Where is the fuse on a Mercedes Sprinter van heater?

The fuse for the Mercedes Sprinter van heater is typically located in the vehicle's fuse box, which is usually found in the engine compartment or under the dashboard. The specific location may vary depending on the model year and configuration of the Sprinter van.


Locating the Fuse Box


To find the fuse for the Sprinter van heater, you'll first need to locate the vehicle's fuse box. This is usually found in one of the following locations:



  • Engine compartment, often near the battery or on the firewall

  • Under the dashboard, on the driver's side

  • Behind the glove compartment


Consult your owner's manual or the fuse box diagram, which is typically located on the underside of the fuse box cover, to identify the specific fuse for the heater.


Identifying the Heater Fuse


Once you've located the fuse box, look for a fuse labeled "Heater" or something similar. The fuse may also be labeled with the amperage rating, such as "20A" or "30A". If you're unsure which fuse controls the heater, you can use a multimeter to test the fuses and identify the one that powers the heater circuit.


If the heater fuse is blown, replace it with a new fuse of the same amperage rating. Avoid using a fuse with a higher rating, as this could lead to a fire hazard.


Troubleshooting the Heater


If the heater still doesn't work after replacing the fuse, there may be other issues with the heater system, such as a problem with the blower motor, thermostat, or wiring. In this case, it's best to have a qualified mechanic diagnose and repair the issue.
