20mins work :D

[cully]

this has appeared on here before before and I made a note about it, but just to be sure........

as above , remove a/c sensor connection by the o/s headlamp and  bridge 1 and 3 for hi speed fan to come on when a/c sw pressed ( green light comes on? )?? YES and bridge 1 and 2 for low speed fan to come on when a/c sw pressed ( and green light comes on.)..?? YES

disconnect the wires going to the a/c pump ( magnetic clutch? ) are there any other wires to disconnect?? NO only clutch white plug and AC pressure switch

does the ecu make eng use more fuel when a/c is switched on?? YES but only by raising the tick-over to compensate for the extra load of the compressor

 or is it the a/c pump working that makes the engine use more fuel when the a/c is on ( more load so more fuel ) ? AS Above

now I have the courage to check this weekend, and I have only found one round terminal  connector to the fans, which is below the air hose and by the rad on the cars l/h/s........I will be checking that terminal block for verdigree ( green corrosion ) and also removing the front grill and relay covers, by the fans.........just to be sure, and tick another maintenance item off the list.

I presume that if the coolant temp sensor fails, then the fail safe is now redundant??NO it still works the same ie overheat for any reason and the fans come on.........temp sensor system fails and fans come on?? Yes
