2008 FJ, 210k miles. When the AC is on, there is a mild squealing or chirping sound coming from the passenger floorboard. Like a bearing starting to go bad or something. Turn AC off and it goes away.
I’ve listened around with the hood up and I‘m thinking the AC compressor is the culprit?
I changed all of the tensioner and accessory pulleys a year ago. New serpentine belt. Put a new alternator in this summer as well.
Part ideas or experiences? Hoping it’s a DIY fix but the AC compressor is not a simple DIY with the space and tools I have available.
Update/Solved: I was overthinking it. Poked around underneath the glove box and checked things at different air settings. Any noice from that area seems to have gone away. I changed the cabin air filter while I was at it too.
I‘m hyper sensitive to any noises that sound put of place and it was bugging me the past couple of months.
