2003 Discovery 2 SE7
So the other day, I went to switch from heat to AC (Hi to Lo) in my 03 D2 (no rear air), and it was still blowing hot and the compressor wasn’t turning on. I then turned off recirc and I heard a snapping noise, and the fan starts vibrating super loud and starts shaking the whole truck. I can now only run it on speed 1 without it vibrating like crazy. I dropped the glovebox down and had a look inside the assembly through the recirc flap, and saw a plastic piece bouncing around in the assembly. It seems to all still work fine though - the recirc flap still moves fine, and it seems like it still switches between heat and cool just fine (compressor still won’t engage though). Why would this be the case, and how should I go about fixing it?
