Hello, a little over a month ago I was driving with my AC on and heard a terrible noise and then a clicking for about 30 seconds after and then nothing. After that I had no blower at all. I finally got around to looking at it today and found a nice chunk of plastic that broke off somewhere in the venting and must’ve jammed my motor. It blew the large 40 amp fuse under the hood but no other hvac fuses. I replaced the fuse and the motor ran again but only on full speed and wouldn’t shut off without pulling fuse. I then replaced and spliced in a new relay/resistor but still having the same issue. I tapped on the relay to see if the contacts welded but got nothing. Where should I look next? Thanks for any advice.
