Question about 1994 Jeep Grand Cherokee

1 Answer

2004 Jeep Gr Cherokee Laredo: None of my windows will operate, and all of the dome lights stay on while I'm operating the vehicle. Both problems started in unison two days ago. Would this indicate that I need to replace some fuses?

Look in the engine compartment for a fuse block. Find a metal casing 30A fuse. It is actually a thermal circuit braker, test it for continuity, although it is suppose to reset itself, it may be damaged.

On the other hand, if your courtesy lights or interior lights are on, check the dimmer switch, someone may accidentaly turn it on Also check that all door are perfectly shut.

Good Luck!! Don't forget to rate this post!!

    Also check the LockOut switch on the driver's side Windows and Locks Board..

  • colleensterc Jul 18, 2010

    I was able to get the dome lights to turn off. You were right- the control switch somehow got turned on. I checked the power window lock-out button, and it is not engaged. The windows still do not operate. I'm guessing the window regulator has gone out. Would you agree?

    I took a look into the fuse box in the engine compartment. Just doing a visual, I don't notice any damage to 30A, but I was not able to figure out how to get it out of the holding case. Should I still pursue the fuse assessment?

  • Rene J Solis Jul 19, 2010


    Don't mind the 30A circuit breaker, in the same fuse box, look for Fuse #12 50A, this is a large fuse, you shouldn't have any trouble removing it, I am certain it is blown, it is the only fuse in the power window motors circuit. You shold be able to see thru the fuse's clear plastic a wire that joins the two fuse terminals together, if I am right, this wire should be blown (not joining the terminals together. In case you have any doubts, remove another one of same kind and compare them.

    Good Day!!

  • Rene J Solis Jul 19, 2010

    I just thought about this. Instead of messing with the fuse, drive to the autoparts store, ask for the jumbo 50A fuse and ask them to install it for you. They will gladly do it at no charge to you : )

  • Rene J Solis Jul 20, 2010

    I was wondering if your problem got fixed or if you need further assistance : )

  • colleensterc Jul 20, 2010

    Hi- I did as you suggested and inspected the #12 50A fuse. I took it out, even removed the clear plastic cover, and it looks to be in fine shape. The little copper connectors are intact, and it looks like the other jumbo fuses. I'm reluctant to go to an auto parts store and get a replacement fuse when this one appears to be good. Back to the drawing board?

  • Rene J Solis Jul 20, 2010

    Hi Again!!

    This was a tough one!! The good news is that I found the problem. It seems that the driver's door wire harness on this Jeeps has the tendency to brake or pull the wires from the Driver's Control Module connector. The two most common wires that brake or came loose, the Black (-) ground wire and the yel/vio PCI bus wire.

    To fix this problem, just need to pull back the rubber harness cover from the door frame, unplugg connector and repair the wires.

  • colleensterc Jul 21, 2010

    Whew! Thank you for this solution. I will give this a look, but it sounds a bit too involved for my limited knowledge and ability. I may have to take my Jeep into my auto repair with your assessment. I have noticed in the past few weeks a rattling sound coming from the interior fuse box, and I've noticed some sort of exposed connector receptor. Also, I didn't mention to you that the auto door lock switch that is on the same panel as the power window switches stopped working at about the same time as the rattling started. As you say, this may all be related.

  • Rene J Solis Jul 21, 2010

    There you go!! The problem could be that the plug came loose and fell off. Try removing the rubber boot from the door and check it out, If it did, you should be able to plug it back up. Give it a try!!!

  • colleensterc Jul 21, 2010

    I almost threw in the towel, but I perservered and took another look at my problem. I did as you suggested and found the rubber harness on the door frame. I managed to pull it back to reveal all the wires, and low and behold, there was that infamous black ground wire snapped in half! All the other wires appeared intact. I spliced the black one, carefully inserted the harness back into the door frame, and I have all windows operating as well as the auto door lock! Yeah! Who says chicks are helpless with cars? Not this one! Thank you so much for working with me. You guys rock!

1996 jeep grand cherokee no automatic interior lights

1. If you have the light switch in the wrong mode the lights will not operate when you open the door.

2. If the interior lights do not operate at all (ie you cannot switch them on and off manually)then you need to check the fuse for the interior lights.

3. When set to the correct mode, the interior lights will operate from a door operated switch so if the switch has failed the lights will either stay on or not operate at all when you open and close the door. Eventually these door switches fail with repeated use and need to be replaced. (Consider how many times the small door switch has been operated since 1996).

I have a 2004 jeep grand cherokee and none of the windows will work and the over head light will not turn off.all the fuses are still good aswell

if your fuses are good check for voltage at the window motor if that is good your problem is in your circut. if your dome light will not shut off that implies that there is a bad switch.

I have a 2004 Jeep Cherokee and after I've closed the door and am in the vehicle driving my dome lights remain on and the power windows don't work.

I had the same problem with my 2004 Jeep Cherokee and took it to a mechanic. They said that 2 wires had broke in 3 of my doors causing the loss of power in the doors. They fixed it for me, but it was pretty price at around 300 :(

Power windows dont work and dome light stays on

It has to be a broken wire! Initially, I lost the door locks & power to the windows ONLY when the drivers door was open. When I closed the door, the problem went away. Finally, I had the problem all the time. I checked for 12 vdc at the switch in the drivers door and there was NO POWER. In the rubber boot (between the car & door) I found the grey wire (with a pink stripe) was broken internally but the INSULATION WAS NOT!!!
