Heater control ground location?
Our Accord has a bad heater control. There's power but no continuity. Can somebody tell me where the ground is? I really hope it's not the wire itself as I really don't want to dig through the harness. Thanks in advance!

G401 is the gound for the heater control "panel"....it is also the ground for many other things so it is a bit strange that more than just the heater control panel is not getting ground to "pin #9" on the connector for it 
Behind the left kick panel, you should see a bolt to the body with a mess of wires connecting to it.

These are some photos of G401. It is above the kick panel; so, it is not necessary to remove the kick panel to see it. You may have to remove the dash under-cover though.

I agree with Poorman212 that it is it is also the ground for many other things so it is a bit strange that it is not more than just the heater control panel with issues.
Further testing is needed. Where is there no continuity (e.g., which wires, power or ground, color of wire(s), etc.)?

The leads of the volt meter should be long enough for you to check continuity from Pin #9 of the connector to the ground bolt (g401). No sure what you were using before, could have been a weak coonection.
Note, the manual HVAC control panel on the 6th gen Accord's will go bad. There are a few write ups on here on "how to repairs".

Okay, so I found the G401 and checked again for continuity, and there was nothing.
Basically what has happened is that it has slowly gone bad. It started out being really flaky and it wouldn't always work, and the lights that were on at that particular moment on the control panel would flicker and we would hear a clicking/snapping sound that went along with the flicker. Then it totally died a few days ago, and what really sucks is that it's stuck on hot air, so always blows hot air even with the dial set to cold. NOT something we want to be stuck with when the summer weather hits!
