Wide Open Throttle (WOT) A/C Relay
WARNING: This page is about a different car, the 1996 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
Relay is located in power distribution box and is controlled by the Powertrain Control Module (PCM). Under certain conditions (such as engine starting, heavy acceleration, etc.), PCM will signal WOT A/C relay to interrupt power supply to compressor clutch.
