I just changed the right front control arm today and after I was done I noticed a couple of weird things: First, the EVIC thinks the hood is open. Maybe the switch but taken in the context of everything else, maybe not. Probably not. Here are the other issues: The left turn signal flashes fast. It has LEDs with load resistors. I took out the headlight assembly to investigate it, and it went away while I was messing with it, but is back once the assembly was re-installed. I couldn't find any chafed or grounded wires. With the key in ON, engine running or not, The high beams and fog lights are lit up very very faintly. This is new. Maybe not from today with the control arm work, but recent. I changed a burnt out headlight bulb and exchanged with the fogs yesterday. If this condition started then I did not notice. When I turn on the fog lights, the left one does not work, and the left headlight goes out. When I turn on the high beams, the left tone doesn't work. It is not burnt out, I know that because it lights up dim as I explained above. All other bulbs, I tried different ones. It is not the bulbs.
I disconnected the negative battery terminal for a 1/2 hour too. That didn't help.
Is my BCM bad? Anyone have this or anything like it happen?

Two things come to mind:

G100 and G101

If not these grounds it may be you multi function switch on the column.

Thanks. And I forgot to mention the problem is intermittent. It went away and has been absent for a day and a half.

Those are the grounds where my load resistors are grounded. I remade them Sunday to no avail.
