Get a schematic, figure out where the wires from that fuze go to get to the things the schematic tells you they go, then follow the wires looking for damage. If you cannot isolate wiring harness damage, run new wire taped to the outside of the existing wiring harness. It is possible one of the things hooked up to that fuze has an intermittent problem inside. A way to find that is to run a separate fuzed power to the devices (ignition coil, EGR, fuel pump etc). on that circuit, drive it for a while and see if that fuze blows. If it does, investigate/replace that device. This requires major surgery on the wiring harness and is not to be undertaken lightly, this is a big deal and it is hard. Big problem is to make sure the reconnected wires are reliable for the next 15 years.

Most likely is intermittent in starter solenoid relay Next most likely is key switch start connection intermittent. a tester will have to be used to find where the power is being lost from the start terminal of ignition switch to starter solenoid pilot connection to the main starter output power from solenoid to starter main contactor.

check with the spare parts department but there is every possibility the it will as parts are not changed from one model to the other unless there is drastic design change as it simply is not cost effective for the manufacturer.

need a code book

the problem lyes in your shift cable .maybe lubed but should be replaced

Sounds like part of the mechanical parts have come apart. Check past the motor for any mechanical parts that are disconnected.

what are the symptoms.? there are over 20. or so.

1. leaking DOT 3/4 fluid. , at every inch of the way, in system.
2. stopping distance increased.
3. pulling (steering changes as you brake)
4. locked up brakes, 1 or any of all 4.
5. noise
6. ABS OR traction control (stability) lamps glowing
7. ABS failure. of any kind.
8. DTC errors, from the scan tool related to brakes.
9. no hard pedal,
10. pedal drifts to the floor.
11. spongy brakes.
12. pedal play is wrong , or height.
13. power assist part of brakes , inactive.
14. DoT 3/4 fluid levels keep dropping.
15. rusty brake lines
16. brake hoses cracking.
17. im sure there are more, ....

no engine stated, nor if gas or diesel, none are same..... in the USA, all cars the same answer for 1999 which computer, PCM,. BCM, alarm SKIM, immo, what? all. 1: connect OBD2 scan tool, press clear codes. bingo. 2: unplug the super secret ECU memory fuse. (ask) 3: pull battery neg .lug and scramble radio codes, nav codes and learn modes. depending on options day one. ill guess, GAS and PCM Fues 22 in the PDC is it. hot all time fuse. (diesel is 24) page w8-30 page 2, (wiring here the only hot all time fues to PCM. (batt a0 ) http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service pull it for 5min put it back. the secret is out. dont ask dont tell.

If it is a power window u may need a new window regulator if its ur back gate window u gotta pull the panel off and check all the rods that go to the opening handle my rods were bent and caught in the regulator causing it to jump but wont go up or down

its mean is knock sensor 1 circuit mulfunction bank 1 or 1 sensor

check engine light will probly tell you whats wrong go to autozone

which engine? gas or diesel 2.5L or 4.0L gas? viscous fan , or electric fans.????? so it must not be electric fans so the question is how to get the belt over the water pump mounted fan, on mine , it fished it over. why not you? chapter 7 page 23 (wild guessing, engine) http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service its all there. to read

did you open the system up front? do tell all things you messed with first , then ask a question. got ABS? there are 5 ways to bleed brakes (not counting ABS) which one you using>?

1. Gravity (LOL)
2. 2 man rule
3. MC power bleeder tool.
4. tail end fitting reverse power bleed tool?
5. vacuum tool?

we can not guess that , unless said. and is key to success. that be first ,for sure. did you read the FSM to see how YOUR CAR IS DONE? no? why not? Real deal. https://www.techauthority.com/en-US/Pages/Home.aspx scanned? http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service see chapter 5, its all there, to read, then ask questions not clear in the book. page 36 is ABS bleed, read that if applicable yet? i bet you can not do this page, no special tool to do ABS. but you never said.

It says ? what says? the SCAN TOOL>?non GRAND, (no engine stated, so fail there 1st)my guess is you have a DTC and forgot to post that. why do that?the DTC is covered in the FSM manual, and shows what is failing.why not read the FSM and do what it says to do?ill no attempt to read the FSM for you,. and that vague error.why not log in to alldata.com and stop guessing. at parts.there is no reason to gue$$my guess at he DTC,P0500"or was it the P07xx series, all A/T errors.P1xxx codes are factory code, got them? need all codes, not just 1 of many. and using a real scan tool not some POS autozoned junk (free)p0500 is ASE jargon (best ) is VSS sensors. vehicle speed sensor.the transmission TCM monitors many inputs, and if they are badit can NOT shift, one such sensor is SPEED. MPH or VSSthe tail shaft all all 42RE transmission has a tail rpm sensorwhen dead the cars speedometer goes dead, and the TCMis at a lost to shift to 2nd gear, if speed is 0 all day.a hopeless deal there.if the battery voltage is not over 15v, its not overcharging, running.99 is a nice jeep, id fix mine, ive had many.the tranny has 2 speed sensors.the front sensor does not do MPH, its just engine tranny input RPMthere are 3 RPM sensorEngine, RPM called, CKPtranny input sensor that tells the TCM true clutch slip at all timeand if the TCC works or not.the tail shaft is the true speed sensor, vehicle speed, it\'s on tail shaft.my guess, is the tail sensor is bad and you replaced the front sensorP-0715 is a bad input sensorP0720 and up are output sensor errors.the 500 , is the 3rd sensor, the tail shaft sensor that runs the speedo1st google hit.http://www.jeepsunlimited.com/forums/showthread.php?548105-P0500-Vehicle-Speed-Sensor-Malfunctionnext time post real DTCsso we can jump on the exact part and the simple teststhe beauty of 3 sensors, is the transmission runs bettershifts betterand the OBD2 diagnostics are dead nuts, accurate.it can see illegal gear slips (bad clutch packs) in any gearand tell you. one of the best there.areif you had new car, with 9speed, good luck keeping that card house going.. really.

Just a chat room/forum here Have to figure that out on your own

They all do that it is not a worry unless it goes down to the peg and stays there, the faster the engine is turning, the more pressure it builds so at an idol it may drop to 10, or 15 lbs and that is plenty to lubricate the engine, as long as it comes up at a faster engine speed ?

is there a water inlet valve on one of the heater hoses? the valve is to regulate how much water goes in the heater core.

another possibility that happened to me is, the pink antifreeze (dex cool) slimmed up my heater core. i blew it out and my heat was back
