Pusrant to my other thread I think i have determined my rad. fans are only running on low. Before I go and drop the $$ for a new control module can anyone tell me how to test the module or make the fans run on high. Or for that matter can someone tell me what tells them to kick into high. They come one when the a/c is on but on on low and I have never heard them on high and living in Texas it should have happened by now.
Car in question is a 2002 Jetta wagon, 1.8t. Unfortunately I don't think the module on my MKIII is the same so I can't just do a swap test.
If there is an easy way to make them run on high all the time that would also work for now till I can get a new module, provided that is the problem.
