Default Turn Signal Fuse blows when A/C is turned on

Car is an '05 Neon SXT

Started happening a few days back. Fuse for the turn signals/hazard lights will blow when used while A/C is running. Haven't checked if it's specifically when the compressor or dash fans are running, but I got a feeling it's some connection with the fans possibly? I don't have a wiring guide on hand so I'm not 100% sure on that.

Parking lights still work, however, but using the turn signal does nothing at all, same with using the hazard light button. I've replaced the fuse a few times already and the same thing happens, even cleaned the entire fuse box as best as I could.

Does anyone got a clue as to what could be causing this? All I can imagine is some short or bad ground in the wiring somewhere, but nothing I could find in the engine bay. (also if anyone has a wiring diagram I'd appreciate it)

Update:

Sacrificed one of my spare 15 amp fuses and it turns out the blower motor for the A/C is what causes it to blow when turned on. I'm gonna check all the grounds again once I get the chance.

Found the problem! Took the steering column plastics off and saw one of the two little black wires that connect up to the turn signal stalk looked bent a bit too much, like a kink in the wire. Straightened it out a bit and cleaned all the connectors with some good ol' alcohol. Works perfect now.

Not sure why I was thinking it was some weird thing with the A/C, just noticed it only happened when I had it on? Maybe some weird coincidence aha.
