No Power to Tow Package Fuses on a 1999 Ford F-250

Question:

My trailer tow fuses have no power to them, where do they get power from. Thanks

If there is no power to the tow package fuses then it either means that the relays associated with the tow package wiring are bad or missing or that the contacts in the power distribution box for those fuses are not present.

The best way to test a relay is to use a known good one in place of a bad one. If the function starts working then you know that was the issue. We do not carry the relays by themselves so you would need to get them from a Ford dealer.

Fuses and relays get fed power through the battery and alternator. The power is transferred through the power distribution box and fuse panels and on to whatever function is associated with them. Use the vehicle owners manual to determine the locations of all fuses and relays related to the tow package wiring on your 1999 Ford F-250.
