I have a 2006 Mustang Convertible. The AC/Heater blower works sometimes and then goes out. Sometimes when I start it, the blower isn't working then it comes on and will work until I cut the car off and later start it and not working. Everything else seem normal, the heat and cold temps are fine and when the fan is working everything is normal. I took it to a garage and they said a resister had melted and some component had corroded. They replaced it and it worked well for about two days...

Air Conditioning works sometimes and sometimes it doesn't
