hello, my name is ***** ***** I will be glad to assist you. please allow me a couple of minutes to gather some basic info.Roy
ok, what is the engine serial number and the code???
there are several heaters for the def system. doubt it is a fuse. possible that a wire breaks at the connector on either side of the heater line. tell him to follow the lines from the def pump out to the doser injector for the def and inspect harness carefully.
as I stated, no. there are not individual fuses for the heaters.
yes, but it would fail all the heaters not just one. you said it had a heater failure. did all 3 fail??
you can have him check all the fuses with a test light or volt meter to confirm but there is a reason the fuse blew if in fact it did. I think you have a heater line issue with a wire broken which is more common
