yj 4.2 Strange heater noise
Hey guys, I've got an 88 yj l6 4.2 auto. The heat gets nice and hot, always has since i've had it. Also, since i've had it, the when the heat is on i get a constant whining noise. Its kinda high pitched, and gets louder the higher i set the fan. If you can imagine... it sounds like someone going ehhhhhhhhhhhhhhhhhhhhhhhhhh, but obviously sounds mechanical.
Since i dont need my heat anymore for a while i figured i'd yank the fan or whatever i may need to do and get it fixed before summer's end. The noise is pretty loud and very annoying.
Thanks for any help.
