So sometimes when I start the car 2012 RX 450h the A/C will not blow out of any the vents. I can hear the air but can't feel it. When I'm driving it will start to come out the dash vents that it's set on. The garage I took it to said my battery was bad, but I just bought a new one 4 months ago. Would replacing the blower motor do it. Does anyone have any issues like this, I live in Las Vegas so driving without A/C for 10 minutes is not fun. Any productive suggestions would be appreciated thank you.
