Air condition and fan dont work

I just had the same problem. i did alot of researching on the internet. its the power transistor. it takes about 15-20min. to replace. it is located on the passenger side on the firewall. take the panel down, underneath the glovebox. then on the firewall slightly to the left , you will see a plug with 4 wires on it. there are 2 phillips screws to remove. unplug. and then install new part in reverse. you dont have to unplug car battery. and your done. i used a angled screw driver bit with my drill to take screws off. 1 screw is a bit hard to get to if you dont have a angled bit. you can get the part at the honda dealer. my dealer had it in stock. about $70-80.
