  • Can a bad thermostat affect car AC?

    Under most circumstances, a bad thermostat will not have any effect whatsoever on the air conditioning system. A stuck-open thermostat will constantly send coolant through the radiator to cool, meaning that the coolant -- and thus the heater -- may never reach its full operating temperature.

    How does a car AC thermostat work?

    The thermostat is basically a valve between the engine and the radiator. When the coolant in the engine gets too hot, this valve opens, letting it pass to the radiator where it will cool down. If it is not heated, the thermostat stays closed, allowing the coolant to continue circulating inside the block.

    Can a thermostat cause no AC?

    Why is my AC not cooling to the set temperature?

    A clogged filter is often at the root of many performance issues. Blocked condenser: The condenser (the outdoor unit) of an AC needs to be clear on all sides so it can exhaust heat.
