Question about Mercury Marquis
Check the cooling system, particularly the radiator to make sure it is not partially plugged. Additionally, check the radiator fan for proper operation. If the engine temperature is running way above normal, some of the heat is transferred to the air-conditioning condenser, which causes the air-conditioner to lose efficiency. As for your question about a "limiter" switch, there is a high-pressure switch in the air-conditioning system that cuts the compressor out when the pressure gets too high.
