The fan on my 2016 Ford Edge doesn't stop when I turn off my car. I took the Fan Control 3 Relay out and the fan stopped. I'm looking for the fan relay replacement and can't find the relay ending in AB. I can find a relay ending in A and a relay ending in B, but no AB. I've called the local parts store and they referred me to a salvage yard. Is there a way for me to know which relay I need?
