To find the correct fuse, you need to:
1. Consult your owner's manual: This is the best place to start. The manual should have a fuse diagram showing the amperage and location of fuses related to the trailer lights and power. Look for fuses labeled "Trailer," "Towing," "Tail Lamps," or similar.
2. Check the fuse box(es): Your 2001 Silverado likely has multiple fuse boxes: one under the hood and one inside the cab (often under the dash). Carefully examine the diagrams inside the fuse box lids. They will show you which fuse controls what.
3. Use a multimeter (optional): If you can't find it using the manual and fuse box diagrams, a multimeter can help. Test the voltage at the trailer connector pins to see which circuit isn't working. Then, trace that circuit back to its fuse. Caution: Be careful when working with electricity. Disconnect the negative battery cable before attempting electrical testing.
Possible Fuse Locations and Circuits:
The fuses might be for the tail lights, turn signals, brake lights, or running lights, as these are commonly connected to the trailer connector. The amperage of the fuse will vary depending on the circuit.
Without knowing your specific Silverado trim and towing package, it's impossible to give a precise answer. The best approach is to carefully consult your owner's manual and check the fuse boxes with their diagrams.
