We purchased a 09 Crown Vic Police Interceptor at auction and while the car runs very well and was well maintained overall we are having an issue with heating and A/C as well as an engine
According to the OBD sensor tool the engine light code is P0125 which states that the engine coolant
is not heating to temperature.
We have not yet replaced the thermostat
but are hoping that is the problem.
The question is, if our coolant temperature is not high enough (dash temperature gauge reads just below mid range) why do we have very hot heat pouring out of the vents at all times?
1. I can cycle the AC on, and get heat at all levels.
2. I can turn the system on vent or mix with temp turned down to cold and instead of outside cool air I get heat, not warm heat but hot.
3. I can drive around with no heat turned on at all and warmth still radiates.
4. The AC system seems to have been overcharged as the pressure broke the gauges just by hooking 2 recharge kits up
