Here's why this is likely the culprit and what you should do:
* Common Failure Point: Multi-function switches are notorious for wearing out over time, especially in older vehicles like a 2000 Stratus. The constant on/off action takes its toll.
* Symptoms Match: The simultaneous malfunction of wipers and horn strongly suggests a problem within the switch itself, rather than separate issues in the wiper motor, horn relay, or other components.
What you should do:
1. Safety First: Disconnect your battery's negative terminal immediately to prevent further damage or accidental injury. The constantly running wipers could drain your battery quickly.
2. Check the Fuse (But It's Probably Not The Issue): While unlikely to be the root cause given both the wipers and horn are affected, check the fuse for the wipers and horn in your fuse box (consult your owner's manual for locations and ratings). A blown fuse would stop the wipers, but a short in the switch could blow the fuse repeatedly.
3. Replace the Multi-Function Switch: This is the most probable solution. You'll need a new multi-function switch specific to your 2000 Dodge Stratus. You can find these online (e.g., Amazon, eBay, auto parts stores) or at your local auto parts store. Replacing it yourself is possible, but it can be a bit fiddly. It involves removing the steering column shroud and detaching the old switch before installing the new one. You can find instructional videos on YouTube for this specific repair on a 2000 Dodge Stratus.
4. Professional Help: If you're not comfortable working on your car's electrical system, take it to a qualified mechanic. They can diagnose the problem definitively and perform the repair safely and efficiently.
Other (Less Likely) Possibilities:
* Wiring Harness Damage: While less likely to cause both issues simultaneously, damaged wiring in the steering column could be a factor. This would require more extensive electrical diagnostics.
* Body Control Module (BCM) Issue: Although far less common, a faulty BCM could cause this, but it's usually accompanied by other electrical malfunctions.
In summary, the multi-function switch is the most probable culprit. Replace it, and your problems will likely be solved. Remember to disconnect the battery's negative terminal before starting any work!
