2003 Mercury Grand Marquis
Battery Service
The 2003 Mercury Grand Marquis runs a 4.6L V8 and shares its body-on-frame platform with the Ford Crown Victoria, meaning it requires the same robust Group 65 battery to handle its high cranking demands and extensive electrical accessories. These large sedans often develop battery drain from aging trunk light switches and door ajar sensors that stick. OKC Mobile Auto travels to your home or any parking lot in Oklahoma City to replace the battery on the spot and check for obvious parasitic drain causes.
We carry batteries compatible with the Mercury Grand Marquis and most other makes and models. No need to call a tow truck or sit in a waiting room — we bring the shop to you.
