Looks like my fans knackered too!

It spins freely but hasnt come on when the A/C is on
it's not supposed to come on all the time with A/C only if the ambient temperature input is 28*C or above oe the engine temp input 110...if you know which is it's relay remove it and bridge it's contact(30-87) to check the fan or blow with a hair drier on the ambient temp sensor
 
@neilly I do yes! Didnt think of that! Theres a specific "test AC fan" function in outputs isnt there!

@sierrafery ahhh I thought as much but wasn't certain, it's been in the garage which surprisingly is the coolest part of the house!
 
I thought so! Any suggestions?
