When the A/C is on, there appears to be a loud rattling sound coming from the radiator/fan portion of the engine. I also get a burning smell when I floor it if the A/C is on.

Any ideas?

when did you change your air cabin filter?

The sound is most likely be coming from the A/C clutch bearings, which is starting to seize up, hence dragging the A/C belt, causing the burning smell.

If the aux fan is bad or the system is overcharged it will also cause the belt to slip causing a burning smell.

Cabin air filter was changed 2 months ago.

Some hint: Check the compressor mounting,maybe loose or broken brackett.

While driving today with the temp set to cold (not A/C), it gave also off a burning smell for a few minutes.

What kind of burning smell? does it smell like burning wood or leaves with a sharp tang to it? overheated metal? rubber? sweet smell?

It smells like burning wood or leaves with a sharp tang to it.

That is probably coolant burning off the exhaust.

Check it over for coolant leaks.
