* Turn Signal Flashers: These are typically *not* a separate, easily accessible flasher unit like in older cars. The turn signal flasher function is usually integrated into the body control module (BCM) or a similar electronic control unit. You won't find a separate flasher unit to replace. Problems usually require diagnostics and potentially BCM replacement or repair.
* Hazard Light Flasher: This *might* be a separate unit, but it's less common than in older vehicles. It could be located in the fuse box under the hood or, less likely, inside the dashboard. Check your owner's manual or a wiring diagram for your specific vehicle. If you have a separate hazard light flasher, it might be a small black box-like component within the fuse box.
In short: Don't expect to find a readily accessible flasher unit like in older cars. For troubleshooting, you'll likely need to consult a wiring diagram or a repair manual specific to your 2000 Dodge 1500. The problem is much more likely to be a faulty BCM, wiring issue, or a bad bulb/socket.
