Can a bad thermostat cause your battery to go dead and ac blow hot air And what other negative effects can a bad thermostat have on your vehicle?

I've actually heard a bad thermostat can cause the evaporator core to malfunction.I've also heard of some a/c compressors will shut off if the engine temp gets to high which could be a thermostat issue. No, the thermostat has no effect on the battery or on the A/C. A thermostat either works correctly or it will stick open or stick closed. Sticking open will cause the engine to never reach full operating temperature, and as such your heater will not work properly. A thermostat stuck closed will cause the engine to overheat.

Why is your 1996 Dodge Caravan overheating?

The Mercury Villager and Nissan Quest are basically the same vehicle. The radiator is cooled by an electric fan and thermostat. If either of these are malfuntioning, that could be the cause. Otherwise, all of the normal things such as low coolant, bad water pump, clogged radiator, bad radiator hoses, bad thermostat,and incorrect timing could all cause the engine to overheat.
