Hi Im David. let me see if theres a fuse you can pull. allow me a minute. thanks.
try pulling the RAP relay in the engine compartment fuse box.
if that doesnt do it. its ok to disconnect the negative battery terminal. then reconnect it and see if they quit blinking.
let me get you a diagram
if you cant find it. disconnect the battery.
i dont understand your hesitance to just disconnect the battery.......
i dont think you're stupid. please do not say that about yourself. i will send you that information
here is the location
in the engine compartment, you have to remove the plastic cover that covers the computer. but there should be an external post to disconnect the cable.
it is under the ECM in the engine compartment on the drivers side. It the black plastic thing beside the relay/fuse box. you have to remove the ECM to access the battery.
i believe it just has clips you press in.
