Sorry I missed that part, check out this post about the J293 module mk4 Fan Control Module (J293) chart and A/C tips | Ross-Tech Forums
It has a nice checklist of things to go over, the mk5 will be close still
The difference with the Mk5 is that the J293 is controlled digitally via the ECM on that pin T4x/3
Do you have a scan tool that can do output test?
