Honda Legend Electrical Warnings Baffle Owner, Fix Needed

Hey there! I had a similar issue with my 2004 Honda Accord V6 last year. The multiple warning lights and A/C error messages turned out to be related to a faulty cold shut-off valve in the climate control system. When I took it to the garage, they diagnosed it as an electrical issue affecting both the A/C and the instrument cluster. In my case, the valve was completely stuck, which caused the system to send incorrect signals to the car's computer. The mechanic had to replace the valve assembly and recalibrate the electrical system. It was a moderate repair job, not engine-critical but definitely needed fixing to prevent further electrical issues from developing. My suggestion would be to get it checked soon, as electrical problems tend to cascade into bigger issues if left unchecked. These symptoms really sound identical to what I experienced, and the Legend shares many components with other Honda models from that era. Best of luck with the repair!

Hey, thanks for sharing your experience! Sounds exactly like what I'm dealing with. Good to know it was the cold shut-off valve in your case, really helpful info. Do you remember roughly how much you ended up paying for the whole repair? Also, just curious, has everything been working properly since then, or have you noticed any other quirks pop up? Thanks again for the advice! Really reassuring to hear from someone who's dealt with the same problem.

Hey again! Really happy I could help! Just wanted to update you, the repair actually turned out great for me. Since having the cold shut-off valve replaced, all those annoying warning lights completely disappeared. And here's the best part, it didn't cost me anything! The mechanic discovered it was covered under an extended warranty I didn't even know I had. Talk about lucky, right? The A/C has been working perfectly since then, no more error messages or any other weird electrical issues. It's been over a year now, and my Accord's running as smooth as ever. Honestly, it was such a relief when everything got sorted out. Those warning lights were driving me nuts! Quick tip though, make sure they check if there's any warranty coverage before you pay. Sometimes these issues are known problems and might be covered, even on older models. Hope this helps with your decision! Let us know how it turns out with your Legend.

Thanks for the follow-up! I actually just got back from the mechanic today. Took your advice and had them check it out, turns out my issue was a bit different. The technician found a corroded wiring harness that was causing all those warning lights and A/C errors. Pretty frustrating discovery since it cost me $450 for the repair, but at least it's fixed now! The mechanic showed me the damaged parts and explained everything clearly, which was refreshing after my last bad experience. Took about three hours total, but wow, what a difference! The dashboard is finally back to normal, and the A/C is running perfectly. No more unusual warning lights popping up while driving, such a relief! Really appreciate you sharing your experience. Even though my problem turned out to be different, your story gave me the push I needed to get it checked out before it got worse. Sometimes you just need someone else's success story to take action, right? Thanks again for all the help!
