Anybody know of a decent ungrade for the seat coolers on an 07 Expy. Mine don't work too well (never have).

 

I don't know what the issue is with yours, mine work great. . .. just perfect to keep the backside from getting sweaty.

You could easily upgrade though, pull the fan out and look up the specs for it. Then just find a similar model (I assume 12V) that is larger/high cfm. There are many computer fans that are 12V, I used to use them for audio equipment all the time.

 

I think there is a TSB out there for the seat cooling issue. Something about reprograming so the fan runs at a higher speed to cool the seats.

Try here for info,,, https://www.ford-trucks.com/forums/9...led-seats.html

 

I had the TSB preformed to speed up the fans just after it was new. Everything is running, it just doesn't do a very good job of cooling.

 

My new 2010 works about the same as yours. It starts off great then after about 40 minutes it seems to do little or no cooling.

I have to take mine back soon for the first service and will ask them to check this and report back.

 

The ford fans don't work well period. I have had mine adjusted to run at the higher speeds, but as some others have posted after 20 or minutes its doesn't do much. Part of the problem its a fan pulling from below the seat and will pull air at whatever the temperature is at under seat. Other manufacturers have it done right where the cooled/ventilated seat is actually part of the a/c. I guess I should have spent the extra 20k to get them
