as above noticed when sat in a little traffic the tempture was on the way up and no fans comming in . i got the car home and have checked the fuse and that is fine so i let it run on the drive to see if they would work and still no . what else can i check or could it be that is causing the problem

 

Better off rewiring them like this..........

 

might be worth changing your rad temp sender,it mightened be sending a signal to the fans ,try sticking a permanent live on for a sec see if the fans come on

 

Bridge the connection on the connector for the switch on the bottom of the rad.

If the fans come on its the switch, if they dont then its something else

 

as above, pull plug off rad temp switch, bridge terminals with split pin (or wire)
if they work, temp sender,
if not, check fuse in fusebox, see if its melted the fusebox! very common!
