Okay, so I know from reading around that these things barely do anything... So I put on some boxers and went out to my car at night and drove around with them on and I didn't feel anything but my sack sticking to my leg... Both sides don't appear to do anything other than cast a blue hue onto my shifter. Is it possible that there's a fuse blown? If so, where is the fuse located? Front SAM?

Best way to check if they are working is to put a plastic bag or better some saran wrap on the seat and see if it "inflates" or moves...

Okay, so my ball sack in basketball shorts is not a good check system. Check.

You could pull the cover off the seatbacks quite easily to visually confirm the fans are spinning.

There is a thread here about adding aftermarket fans to improve flow. I bought the fans but haven't done the swap yet. My fans spin but are almost undetectable...common complaint. New (upgraded) fans are reported to make a huge difference.

I noticed your state didn't have the Grand Canyon in it.... therefore you probably wouldn't be willing to do for me the things that ball sacks in basketball shorts would be willing to do.... okay, so that was ultra gay.... Anyhow, I have no mechanical know how unless it comes to GM old school cars or early bikes.... Anyhow, I just want a slight breeze up my crack.... Please? Oh hell, don't take that how it wasn't meant to be taken...

Some of us took it upon themselves to fix them:

I'm not sure if mine are the same in the SL, but I can hear the fan to the active seats running after shutdown prior to opening a door. I can only imagine they were designed to minimize shrivel factor during long drives on the autobahn considering German Climate. Not so effective in zonnie heat.
