1. Verify the Fuse:
* Check the correct fuse: First, ensure you're looking at the right fuse. Consult your owner's manual to find the fuse related to the digital cluster and the ventilation system. It's possible you pulled the wrong fuse, or a fuse related to the vent problem also affected the cluster.
* Inspect the fuse visually: Even if the fuse looks okay, it might be blown internally. Replace it with a fuse of the *exact* same amperage rating. Don't go higher; that could cause further damage.
2. Check for Power at the Cluster:
* With the new fuse in place, you need to test for power at the digital cluster connector. This requires a multimeter. You'll need to locate the connector, usually behind the instrument panel. The owner's manual might provide some clues about the connector location, or an online forum dedicated to Chrysler LeBaron might.
* Turn the ignition to the "ON" position (not "Start").
* Test for voltage at the connector's power pins. The exact pins and voltage will depend on your vehicle's wiring diagram (again, the owner's manual or online forums might help). You should see battery voltage (around 12V) at these pins. If no voltage is present, trace the wiring back from the connector to check for breaks or shorts. This may involve removing parts of the dash.
3. Address the Smoking Vent:
The smoking vent is a separate issue, possibly involving a short circuit within the ventilation system. Do not attempt further electrical work until you have addressed this safety hazard. Ignoring this could lead to a fire. The problem might be as simple as debris blocking a fan or a faulty resistor, or something more serious.
4. Examine the Cluster Itself:
* If the power is present at the connector, the problem is likely within the cluster itself. This is the most likely scenario if the fuse wasn't the problem.
* Internal damage: The cluster contains sensitive electronics. Even a power surge from a faulty fuse or the smoking vent could have damaged components.
* Repair or Replace: Repairing a digital cluster usually involves specialized electronics repair skills and equipment. It's often more economical to replace the entire cluster with a used or refurbished unit from a junkyard or online parts supplier. Make sure the replacement cluster is compatible with your vehicle's year and model.
5. Seek Professional Help:
If you're not comfortable working with car electronics, a qualified auto electrician or mechanic is the best option. They have the tools, knowledge, and experience to diagnose and repair the problem safely and efficiently.
In short: The smoking vent needs immediate attention. After addressing that safety issue, systematically check the fuse and the power supply to the digital cluster. If power is present but the cluster is still dead, replacement is most likely the solution.
