Step on my brake shuts off electrical and turns on door ajar tone
When I step on my brakes in my 94 cherokee the door ajar tone comes on for a second and slowly dies outnand its like it kills the electrical systems. Then if i leave it for a while and i don't touch the brake for a while and get in it will start up for a second and then die off. Just changed cap and rotor button. After it starts the one time it will just click, and sound like its trying to turn over but never does, just keeps winding.
Re: Step on my brake shuts off electrical and turns on...
Im not sure if you have the same problem as i did, but i had a 95 cherokee bought brand new, 2yrs later dash lights would not stay on steady, the door buzzer would go off while you were driving and other elect. issues . long story short wiring harness behind glove box had a pinched wire against the body ,grounding it out here and there. good luck

There is not a single fuse just for the seat belt alarm .
The instrument cluster provides the warning chime function. The instrument cluster uses various inputs to determine when to sound the warning chime. The warning chime sounds if:
the headlamps are left on with the ignition switch in the OFF position and the driver door is ajar.
the key is in the ignition with the ignition switch in the OFF position and the driver door is ajar.
the transaxle is not in the PARK (P) position and the driver door is ajar.
a door is ajar while the ignition switch is in the RUN position.
the safety belts are not fastened and the ignition switch is in the RUN position.
the turn signal is on for more than 3.2 km (2 miles).
the parking brake is engaged and the vehicle is moving more than 5 km/h (3 mph).
the ignition switch is in the RUN position and a secondary air bag warning chime request is received from the restraints control module (RCM).
the ignition switch is in the ON position with the transaxle in the PARK (P) position and the driver door is ajar (Hybrid).
An audible signal is provided to indicate when the turn or hazard signal is on.
Safety Belt Minder Deactivating/Activating
Apply the parking brake before deactivating/activating the belt minder.
Place the gear selector lever in PARK or NEUTRAL (manual transaxle).
Place the ignition switch in the OFF position.
Close all the vehicle doors.
Unbuckle the driver safety belt.
Place the parking lamps/headlamps switch in the OFF position.
Turn the ignition switch to the RUN position. (Do not start the engine.)
Wait until the safety belt warning lamp turns off (approximately 1 to 2 minutes).
NOTE: Steps 3 must be completed within 50 seconds after the safety belt warning indicator turns off. For seating position being disabled, at a moderate speed, buckle then unbuckle the safety belt 9 times, ending with the safety belt in the unbuckled state. After this step, the air bar warning indicator illuminates for 3 seconds.
Within 10 seconds after the air bar warning indicator turns off, at a moderate speed, buckle then unbuckle the safety belt.
This disables the safety belt minder feature for that seating position, if it is currently enabled. As confirmation, the air bar warning indicator flashes 4 times per second for 3 seconds.
This enables the safety belt minder feature for that seating position, if it is currently disabled. As confirmation, the air bag warning indicator flashes 4 times per second for 3 seconds followed by another flash sequence of 4 times per second for 3 seconds.
After confirmation, the deactivation/activation procedure is complete.
it sounds like you may have a door switch going bad or in need to adjustment, the car thinks the door is ajar and then cycles the locks. the hard part may be to figure out which switch is making it act up.
If the turn signal bulbs are the same as the turn signal bulbs it would indicate the brake light on the left is not working. If the brake lights AND the right turn signal come on it could indicate a wire is getting a cross feed from an improper source. If you are comfortable with electrical systems - If you have a tow package you may want to check the wires to the trailer. Otherwise have it checked by an electrical shop.
Jeeps are one of those vehicles that has some PROs and CONs. One big con is the front-end. Its never just one thing, LOL. You need to check out the front-end, thoroughly. Check all the components, check out the ball joints, tie-rod ends, u-joints, shocks, wheel bearings, and brake components. You can also inspect the wheel lug-nuts.
It sounds like your fuse block has gone bad and needs to be replaced. Locate and inspect the fuse box and look for any corrosion that is causing the short which is giving you the electrical problems. Good luck and keep me posted.
Hello and welcome to FIXYA, it sounds like you have two problems, first the door ajar switches in your truck are sticking, and causing the ajar light to remain on, and second the door lock actuator is shorted and getting stuck in the lock position. To repair the switches, obtain a can of brake cleaner and spray the door latch of each door for about 3 to 5 seconds, then open and close the door 10 times to work the cleaner into the switches. To fix the lock problem, you must first pull up on the knob in the door panel to unlock it. Then remove the door panel, and replace the door lock actuator.
the wiring for the dome light, door ajar and radio is most likely crossed with the brake light wires causeing it to turn off power or on when pressing the brakes giving electricity to the lights and then it could be cutting off the power to the radio
