Many 2003 CRV owners have experienced issues with their power windows. The windows may become slow to operate, stop working altogether, or get stuck in either the up or down position.

What's causing the window woes?

  • Faulty window motor: The electric motor that powers the window can wear out over time.
  • Broken window regulator: The regulator is the mechanism that lifts and lowers the window. If it breaks, the window will no longer function.
  • Dirty or damaged window tracks: Debris and grime can accumulate in the window tracks, causing friction and preventing the window from moving smoothly.

How to fix it: Start by cleaning the window tracks with a silicone lubricant. If that doesn't work, you may need to replace the window motor or regulator. These components are relatively inexpensive and can be replaced by a DIYer with some mechanical experience.

4. Oxygen Sensor Failure: A Check Engine Light Nightmare

A malfunctioning oxygen sensor is a common cause of the "Check Engine" light illuminating in the 2003 CRV. Oxygen sensors monitor the amount of oxygen in the exhaust stream and provide feedback to the engine control unit (ECU) to optimize fuel efficiency and reduce emissions.

Why do oxygen sensors fail? Oxygen sensors are exposed to high temperatures and exhaust gases, which can cause them to degrade over time. They can also be damaged by contaminants in the fuel or exhaust.

Symptoms of a faulty oxygen sensor:

  • Illuminated "Check Engine" light.
  • Reduced fuel economy.
  • Rough idling.
  • Poor acceleration.

What to do: A diagnostic scan tool can identify which oxygen sensor is failing. Replacing the faulty sensor is usually a straightforward repair. It's recommended to replace oxygen sensors in pairs (e.g., both upstream sensors) to ensure optimal performance.

5. Ignition Switch Issues: Key Problems

Some 2003 CRV owners have reported problems with the ignition switch. This can manifest as difficulty starting the vehicle, or the key getting stuck in the ignition.

Why is this happening? Wear and tear on the internal components of the ignition switch is the most common cause. The switch contains delicate electrical contacts that can become corroded or damaged over time.

What are the signs?

  • Difficulty turning the key in the ignition.
  • The key getting stuck in the ignition.
  • The engine not starting, even though the battery is good.
  • The starter engaging intermittently.

The fix: Replacing the ignition switch is usually the best solution. This is a more complex repair that may require professional assistance, as it involves disconnecting the steering column and airbag system.

6. Catalytic Converter Problems: Emission Issues

The catalytic converter is an important component of the emissions control system. It converts harmful pollutants in the exhaust gases into less harmful substances. Over time, the catalytic converter can become clogged or damaged, leading to reduced engine performance and emissions problems.

Why does it fail?

  • Age: The catalytic converter has a limited lifespan.
  • Contamination: Oil leaks, coolant leaks, or other contaminants can damage the converter.
  • Engine problems: Misfires or other engine problems can overheat and damage the converter.

What are the symptoms?

  • Illuminated "Check Engine" light.
