It is more than a simple switching relay – it is a small control unit for the air conditioning system: it switches the magnetic clutch of the A\/C compressor while monitoring drive belt slip via a speed comparison between the compressor and engine, protecting the belt and compressor. It also switches off the compressor if the coolant temperature is too high or under full load\/kickdown, and delays switch-on after the engine starts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation location:\u003c\/strong\u003e In the relay\/electronics compartment in the engine bay behind the starter battery, next to the fuel pump relay.\u003c\/p\u003e\n\n\u003ch3 style=\"margin:22px 0 8px;\"\u003eHow can you tell an A\/C relay is defective?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe A\/C compressor no longer engages even though the refrigerant and electrics are fine\u003c\/li\u003e\n\u003cli\u003eDrive belt and compressor protection via speed comparison no longer works\u003c\/li\u003e\n\u003cli\u003eShutoff at excessive coolant temperature or under full load\/kickdown no longer occurs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"margin:22px 0 8px;\"\u003eCompatible vehicles\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eE-Class W124 \/ S124 (six-cylinder with air conditioning, approx. 1986–1992):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e260 E\u003c\/li\u003e\n\u003cli\u003e260 E 4matic\u003c\/li\u003e\n\u003cli\u003e300 E\u003c\/li\u003e\n\u003cli\u003e300 E 4matic\u003c\/li\u003e\n\u003cli\u003e300 CE\u003c\/li\u003e\n\u003cli\u003e300 TE\u003c\/li\u003e\n\u003cli\u003e300 TE 4matic\u003c\/li\u003e\n\u003cli\u003e300 D\u003c\/li\u003e\n\u003cli\u003e300 D 4matic\u003c\/li\u003e\n\u003cli\u003e300 TD\u003c\/li\u003e\n\u003cli\u003e300 Turbo D\u003c\/li\u003e\n\u003cli\u003e300 Turbo D 4matic\u003c\/li\u003e\n\u003cli\u003e300 T Turbo D\u003c\/li\u003e\n\u003cli\u003e300 T Turbo D 4matic\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e190 series W201 (approx. 1987–1993):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eE 2.6\u003c\/li\u003e\n\u003cli\u003e2.6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eS-Class W126 (approx. 1989–1991):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e260 SE\u003c\/li\u003e\n\u003cli\u003e300 SE, SEL\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe relay carries the genuine part number A 002 545 13 05 (also written 0025451305 or 002 545 13 05).
