On average, the cost for a Hummer H3T Fog Light Relay Replacement is $119 with $24 for parts and $95 for labor. Prices may vary depending on your location.
Your fog lights don’t need to be on if the headlights aren’t on. For that reason, a fog light relay is used. The fog light relay acts as a switch, enabling the fog lights to come on only when certain criteria are satisfied. Typically, fog lights do not come on when the high beam headlights are on either. The relay directs power to the fog lights only when the switch is on and the right lighting circuits are on. The use of a relay means a low voltage fog light switch can be used. If the full voltage of the fog lights runs through a switch, the switch will become very hot and overload.
Fog light operation is checked when regular maintenance inspections are performed. If the fog lights aren’t working, have them diagnosed and repaired by one of our expert mechanics.
All lights are required to operate as designed for a vehicle safety inspection. Not only will your vehicle not pass the inspection if the fog lights aren’t working, but your night vision will be obstructed. Have the fog light relay replaced as soon as it is deemed faulty.
