No power to under hood fuse 44, but fuse is not blown. Several other fuses in same area no power either.

Hi,

I just went through the power distribution schematics and feel nearly as confused as I did when I started. LOL The fuse legend for the under-hood fuse box indicates exactly what you said, fuse 44/liftgate. When I go to the schematics, there is no fuse 44 indicated.

So, I located the actuator for the liftgate. I worked backward from the actuator, and nothing indicates fuse 44, but there are fuses that are 15 amp (unidentified). I went further back and found that power to the 15-amp unidentified fuses is supplied via fuse 66 (stud 2) 30 amp.

I attached a pic of the fuse box and highlighted fuse 66. Check that fuse and see if there is power.

Let me know what you find.

Joe
