I have a 91 Accord 5 sp LX. The heater/AC fan blower was intermittant when turned on - now it is mostly not working at all. The 7.5 fuse (#8) under the steering wheel is OK, as is the 30 amp fuse in the engine compartment. I think there is a relay somewhere which could be bad. Does anybody know where this relay is and how to identify it? Mant thanks Mike Thomas
