Hey guys, been tackling an issue with what I thought was my blower motor but turns out to be something further in than that.
Basically fuse 37 blows (feeds only the blower motor)
I've taken the blower off the circuit - keeps blowing fuse 37 (blower not at fault)
Took the relay out - does not blow - no fuse box damage/problems
After all of that I started to replace wiring - i've replaced 3 separate lines (following the AC electrical diagrams out of AllData) - and I suppose I am now at the under the hood issue and I don't want to waste more time or wiring if there is somewhere else I should be looking for this ghost issue
I at one point forgot to splice a wire that feeds into the back of the AC selection switch (max ac, ac, panel, etc) - and the blower ran happily and no blown fuse but I then had no AC compressor cycling (it feeds into this circuit) - fixing that wire brought temporary joy as my compressor kicked in and everything seemed fine - but then of course fuse 37 blew out.
I attached a picture of the electrical diagram and I have basically rewired the entire far left side of the schematic where it feeds into the violet wire on the heater mode switch as well as the violet/orange wire that then runs off the heater mode switch to a junction connector under the driver side dash. Also attaching the photo of the 412-03-00-2 diagram that is the piece of the puzzle I am moving onto - and where I am lost on where I should look/replace first
I'll add that when I hook everything up - the compressor seems to try and cycle but cant fully engage - and after a period of time then fuse 37 will blow...
Any help/guidance is appreciated
