MY 1999 mustang convertible is killing the battery overnight, bought a new battery. Worked for a day then needed to be charged to get started. I took the car to toyota tampa bay they supposely repaired but it did the same thing once I had it at home. Got anothr jump and returned to toyota. Know I was told about a modular under the dashboard is wasting battery. What is a modular?
