Cooling Fans

When our 986S (2000) went for its MOT last year, during the emissions test, the car overheated and launched its coolant over the workshop floor. The cooling fans are not coming on.

 

Having jumped the relays, the left/slow does not come on, but left/high speed, right/slow and right/high speed all activated the fans. 
 

The AC does not make the slow speed fans come on, however the AC needs regassing, but we suspect there’s damage to the condensers, so not sure if that will have an impact?

 

Would changing the ballast resistors potentially work or does anyone have any advice to offer? I’ve tried a forum search so if there’s a thread I’ve missed, please point me in the right direction!

Thank you for the reply! The working fans only work when the relays are jumped though, not when the engine is hot and they’re needed.

Then you also need to check for fault codes in the DME. You will need a PIWIS tester or Durametric to do that.

Report any fault codes back here please.
