1989 Mercury Grand Marquis OBD connector location
I recently bought my 89 grand marquis, and I have issues with heating inside. I have a feeling the thermostat has been removed from my car, but I would like to check the engine temps with OBD first before tearing it apart. The issue is that I cannot find it. Actron manual points to left fender skirt, clymer manual points to passenger side fender by strut cover, but I just cannot find it. Please advise.
