Oldsmobile Questions? Ask a Mechanic for Answers ASAP
There could be two relays depending on your vehicle's VIN (see attached graphic) on the relay rail located under the hood, behind the passenger side headlamp.
Both "puller" and "pusher" relays are energized by the onboard computer (ECM) based on signals from engine temperature sensor and A/C panel.
Please let me know if there are any other questions that I can help with.
