Troubleshooting Power Mirror and Electrical Issues on a 2004 Lexus GX 470
Experiencing electrical issues in your 2004 Lexus GX 470, such as non-responsive side view power mirrors and a clock that resets to 1:00, can be frustrating. Here’s a comprehensive guide to help you troubleshoot these issues effectively.
Step 1: Check the Basics
Before diving deep into technical solutions, ensure you’ve checked the following:
-
Fuses: You mentioned that you checked fuse #65. It's crucial to ensure that it is indeed in good condition. If you haven't already, consider checking other related fuses as well.
-
Battery Health: Although your battery has passed diagnostic tests, if it is 56 months old, it might be on the verge of failure. A weak battery can lead to various electrical issues.
Step 2: Reset the System
A simple reset can sometimes resolve electronic glitches:
-
Disconnect the Battery:
- Use a wrench to disconnect the negative terminal of the battery.
- Let it sit for at least 5 minutes. This allows the system to reset.
- Reconnect the negative terminal securely.
-
Check Functionality: After resetting, check if the power mirrors and clock are functioning correctly.
