Gents I suspect I have a fan gone and would like to locate the 3 relays that control the two radiator fans. The Haynes manual for the 406 shows these in the wiring diagram but gives no information on their location. The wiring diagram also shows a test point between the fans when used in series i.e. low speed) where is this located. Mike
cooling fan relays should be located in the fan shroud or the side of the radiator the test point is not far from them follow wire from LH cooling fan your find it
I have now located the 3 fan control relays behind a cover, after you remove the radiator grill. I thought the relays were used to provide either the fans in series for slow speed or parallel for fast speed as per Haynes manual. I am not so sure without a wiring diagram for the 406 1.9 TD GLX with air con. I have put 12v across each relay coil and they all test OK with about 1 Ohm contact resistance and the contacts change over as required so no problems there. I also have 12 v at each of the fan relay c/o contacts. I expected to test a resistance from the other c/o contact via the fan to earth this however is not the case
1 are the fan motors normal brush DC motors? My passenger fan only seems to work. 2 Can any one supply a wiring diagram orMotorsForum website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
