Here's a breakdown of how to troubleshoot and fix the problem:
Troubleshooting:
1. Check the fuses: Before anything else, check your owner's manual to locate the fuse(s) for the power windows. A blown fuse could be a simple and inexpensive fix.
2. Test the other window switches: Even though you suspect the master switch, try pressing the window buttons on the passenger side doors. If *none* of them work at all (not even their own windows), the problem could be elsewhere (wiring, relay, etc.). If the passenger windows work from *their own* switches (but not from the driver's master switch), the fault is almost certainly in the master switch.
Repair/Replacement:
1. Replace the driver's side master window switch: This is the most probable solution. You can purchase a replacement switch from a local auto parts store (provide your vehicle's information for a precise match) or online retailers. Replacing this switch usually involves removing the door panel (there are many videos on YouTube demonstrating this for your specific year and model of Durango). It's a relatively straightforward DIY repair for someone comfortable with basic automotive tasks.
2. Wiring issues (less likely but possible): If replacing the switch doesn't solve the problem, there might be a break or short in the wiring harness connecting the switches. This requires more advanced troubleshooting and potentially some electrical expertise. You might need a wiring diagram to trace the circuit.
3. Body Control Module (BCM) issues (least likely): In rare cases, a faulty BCM can cause problems with power windows. This is a much more complicated repair, best left to a qualified mechanic.
Before you begin:
* Disconnect the battery negative terminal: This is a crucial safety step to prevent electrical shocks.
* Consult a repair manual: A repair manual specific to your 2003 Dodge Durango will provide detailed instructions and diagrams for removing the door panel and replacing the switch. You can find these online or at auto parts stores.
If you're not comfortable working on your car yourself, take it to a qualified mechanic. They can diagnose the problem accurately and perform the necessary repairs. Mention your findings from the troubleshooting steps to help them efficiently determine the cause.
