I don't have a diagram but the easiest way to tell is to remove the fuse and see what doesn't work. 17 amps is a big drain maybe you should leave the fuse in and see what gets warm or Hot.

thanks for your reply. Tried that, but difficult to reach into the bowls of the engine bay to check for heat in the wiring. .Removed fuse and all things seems to work ok, but was hoping someone with access to wiring diagram (I cant find one on tinternet) could confirm its a fuse exclusively for the aux heater. cheers john c


Hang tight let mecheck something be right back


Check the engine cooling fan motors there should be 2 One may be jambed or stuck.


Let me know if you have time
