Been having an odd and specific electrical problems. On two occasions in the past week and a half I get in and turn the key and nothing. No lights no crank, seems flat dead. After a few times trying it starts and everything is normal but the clock is reset so it lost power somehow. Today I had a minute to look into it and saw my positive terminal had a bunch of blueish corrosion on it. Cleaned it off and reconnected, is there any chance that this was causing the issue or is that just wishful thinking? No codes and I have no idea how old the battery is. 2000 LC with 144k. Thanks. Also I only have a valet key that unlocks all doors and starts it but does not unlock the glovebox.
