Fuse #26 in the car's fuse box controls the radio and air conditioning (AC) unit. This fuse is typically rated at 15 amps. If this fuse blows, it will cause the radio and AC to stop working.
Here are the steps on how to check and replace the fuse #26:
Remove the fuse box cover. The fuse box is located under the dashboard on the driver's side.
Locate the fuse #26. The fuse box cover will have a diagram that shows the location of each fuse.
Check the fuse. If the fuse is blown, it will look like the metal filament inside the fuse is broken.
Replace the fuse. If the fuse is blown, replace it with a new 15-amp fuse.
Reinstall the fuse box cover.
