    Hello all...
    I have a 1989 Jeep Cherokee Laredo and it shuts off while I am driving it. I was stopped at a stoplight and it just turned off. Got someone to help push it into a parking lot with me and within about 10 minutes it started back up. This is the second time in four months that it's happened, but the first time it started as quickly as it shut off, as soon as i realized it turned off, it turned itself back on. After the second time i went straight to a car store and had them check the alternator and battery, but they are both fine. Any advice as to what it may be?

    i have a "95" cherokee, :confuse: the problem, the wiring connection has melted down,i replaced the unit, but could not replace the plug,due to there is not enough wire to work with inside the little space in the dash area. does this mean i'll have to replace the whole harness? and what caused this melt down to begin with. also, would I be able to by-pass the belt connecting the compressor as i don't need to have the a/c,which don't work anyway. thanks for any help.
  • Wanna bet its the crankshaft position sensor? Steve and Tidester, where do I put that
    permanent post? :) Well, its is on the back of the bell housing at 11:00 position. Takes 4 feet of extensions to get to comfortably.Costs about 60 dollars. Get a Haynes manual and it will tell you how to test it. Mine failed both tests. Yes it's easier to test it than it is to replace it. You can test it from under the hood, but have to replace it from under the car. Good luck, not a hard thing to do! Re-post if you have any more questions!
    Happy wrenching!

    WOW!!.. took a while to find it-even with the engine service manual from chrystler!!..you can tell engineers wrote this one!(haha)
    --assuming you have a 4.0 six cylinder,the thermal sending unit is on the driver's side of the engine block,under the exhaust manifold,a inch or so above the oil pan,about 3/4 the way towards the front of the engine..there should obviously be a wire going to it,so it should be easy to find now..
    make shure it's well cooled off,and get a drain pan to catch the anti freeze..you'd be better off to have the new one ready to go in,as from what i read,getting the air out of the cooling system can get tricky..
    --i'd get the old one loose,and be reanoably shure the new one has the same electrical connector,pull the old one ,and while it's gonna leak all over you,put the new one in as fast,and straight as possible!..
    DO NOT CROSS THREAD IT!!..if you thread it with your hand,it usually won't cross thread..
    good luck!! :shades:

    I blew the engine in my 98 Cherokee 4.0, so I bought a used 98 Wrangler 4.0 engine to replace it... Well it turns out the entire accessory system is different on the Wrangler engine so I had to swap out the Alternator and A/C compressor mounting brackets, the water pump pulley, along with three of the front cover bolts. I also used the old power steering bracket. I have tried every belt size you could imagine and I can't seem to find the correct size. The belt for the Wrangler is too big and the Cherokee belt is way too big... If anyone has done this or just happens to know the correct belt size, please help...
    Thanks.

    i assume that you have a serptine belt and are probly trying to install it wrong the cherokee belt should be the right one if you changed the mounts from your old engine i know the smoth side has to drive the water pump so it snakes around over the top of the pully

    lol! Thank you for bringing that up, I just looked up the diagram and i did in fact have it wrong... Thank you very much
  • I have a 2000 JCS and have the same problem with shudder when I go over 55mph. Has there been any answer to your questions as to which axle shaft or driveshaft. My question would be,,,,why don't the Jeep dealerships know about this problem.????? :surprise:
  • Hi guys, i just found this forum and it's been great reading it! I have a 95 jeep cherokee sport, 4.0L, straight 6..199K...blah blah.

    i too was having front end issues for a while, and the shimmies at 50-55mph. new tires/rotate helped but there was also a crack in my track bar.. just thought id throw that out there since it seems a lot of people here were having problems with that.

    anyways! i was just out getting some food and went to make a turn and discovered my jeep was very difficult to turn.. i stopped, checked my gauges (everything seemed fine) and started up again. same problem, very hard to turn so i pulled over and thats when i noticed antifreeze spewing everywhere. just wondering if anyone knew what this could be? i plan on taking it to my mechanic on pay day, but was interested to see if anyone had any ideas. hopefully its nothing major.
  • Just where was it spewing antifreeze from?
    Hose, water pump, etc.

    Hi everyone, I'm back again with more ac problems...I have a 99 Cherokee 4.0 with 123k. AC died last year, Dealer said the evap coil was leaking and would cost $1200. passed on that and had it sealed and charged professionally this year at a local mechanic. Its been ice cold since April but this week it started to blow COOL but not COLD. One would think the leak is back causing the change, but I put a guage on the low side and its cycling between 55 and 80 PSI, which indicates overcharge, I have not added anything to it since the Mechanic charged it. I am not seeing a drain puddle underneath the car anymore or on the floor, but the compressor is cycling. The aluminum lines are frosting up, but not the condensor ( or whatever that bottle shaped part is at the firewall on the passenger side.) Any Thoughts? Thanks, Ryan
  • Got the handbrake idiot light on, checke pads shoes and fluid level. All look good and function properly. Do you know what else causes that light to be on? And yes handbrake is off
  • Hello, I have a 1991 Jeep Cheerokee XJ. The steering gear has breen creaking for some time now. Everytime I turn the wheel it pops and groans. My question is: are the steering gears servicable? If so where? I can't find any openings other than power steering.

    I have a 94 cherokee 4.0. I have had it for only a little while. Already I have fixed the vacuum hose for the heating/ac and replaced a fuse for the blower motor. Can I get a A/C recharge kit and fill it myself, could have sworn someone told me I would have to take it to someone??

    Also I noticed yesterday that there was something hanging down from under my front bumper. I got under there and it looks like a dust guard or debris guard that protects rock kick up from getting into the belt area it is not going to go back up (its worn). What is it and where can I get another I live in the desert in arizona and there is a real need for it here??

    Send me an email through my name mikevt1 above. I appreciate it

    Looks like I had a faulty guage to check pressure with, the system was low on freon and got nice and cool when I added a little freon, The AC is the only real problem I have had with this Jeep for 6 years now, but its been a pain since day one.
  • loosenutloosenut Posts: 165
    the brake light,just like a oil light,works when it gets a ground.. to check it,unplug the wire going to the switch that turns it on..on the brake system,there is also a wire going to the proporting"splitter" valve..it's where the front and back brakes split-follow the lines down from the master cylinder..there should be a wire there..if you unplug that wire,and the light goes off,you may need to bleed the brakes,or have them serviced professionally..
    ..try unplugging theswitch on the hand brake first..whatever switch you unplug-then the light goes off,that's where your problem is..
    electrical problems can be some of the most difficult things to track down..

    of course,you could always do the un-approved method,and pull the bulb!!(lol)!! :sick:
  • I recently had my rear drum brakes replaced, everything's new, lines, drums, everything. I replaced the from disc brakes with my brother, but the rear brakes squeal like crazy once I get moving. I'd say after about 5 - 10 minutes they become audible. Does anyone know what might be causing this or if this will go away?
  • dancermandancerman Posts: 220
    That's not good. Your description indicates to me that something inside the drum is loose or improperly installed. I would pull the wheels and look inside the drums for signs of metal to metal contact (such as metal filings or places that are ground down by rubbing contact).
  • I smell anit-freeze inside the cabin of my 2002 Grand Cherokee. I suspect the heater core is leaking. Any info on how to get at it? Like a schematic or drawing showing bolts and parts? It looks pretty buried.
  • Your suspicions are probably correct. I would suggest getting the manual, as that will be no picnic pulling the dash, If that's the case. If you don't smoke, I suggest you start, if you don't drink, I suggest you start. :P 'Cause it is an all day event and usually requires two people. Just to let you know, Ido feel your pain, because I too have been smelling antifreeze in the cockpit of my Nissan Pathfinder. I suspect I will have to pull the dash soon.Good luck!

  • The floor of the front passenger side gets very wet. I am convinced it is connected to the air condlitioning. Any way to fix this yourself? Has anyone else had this problem?
  • tidestertidester Posts: 10,109
    It could be a disconnected air conditioning drain hose. Perhaps a Cherokee owner can tell you how to check and fix. Anyone?

  • a two year old jeep,with a bad heater core??it has happened..,but,your suspicion of the blocked condensation drain might be it as well..
    my advice-if you plan on keeping this jeep for any length of time,and/or fixing stuff yourself-go back to the dealer,and get the body service manual for your model..this is the book written by the people who designed and built it..
    i've worked on a lot of old stuff,ans having the book from the builders is a valuable thing..they can show you how to get to the "secret" bolts they always seem to hide in places i'd normally never think to look..most of those haynes and chilton manuals are so generic,they seldom help when you get up under the dash,and need to find that mystery screw..
    --one other source might be THE LOCAL LIBRARY!!..i once found service manuals for a packard!!..aparently,some old mecanic had donated his collection..they shure were handy!!..try there!!?! :shades:
  • It's probably a disconnected or blocked drain hose as said by Tidester. If no water dripping on the ground after the A/C has been running awhile, then that's the problem. You may try posting this question in one of the GRAND Cherokee threads where more GC owners will see your post and chime in.
  • 1990 Cherokee Classic, 125,000 miles, and when starting, it turns over excessively before finally starting, probably about 5-10 seconds. It doesn't require any mashing of the throttle or anything, it just turns over for a while and then kicks on just as it should, and idles perfectly fine.

    It does this even right after shutting it off, which I think is weird.

    The plugs, wires, and I'm pretty sure distributor are new, and it looks like the PVC system was replaced right before I bought it.

    I have friends with Jeeps and none of them require the length to start. They just fire right up first crank.

    It doesn't worry me TOO much, because it always starts, but it gets extremely annoying.

    Any ideas??
  • two things come to mind..fuel pump pressure,and a stuck/plugged start injetor.
    ---get thee down to the auto zone,and see if your omputer has been throwing out trouble codes..see what they say..mom's shi-vole-t (chebby) cranked till she wore out both the starter and the flywheel starter ring on her 89 baretta,from a clogged start injctor in the trottle body.from running CHEAP AZZED GASOLINE!!..i mean,while you'r pumping,can't you tell the diffrence in the smell of the cheap stuff,and when you put a tank of the good stuff??at $4/gal,is 20 cents per gallon make a difrence??but mine starts better -especially in winter-on marathon premium.asking a old car to run on crappy gas is just BEGGING for trouble..i even seem to get better mileage by using the goods,t balances out for me..it won't do it on one or two tanks,but after three,see if it runs better..also,dump in some octane boost/injector cleaner-YES,THE EXPENSIVE STUFF!!..that 2-for-1-for.99 cents stuff doesn't work as well as the b-12 for 3.50,or the stuff lucas puts out...cleaner will help,but it's not a -rebuilt-injector-in-a-can...if it's broke-fix it..
    --also,with todays cars,especially with something thats giving you trouble.try turning on the key-for at least a -five-count..(turn key on-count to five-out loud if you need to)..this will give the fuel pump a chance to bring the pressure up ,...
    --if this helps,your fuel pump is getting weak,and you should plan on replacing it --SOON--..before you get to do what dyslexic ford drivers do

  • Hello
    Did you ever get an answer to if the steering gear is servicable?
    I have a 98 Grand Cherokee that has a lot of movement in steering wheel when driving.
    I am wanting to find out if this play can be adjusted out.
    If it can, how is it done.
    Thanks
  • I have a similar issue with my 98 Grand Cherokee 4 Liter engine.
    When cold there is 3 possible ways to start.
    1) Let starter motor turn for about 5 or 10 seconds.
    2) Try initial start but only to turn over engine then turn key back and then turn over again, engine then starts up on this second turn of the key.
    3) Turn key to run position, wait 2 seconds and then turn over, engine starts right up.

    Does anyone have advise on what needs to be changed to correct this minor but frustrating issue?
