I have a 2011 Toyota Sienna XLE with 57k miles. I took the car out today and drove it 94 miles (round trip). I noticed that the A/C wasn't as cold as it usually is. It's 85 degrees and humid here in Chicago. Sometimes it would blow hot air sometimes cold air. I did notice that that the front blower motor has been making noise for a while now. Can that have anything to do with the A/C blowing hot/cold air? Or is the A/C compressor going bad?
