Right I'm stumped be trying for weeks to get the fans to work on my car, the cars a 306 hdi estate Y reg with AC, first checked all the fuses, then the relays which look like new g cartier ones, pulled the wiring connection off cleaned it up still nothing. The thing i don't understand I've been looking for the bitron unit under the wheel arch liner and cant find one at all. Tried bridging the connections on the brown plug both 1/2 and 1/3 and the fans didn't budge. Did some late 306's not have a bitron unit maybe controlled by the ecu instead ? Could both fans be dead is there anyway to check ?
