Does anyone know which of the four relays in the engine compartment is for the cooling fan on my 93 Ciera? 3300 engine and none of the relays are labled. No help from the owners manual. Any help would be great. Thanks

Welcome to AF!

Its hard to say as they get moved around. 4 relays, two are the same, the other two should be different and I think the fuel pump and AC are the same type/# of relay.

Another way is to follow the wires from the cooling fans to the relay(s), the wires should be the same colors.
