Welcome to AF. Coolant temp sender or temp sending unit? Fans are controlled by a relay.

Remember they only work at above 225 degrees, you will need a scanner to check the operating temps. The coolant temp sensor or the ac pressures trigger the relay, what makes you think they do not work? You have not diagnosed the problem at all if in fact you have one, again what is the problem?

the fans are suposed to to come on 225 & 232 BUT only ac fan on front of comdenser not the radiator fan replaced both relays checked temp went to 260 does temp switch send message to relay to kick fan on if does do you know where it is located thanks for helping
