New user here! Sorry if i made mistakes with rules or something. Admins remove if so.

​​​​2005 Honda Accord Eu model decided to start doing some weird stuff. Car was standing in the parking lot and suddenly it started to flicker its lights rapidly. Does this in uneven sequenses. ( front and rear lights). Green key light flashing on the dash. Some relay clicking rapidly but it does it at the same time as the lights flicker so its probably the relay for lights... When you put the lights switch into "ON" the lights stop flickering. Lights flicker even if the key is not in the car and doors are locked. Engine cranks but does not start with either of the keys. Radio does weird stuff also. Took the negative terminal off for an hour and after connecting it again, same thing happens. Immobiliser problem maybe? Cars interior is little moist so that could have something to do with this... Anyone has had same kind of problems? Help!

 

Could just be a bad car battery.

 

Forgot to mention in original post. Battery is 4months old and terminals are not corroded so that can be ruled out.

 

Failed MICU especially if the interior is damp.

 

Solved! I used some moisture absorbers and left them in the car for few days. Car works normaly now. There probably was some moisture in place where it isnt supposed to be and caused this.
