Top 10 1994 Jeep Grand Cherokee Questions & Answers

The ignition security on/off is located at the trunk lock. unlock and lock rear gate and the alarm will turn off. My jeep sat in my drive for a month before a jeep tech told me this. It still triggers the security sometimes when I unlock the passenger door with the key and I go straight to the rear gate lock and it shuts off instantly.

I had the same problem with my 94 jeep and i ended up finding out what was causing the problem was the starter relay in the fuse box under hood, i believe its the second or third relay. Try turning the key to the start position and leave it there and poop open ur hood and manuelly start the relay

My 97 Jeep Grand Cherokee was doing the same thing. I changed the TPS ( Throttle Position Sensor) Now it is great goes into overdrive fine. It is really easy to change.

try disconnecting the NEGATIVE cable on the battery for 10-20 minutes. re-connect it. start the vehicle and drive it for a few miles to let the pcm reset. (make sure the key is off and out, just to make sure you don't fry something when you remove the negative-black wire cable!!). don't short it against the positive-red!
make sure the negative connector (on the cable) is isolated from the frame, or it will still be grounded! wrap some plastic around it, or something!
good luck!

Disconnect the battery, Jack the rear up on stable jack stands. use a smaller jack with a piece of wood to stable the load under the tank. You will see 2 band straps under the tank, remove the bolts, only 1 side have bolts, the other side swings down. The hose from the gas cap will have to be disconnected, which can be !!!!! when in-stalling. you can then drop the gas tank down easily with the jack just a bit, enough to reach around to unplug the fuel pump plug, and the gas lines. Once it's removed, the pump has a big screw on ring, take it off and the fuel pump can be pulled out.

Hi, there are a few fuse boxes in the jeep, there is a main one on the driver side, there is another one on the passenger side floor by the bottom of the front passenger door and there is one more under the hood on the passenger side.
Take care

my 93 trail jeep has no door locks and the back hatch lock don't work so what other way is there for me to get my jeep outta theft mode?

I'm having this same issue, I"m the only one who drives the jeep and its just an extra vehicle, really don't want to put that much money into it if I can just manually move the seat to the furthest back setting.
