Changing the standard fan resistor behind passenger side dash

vananarama · Mar 21, 2026

On YouTube a few helpful videos make changing the large green resistor which controls the strength of the standard air vents seems to blow every few years (you know when - only 4 works). However with the T6 Cali it’s much harder to get to than these videos for the standard Transporters seem to make out. In short, it’s extremely fiddly and you have to be something of a contortionist to get into the footwell in order to use a ratchet tool effectively.

I’ve just changed it on my 2018 California and I’m very proud of myself, and just wanted to let you all know.

to change the large green resistor which controls the strength of the standard air vents. This resistor corrodes over time and seems to blow every few years (you know when - only 4 works on the air dial).

You also have to remove the glove compartment, which is actually the easy bit.

I fully agree to the difficulties compared to the transporter in videos. I think the very stiff and thick underfelt/board makes it a challenge worth posting about. Well done.
