Mode and A/C buttons light not working in accord 1998
 

Hello to you all in HAF, My A/C and Mode buttons light did not come up when the ignition key is on. Also there is no way i can make use of the A/C. Also i notice a burning smell coming out from the vents the one located on top of the temperature control dial. When i touched the control dial it appears hot. I am thinking something is burning inside. We have checked for blow out fuse but all appears normal.. What do you suggest might be the problem for the light not coming up and the burning smell from the vent. i will be glad if i can get a quick response. Mileage is now 320,000. 4cyl. Auto transmission. Hoping to hear from you all soon. Thanks and God bless
