Electrical issues can someone help me?

[Jasonk]

I’ve taken my car to the dealer 3 times I’ve replaced the alternator the battery the passenger mirror because it was making the clicking sound and not folding in , the car runs a couple days when I get it back each time then is completely dead when I let it sit over the weekend, the car is a 2013 5.0 rspec. Has anyone else has this problem? And what should I do?

If a double-tap on the remote won't beep the horn to confirm the alarm is armed, then you probably have a bad hood, trunk, or door switch. When the alarm fails to arm because of a switch, the circuit is closed causing high current in the alarm circuit and a battery drain condition that will kill the car in 24-72 hrs depending on battery charge and health. Most common one is the hood. Check for a missing rubber knob on the hood tamper switch. Driver side near the fender about 2/3 the way up toward the windshield from the bumper. Door switches you can test via the interior lights.

See post #2 in this thread for the hood tamper switch location:

Failing that you can do a voltage drop test across various fuses for the PCM, BCM, TCM, etc. to look for parasitic drains.

+1 on the above advice. My 09 4.6 had a missing hood bumper that caused the exact same issue.
