To find the correct location and fuse:
1. Consult your owner's manual: This is the most reliable source. The manual will have a diagram showing the fuse box layout and identifying which fuse is for the radio.
2. Check the fuse box under the hood: Many vehicles have a fuse box under the hood, often labeled. Look for a diagram on the fuse box cover itself.
3. Check the fuse box inside the vehicle (usually under the dashboard): This is a common location for interior fuses, including the radio fuse. It might be located under the steering column, under the dashboard on the driver's side, or in the glove box. Again, check for a diagram on the cover.
Without knowing the year of your Chevy Tracker, it's impossible to give a precise location. Always refer to your owner's manual first.
