Hey all

 

My Ac fan is not kicking in when I turn the ac on??

 

I got her back this morning finally from the re-build and had her re-gassed and all work fine except the AC fan wont come on? so the pressure in the system starts to get dangerously high, worked dandy before the re-build. So any guesses or common problems I should look for? I had a look at the 10amp fuse in the fuse and relay box on the right hand side of the engine bay and thats all good. There is no relay in the Sub Fan socket?? is this missing I can't remember if it was there before?

 

Anyhow any ideas much appreciated.

 

Cheers

You can use the same relay as the headlights (blue one) to test the sub fan, I'm sure that's the fan that only comes on if the car is seriously overheating, I also didn't have a relay in my sub fan either, so not sure if it's just us ??

Hi mate what is the difference between the rad fan and the sub fan then?

The Z has a push-me-pull-you type arrangement. There's a viscous fan on the engine side and a small fan on the other side.

As a quick test, you could try pulling off the coolant temp sensor to see if the AC/Aux fan is working.

 

This at least will tell you if the fan is able to be powered up.

hey all

 

cheers my viscous fan has been replaced by an electric one and a Howe radiator. I pulled the sensor off and I heard a metalic clicking sound but the fan did not spin, I'm guessing this means the fan is spannered.

Is anything preventing the fan from spinning? Leaves, twigs, birds and badgers could be the culprit :D

I didnt see any badgers mate unless theyre those special pesky teeny ones!

The fan does'nt come on when you turn the aircon on, unless water temp is above 90c if your at standstill or up to about 25mph, then above 25mph it does'nt come on unless water temp is above 105c

 

It should come on when you remove the 2 pin water temp connector though.

thanks mate

 

I pulled off the yellow connector and it did not go. I'll get another one and see what happens

Have you checked its actually connected up properly?

good point

 

I'll give it a once over
