The gross weight of a 1986 Jeep Comanche typically ranges from approximately 4,100 to 4,600 pounds, depending on the specific configuration and options. This includes the weight of the vehicle itself as well as the maximum load it can carry. It's important to check the vehicle's specifications or the owner's manual for the exact gross vehicle weight rating (GVWR) for a particular model.

If the brake lights on a 1988 Jeep Comanche are functioning while the tail lights and dash lights are not, it could indicate a problem with the tail light circuit or the associated fuses. A blown fuse specifically for the tail lights or a bad ground connection could prevent them from lighting up, while the brake light circuit remains operational. Additionally, the issue may stem from a faulty switch or wiring in the tail light assembly. Checking the fuses, grounds, and connections would be a good first step in troubleshooting the problem.

The horn on a 1991 Jeep Comanche is typically located behind the front grille, near the radiator support. It may be mounted on the driver's side or passenger's side, depending on the specific model and configuration. To access it, you might need to remove the grille or reach through the engine compartment. Always refer to the vehicle's service manual for precise location and installation details.

In a 2.5-liter Jeep Comanche, the crankshaft position sensor is typically located on the engine block, near the flywheel or harmonic balancer. It's commonly found on the driver's side, mounted to the engine or the transmission bell housing. To access it, you may need to remove some components, depending on the specific model year and configuration. Always refer to the vehicle's service manual for precise location and installation details.

The horn relay on a 1988 Jeep Comanche is typically located in the engine compartment, mounted on or near the power distribution center. It may also be found near the battery or on the driver's side fender. To identify it, look for a small rectangular relay that is usually labeled. If you're having trouble locating it, consulting the vehicle's service manual can provide specific diagrams and details.

On a 1988 Jeep Comanche, the slave cylinder is located on the transmission, specifically on the bell housing, which is the part that connects the engine to the transmission. It is typically mounted on the driver's side and is accessed from underneath the vehicle. The slave cylinder is part of the hydraulic clutch system, operating to disengage the clutch when the pedal is pressed.

Yes, the 1988 Jeep Comanche typically features a distributor with an ignition control module integrated into it.
