I have a 2003 Honda Pilot. My ac, heater and defroster do not work. The rear defroster does work. Nothing comes out of the vents even though heat does come through when I driving but not when I'm idling. Any suggestions?

 

welcome the forum. it may be your fan not working, located under the dash, may need to go thru the center counsel to access fan. check to see if the fuse if blown first. if you go to autozone.com you can put in your info and go to repair a vehicle to see the instructions.
