My Air C/ doesn't function, Brake Light always on and Power Locks do not operate. I supposed that is an electromechanic problem. If any other member with this problem? I need to Fix It!

Sometimes operate properly and sometimes don't operate. Is a very rare problem to fix it.

check all the fuses, then check the grounding if you know how to use a multimeter. If you have access to a multi meter, we can help you out.

sounds like a faulty or poor ground. When I get home I can look through the manaul and see if the same ground operates those circuits. Did all of these all go out or happen at the same time or happened at different times?

All these go out at the same time

well I searched through the manaul and didnt see that any of these were connected in any way. If the brake light stays on at all times, first check to see if you are low on brake fluid. As for the door locks, do they all not operate?

I'm go to my nearest Honda Repair Dealer and the system shows the Fuse Box in the interior of my car has faulty ground. Finally, I changed that and the problem was corrected. The new OEM Fuse Box cost me $254.75 and labor $130.00. Uf!

Damn! That was a weird one. But it WAS a ground.

the under dash fuse box had a faulty ground??? Someone please explain that one to me.

I tried it to say the under dash fuse box was crossed and the dealer replace with a new one.

You know.... I'm still trying to figure out how that could even HAPPEN.
I wonder if the dealer didn't just replace the fusebox for $$$ and move a wire that was the real problem. A fuse box is pretty straight forward.

I was thinking the same thing. I dont understand how a fuse box could have a faulty ground. You have wire harnesses that are connected to the fuse box and run to sensors, relays and other various components. If there was a faulty ground, I would think that a wire would be reattached or maybe one had an open circuit and needed to be soldered. And even looking at the wiring diagram in the manaul doesnt show any ground that is associated with those 3 circuits, or one that connects the 3.

I persoanally feel the dealer did screw you over, or the technician did and saw that there was a simple repair that was needed and wanted to make alot more money. I agree with tinman on that. I would call the dealer and ask them about that.

question: Is possible that the fuse box was crossed? The dealer says that is the cause of the problem

 
Rep Power: 454

I am not sure what that even means. After looking through the manaul, I have located all the grounds that the vehicle uses and those 3 systems do not share the same ground. There are around 15-20 grounds the vehicle uses as many of the systems share the same ground. More then likely if there was a faulty ground, more then those 3 systems would have been out. And I dont see any ground at the fuse box. its just one of those "it seems suspicious" situations.

If the fusebox was crossed, it is clearly a defect in manufacture of that fusebox. The fusebox is a safety device, and should NOT be flawed. If the fusebox itself is indeed flawed and you did nothing to it or touched it, I'd scream like hell to have it replaced as a defect by honda. For all you know it could have caught on fire and killed you. I know that dealers will go to any length to pin any problem on YOU. It's amazing that the lightswitch issue was actually a recall and not blamed on the customer on a case by case basis.

Now, if you modded your car and added anything to the electrical system that could have overheated the fusebox, causing a short, it's your fault.

Well I figured out how this possibly could have happened. After reading though the manaul, I found that the under dash fuse box is the mulitplex control unit. And all 3 of those components go though the control unit and I see how it was possibly to have the faulty fuse box. At the time I didnt know that the control unit was the fuse box.

I guess the tech may have done a series of tests at the control unit and this was found. But it could have also been a way to make money.

My cousin's car has this exact same problem. It happened after the amp and subs were removed, but the aftermarket player is still installed. Brought the car to dealer 2 or 3 times and they still couldn't figure out what the problem was and charged like $200 for fixing nothing. They said her a/c needs a new compressor and that they had to troubleshoot some more at a later date.
Now that I have an idea of what the problem is, should I bring it back to them with this new information? If so, do you think the money already spent on their "troubleshooting" should apply to the fix.
One problem is they are the only Honda dealer here.
