2003 Ram 3500 HO

I am far from home in the Pacific Northwest with a problem and need to disable the grid heaters. It is raining 24/7 so I am looking for the cleanest/quickest way to disable the heaters.

I found reference to a fuse that controls power to BOTH grid heater relays (solenoids) but I don't know where it is located in my fusebox. (The coils are "hot" via this circuit and the PCM grounds the other side of the relay coils to activate the relays)

Can anyone help with a fuse location?

An alternative is removing the fusible link wire (that feeds the heater relays on the engine block) at the battery terminal, but I don't SEE a separate terminal connected to the battery terminal that can be removed. The terminal has several wires molded into it that cannot be removed, however.

Any help to disable this circuit w/o having to climb into the engine compartment would be most appreciated.

Thanks-

 

There are two heater grid relays located on a single bracket on the right battery tray. Pull both to kill the heater coils.

 

Yep-

I was looking for the fusible link on the WRONG side.

I found it easily on the passenger side and disconnected it.

Cool thanks for the update
