Let me first begin by saying that I first posted this question Vortex forum and got no answer.
At FCP under my 2003 Jetta GLI they have 2 options for the fan control high/ low price with different part numbers. VW products suffer from lots of cooling fan problems and my idea was to buy a new relay removed the top cover and quickly check the power in and out puts from the top w/ out piercing any wire.
Amazon also has a low price module 506K but not the other one.
Here are the part numbers in case you are familiar with this item:
