Due to COVID-19 affecting the Diesel industry, some orders may take longer to ship. ZZ Diesel is committed to getting you the parts you need during this time.
If your glow plugs or intake air heater is not working on your Duramax engine, one of the problems could be a blown fuse. This fuse protects the main power circuit to the glow plugs/IAH.
Fuse is mounted under the plastic fuse panel cover in the underhood fuse block mounted on the drivers side fender
