Impossible to tell from here, but could be a blower going bad + a slow refrigerant leak. Although Iíve never heard a blower make a metal grinding noise like that lol. Iíll PM you my phone number. Youíre more than welcome to come over and Iíll give it a look-see, throw some gauges on there. I know on my TJ, the AC is ice cold, but my blower is slowly dying. So again, you could have coincidental, but separate issues. Iím off the next 2 days, and during the days otherwise...
Also, have you verified that controls switch to foot when prompted?
Also, when defrost is on, do those little side vents that Defoe the windows come on?
Open the hood, run AC. Does the AC clutch spin (middle of the compressor)? If it spins, is it constant or clicking on and off? Or is it stable with just the belt spinning the pulley?
I have a buddy with gauges and all that, but thanks for the offer. If I hit a snag, I may hit you up!
It's not a grinding noise, although I can see how you hear that. It's more of a hissing/breathy noise (sorry that's the best way I can think to describe it) that sometimes stays constant and other times gets higher and lower. It's really weird.
I took the panels off my dash on the drivers side and the glove box off of the passenger side. I can see the arm on the blend door move from the drivers side and everything on the passenger seems to be moving correctly. I plan removing the blend door and inspecting it one of these days when I get the time
Yes, the side vents blow air when defrost is on. All parts of the compressor are spinning and there is no clicking present.
I'm going to take it to my mechanic buddy one of these days when I have down time, I just figured I'd ask for help here to see if I can pinpoint it and save him the time.
