Question about 1995 Jeep Cherokee

6 Answers

1995 Jeep Cherokee Sport 4 DR 4.0 I6

Bottom of the steering column under the key switch. The plastic housing gets extremely hot with the A/C or Heat running especially on high. I have taken the cover off and found that the Red Wire which I assume is the hot wire to the ignition switch. It is just that very hot and discolored. I didn't know if it could be a loose pin connection causing heat buildup or something else. Any thoughts will be greatly appreciated.

    Kinda of lost me there. Can you define Power supply short of bad Battery? I just put a new Battery in 2 months ago.

  • jonelsr Jul 23, 2008

    Well I have 2 answers one being a Power Supply and now the Ignition Switch. I guess I'll wait a little while and see what else is suggested.

    Update: I found that if I start my Jeep and turn the key back counter clockwise just a little. It looses power and dies. I purchased a new Ignition switch assembly and found a good plug from the harness to the Switch at the Junk Yard. I will cut the bad Plug end off, replace it with the end from the junkyard by soldering the wires back together, and use Shrink Tube. My concern now is according to the directions to replace the switch I should disarm the Air Bag. Help. But it does not give guidance on how to do this.

    Thanks to all. I have replace the ignition switch and all went well. I believe that the culprit was the contact area where the key and tumbler assembly made contact in the housing. After replacing the Ignition switch the tumbler assembly was tight and no longer heats up. Thanks again.

Due to the weakness of your A/C, the engine has to work harder, which causes it to overheat more and causes the fans try to dissipate all this heat that causes the wire to be hot.Your A/C is dirty already that can't work properly,due accumulated foreign matter,you better clean the A/C so it will operate normally...

hope this may help;

Hi,

Actually though not normal this should be expected. The reason as drcool299 pointed out is that the current passing through is relatively high especially with the A/C Heater on. The fact that this has heated in the past points to the contacts being cooked. Again as drcool299 pointed out, it is possible that the ignition switch could be repaired. Alternately as Pyrhc has suggested, a replacement might be in order.

However, in addition to either the ignition switch repair or replacement, I would strongly suggest that a relay likewise be wired to take up the load of the A/C Heater. The purpose is to prevent the recurrence of the same problem. Repair presumably, is a stop gap temporary workaround, while replacement would be a repeat of the same problem after some time. Any qualified auto electrician wold be able to do the job using a Bosch 4 terminal 12V relay.

Hope this be of additional help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Hello john,

the idnition switch supplies all the power to your accessories and main engine, as you turn on the ac specially at high fan, it draws more power and the red wire you are talking could be the supply from the battery or the accessory wire to the ac. either way it would heat up due to a poor connection .you can dismantle your ignition switch and maight find the problem there . if there is a spring that holds a small copper contact , you can try to stretch it a little bit in order to increase the contact of the wires. and watch for any melting plastics that could lead to the contact getting lower that it used to be.

if all the contacts are ok then you might have a shortage on your ac system that draws too much current on the wire that is why it is heating up..

please keep me informed how it goes to help you further
..
i hope i was able to solve ur problem

tnx..

    if you are working with a lot of electricals, i would suggest that you remove your battery first, i mean just the wires to your battery..every wire of it...



    then after you are sure that you have reconnect and solder every wire of the ignition switch, then put the wires back on the battery...be sure to connect even the small wires that you take from the poles originally.



    tnx,

I would say that there is a short in the ignition switch that is causing the wire to become hot. Replace the ignition switch nd the problem will go away. Depending on the condition of the wire, you may need to run a new wire also.

    The only way that this wire is going to heat up is because of a short or bad connection. Start by looking for a bad or bare spot in the wire or a loose or corroded connection. If the wire and connections are good then changing the ignition switch should fix the problem. A new switch with keys run approx $15 at any auto parts store.

    In most cases, disconnecting the battery will disarm the airbags. However, to be safe, disarm the airbag by takeing off the cover for the airbag in the center of the steering wheel, and disconnect it. If the connection is under the airbag, you may need to take the airbag loose in order to get to the connection. On some, the connection is a bit further down the column.

The wire getting HOT is due to bad power supply sir.

    but 90% the problem can be with the ignition switch. there is some shorting in the ignition switch.

    this can cause the wire to heat to high temperatures. if this is left unnoticed the wire may even melt. but if the wire melts this can lead to serious damages.

    if ignition switch is not the problem then the source supply is the culprit.

    thank you

    good luck

How do I know if my ignition switch is bad on my 1995 jeep grand cherokee lerado 5.2 liter


The ignition switch does not usually go bad on Grand Cherokees but the ignition key cylinder does and it usually just stop turning, stuck in place. Key cylinder can be removed by taking the steering wheel off to access the little clip that's holding the key cylinder in place, inside the steering column.

1995 jeep grand cherokee. When I turn the key on, the warning chime stays on, a solid tone. I took the chime box out, but the power locks do not work properly.


most likely a short in the ignition cylinder and it's housing, ( were the key goes). if you dont want a new cylinder and housing you may be able to disconnect the connector by the housing. you will have to remove the plastic cover from the steering column.

We have a 1995 jeep cherokee 2 wheel dr 6cyl and the heater will not blow hot air my husband has checked every thing he can think of.


have you checked the heater switch that is located under the hood, and is secured to the heater hose's. This switch will have two hoses connected on one side and two hose's connected on the other side, and is mounted on the side of the valve cover. There is a vacuum line connected at the top that controls the valve open and close function, allowing hot coolant to enter the heater core and provide heat to the interior. This is just one option I thought I would mention.

2000 jeep cherokee sport - the blinkers have gone out. Could it be a fuse or bulbs? - Something simple and inexpensive?


If all went out at once, likely it's the module on the right of the steering column under the dash. Most parts houses can show you where it is. There should also be a fuse. used to be the third up from the bottom on the left row, don't know if they moved it...You can back-probe all the fuses in under five minutes with a test light, without even removing them, so that shouldn't be a problem.
