blown cabin fuse
Fun times, probably should've created an account earlier. Anyways here goes, the cabin/room fuse is burning out instantly. Dealership says it's pulling 20-25 amps for a 15 amp fuse, says it's the FF21-67-83Y A that's malfunctioning, S2 door lock timer. Bought one off Ebay, dealership says doesn't work, doesn't give specifics. Buy another one off Ebay from a different seller, dealership says it's still instantly shorting out. Dealership insists it's the module, so either I've bought 2 faulty modules in a row, or something else up. Dealership's pretty insistent it's the module though. So if anyone have any insights or a working one to sell, send a reply or pm.
Thanks.
Thanks.

Thought it might be a line since they were also replacing a motor regulator on the passenger side door, but they've said they rechecked their work and didn't find anything.
They said it's fine with the module disconnected and burns the moment they reconnect it. They've also talked with Mazda who apparently told em to try a new part, which isn't quite possible since it's no longer manufactured so not quite sure what hq was thinking.
They returned the car and said they disconnected the module. Power locks / keyless start is out as expected, gauges are back behaving normal as is the cabin lighting so pretty sure the fuse is back, will double check in the morning. Speakers and majority of the displays in the instrument cluster (temperature sensors, climate control settings, some others) are still offline so I'm assuming they've left some other things unplugged as well.

Fuse was plugged in, started today engine light was on. Went to work, came out for lunch noticed the fuse blown again so it's something else.
Dealership says they'll take another look at it with their rotary specialist as opposed to electrician. Probably hold off on buying till they take another look. Still if anyone's has any insight could be helpful, cars back in my hands till Monday.

Its definitely an electrical issue and not rotary related. Diagnosing electrical issues isn't difficult but you have to be very methodical and check everything. If they are intermittent they can be a PIA to find though. The car has never been wet has it? There are a lot of water flooded cars floating around and they are almost impossible to fix

You should grab an electrical diagram and start looking. It should be downloadable from somewhere on this site.

Don't believe it's ever been in a flood, was fine for 2 years, then took it into the shop for low compression, they placed a new engine, passenger window motor also blew so they redid that as well. Just bit curious both time it started to happen was in the parking garage at work, maybe something got jostled loose going over a bump. Sort of want to take off the passenger door panel and see if there's anything that looks off there.

So, my cabin fuse was blowing like this. Turned out the previous owner had an amp running and the blue wire that signals the car is on to give it juice had come lose from where he tucked it in. (he took the system out before selling it) It was hitting the metal of the trunk and blowing the fuse.

Update I suppose if anyone ever does a search, dealership took another look and assigned a new guy. They said the passenger door light was missing, socket and all and the wire was jury rigged to bypass it which failed. Not quite sure how that happened, though haven't any recollections either way on whether that light ever worked. Either way was a short in the wire, so end up having a spare FF21-67-83Y A from ebay presumably working, and a spare FF14 675 (dealership first said I needed this) also from ebay presumably working if anyone's around Northern Virginia and needs one. Would've had 2 spare FF21s but apparently they lost the first one I brought them. So hopefully ends this giant mess of a saga, well that and the first guy that looked at in the dealership unplugged my radio and they didn't plug it back in, so need to take it back in for that.
