Two months ago I fried my gauge cluster cpu in my03 so I got a 00, 01 replacement.

cluster fried

The problem now is my defroster won't work. I looked in the service manual and realized the 02,03 cluster cpu controls this function.

So rather than get the another cpu and have to send it out to change milage again... I want to know if anyone has an Idea to make it work with possibly using 00, 01 parts

this is out of the manual for the ap1 cluster


any help would be appreciated
