* Broken Window Regulator: This is the most common culprit. The regulator is the mechanism that moves the window up and down. It can break due to age, wear and tear, or a forceful impact. Replacing the regulator involves removing the door panel (sometimes tricky) and installing a new one. Cost: $50-$200+ for the part, plus labor which could be another $50-$150 depending on your mechanic or if you do it yourself.
* Broken Window Motor: The motor drives the regulator. It could be burned out or simply malfunctioning. This is less common than a regulator failure. Cost: Similar to the regulator, $50-$200+ for the part plus labor.
* Wiring Issue: A broken wire, corroded connection, or faulty switch could interrupt the power to the motor. This is often cheaper to fix than a regulator or motor replacement if you can find the break. Cost: Could be as little as a few dollars for a new wire connector or more if significant wiring repair is needed.
* Fuse: Check your fuse box – a blown fuse is an easy, cheap fix. Cost: A few dollars for a replacement fuse.
* Switch Problem: The window switch itself could be faulty. This is less likely, as it usually affects both up and down functions, not just one direction. Cost: $20-$50 for a replacement switch plus labor or a DIY fix.
To diagnose the problem:
1. Check the fuse: This is the easiest and cheapest step. Consult your owner's manual to locate the correct fuse.
2. Listen for the motor: When you press the switch, do you hear any clicking or whirring sound? If not, the motor or wiring might be the issue.
3. Manual Check (if applicable): Some Bronco rear windows might have a manual override. See if you can manually move the window slightly. If so, it's likely a regulator or motor issue.
4. Visual Inspection (advanced): Removing the interior door panel (requires some skill and tools) allows you to visually inspect the motor, regulator, and wiring for any obvious damage.
Cost Summary:
The total cost to fix your rear window could range from a few dollars (new fuse) to several hundred dollars (new regulator and motor plus labor). Replacing the regulator yourself can save significantly on labor costs, but requires mechanical aptitude. If you're not comfortable working on your car yourself, you'll need to factor in the mechanic's labor charge. Get a few quotes from mechanics before committing to repairs.
