i just got a very annoying noise coming from the front of the passenger footspace, its like a humming/grinding/screeching noise. it is related to the fan of the climate control i believe because when i shut the CC off, the noise stops. Fan belt possibly?

no codes have signified anything along the parameters for this problem, either.

The blower for the climate system doesn't use a belt. It's a blower wheel directly attached to a motor. Does it blow as much air as it should? If it's the blower or wheel that is bad, it will have to be replaced. The replacement job is a PITA. A bad blower won't set a code. Could it be the rear climate blower perhaps?

That is where the blower is located. Probably a bad blower motor bearing.
