2007sedan

Hello everyone!! this is my first post. Today I start my car my 2007 Accord V6 engine run everything is fine but when i step on my brake to put it into gear "Automatic" it locks! So I stick my other key into the unlocked shift hole to put it into drive. However, my instrument cluster is dead "blacked out", AC, Power Windows, Signal "but harzard works", moon roof, wind shield wipers, all of it does not work. So I checked fuses under the hood and the driver side nothing is blown. So I'm thinking it might be the relay. If it is do you guys know which one? and I have not done anything to the car since i put HID in about 8 months ago. Please help me!!!! Thank you in advance guys!!!!.

How strong is your battery? A weak battery can cause all kinds of comunication errors between components and the MICU (multiplex integrated control unit). There is a way to get the error codes, but it's complicated without the Honda dealership computer. Check your battery first. Just because it starts the engine, doesn't mean it's strong enough. Autozone usually has a good battery tester.

Thank you for replying, I pretty sure my battery is still pretty good but I will def. go to Autozone this weekend to let them test my battery out.

Like i expected, it was the relays under the driver side dashboard but i didn't know which one it was, and another one under the hood. Luckily my buddy gf works at an auto shop, her boss diagnosed it for me and fixed it with no charge. However, if he did diagnosed alone will cost me 95$ plus 2 relays on driver's side kick panel and one under the hood. Each relay is about 17 to 20 bucks. So I saved about 160 bucks from this. But yes it was the relays but my buddy's boss didn't tell me which one.
