Hey guys, so I have an 04' Grand Marquis ultimate edition. The LCM began to go bad and I saw that Dorman had a go-around for the headlight relay, so I bought it and installed it. Now I'm having odd issues that may or may not be related. Every once in a while the battery dies. Like not completly just down to 50%. I go to jump start her and she starts right away and immediately the battery is charged again and works for about 2ish weeks and then its at it again. I've checked the alternator and its charging and when the car is running I'm reading about 14.5ish at the battery terminals. So I'm trying to figure out if its the battery going bad or if something could be shorting out and discharging the battery enough to make it not work?

Another issue just started yesterday, the wipers randomly start. About 5 min. after starting the car they start up and I can't turn them off. Does the wiper stalk go through the LCM since you control high beams and such off it?
