Multiple Issues?

[MzDax]

Hi everyone,

Before I decide to take this in to a dealer or shop I'm having multiple electrical issues and hope someone has some suggestion. I've search the forum but nothing really close to whats happening. I have an '07 Mazda 3 currently I'm unable to unlock/lock the car using the two key fobs and that could be because the Door Ajar light on.

I've checked all doors and trunk all closed fine. Also as I turn the car on all the needles reset to full and drop back. The lights inside the car reading lights, remain off can't turn them on. I've reset the battery to clear the ECU and now the radio won't turn on but still have the Door Ajar light on and still all lights remain off.

What could be the issue here? is it a bad fuse somewhere, is the battery bad? If anyone has come across this or has any suggestions let me know. :bang

Thanks.

If the car starts fine then chances are its not the battery. With the symptoms you describe I would put my money on a bad ground. Check all the main grounding points see if there's any corrosion or if their loose.

Thanks, I checked and remove all the fuses of issues in question and none were burned out but once I put them all back in problems went away so seems to be one of them most of gotten lose.

sounds like a room fuse problem under the hood in the fuse box. Glad its working with your reset though. Could be a sign of the PJB aka body control module going bad

any passengers kick the footwell? if they have first (slap them) then check if the fuse box under the footwell. A connection might of come loose, even if it looks like its fully in place. many people who put a cabin air filter in will have this problem after installing it. including me. NOTHING worked after i put mine in but the car still drove. just not fobs, wipers, turns signals, etc. push the cables in the seat of the box and flip the lock.
