I have a 2002 Honda Civic LX sedan. Interior heat-a/c fan not working. All fuses under-hood and under-dash are good. I changed the fan relay in the under-hood fuse/relay box. (not cheap) I changed the "resistor" near the fan. (even less cheap) Fan still doesn't want to work. I figure out that there is no power to the climate controls on the dash...nothing works! This has officially gone from bad to worse! Is there another fuse that I should look at? Is there a wiring diagram I can follow to find a broken wire? This all started after I changed the oil so is there a related wire harness that I may have bumped while changing the oil or filter? I am stumped. I am handy as hell and can fix lots of things, but electrical gremlins get me every time! I am turning in my man card.
