Hi guys, owned my grand caravan for about 4 years. Just drove it today with no problems and then my wife jumped in and it wouldn’t start. The K5 fuse is clicking a lot so I swapped it with another and nothing. It then locked me out with the immobilizer so I took off the negative terminal for a few minutes to reset it. Now when I turn on the ignition everything lights up then dims and flickers but the ignition never turns over. Unsure if it’s electrical, computer or starter. Any advice would be appreciated

 

And apparently if I click the lock button now it makes a weird grinding noise from under the hood

 

Start with making sure the battery is good and the cables are tight on both ends. Relays will click on and off like you describe when the power supply is low or intermittent.

You can either charge the battery yourself (trickle charger recommended) or take it to a parts store that does battery testing.
