Upgrade seat to active ventilated seat, how?
I am new to this forum. Recently I bought a second-hand E500 of 2004. I like it very much. However later I found the front seats have no ventilation function. Can I upgrade the front seats to be active ventilated seats? How much it will cost at MB dealer? Or can I do it DYI?
Thanks,
John
welcome to the forum. Yes it is possible. It is expensive and most likely the dealership won't do this type of work. They are not in business to retrofit cars but rather to maintain it. Trust me even easy retrofits many don't know how to to it. DYI would be one option though.
Currently looking to retrofit heated/cooled seats from an Infiniti into my Dodge work truck. They'll make hot summers around the orchards much more tolerable.
Plus they look nicer with the multicontour color.

Good luck on the retrofit if you do it and enjoy.
Another area that you may want to research is the control system & wiring. If your vehicle isn't already wired for this option, it may not be feasable to attempt the swap.

FYI, I believe the only ventilated seats for our cars are also drive-dynamic, which is a FANTASTIC feature.
My guess it is will be completely cost prohibitive (several thousand $$$) unless you are able to find some used seats.

ventilated seats exist with and without the drive dynamic feature...the very first thing that one needs is a set of seats that have the ventilated feature as it is freaking expensive to order all parts separately from the dealership (complete foam and leather is different).
for those interested - I have a set of good & used ventilated seats in stock in:
- designo beige nappa leather (2 multicontour seats)
- anthracite napa leather (multicontiur driverside seat)
- regular anthracite leather (multicontour driverside seat)
- regular gray leather (2 multicontour seats and a reat seat for a station)
...all complete with FOLDING rear seats (that have perforated leather) and the regular anthracite leather set with optional heated rear seat...and all suitable for modelyears 2003 & 2004 (the 2005 and up seats are different and have a weight sensing system in the US)
greetingz,
While I was looking for a car, I tested Lexus E350 and was impressed by the ventilation function of the seats. I also tested a 2008 Benz E350 and noticed that the seats are also ventilated. However I ended up 2004 E500 from a private party. I didn't check very carefully for the ventilation function in the front seats. When I got it home, then I found that there is no such function on this car.
I will first look for a used one from salvage yard as Bobsquad7 suggested. Well, it sounds very difficult to DIY, I hope I could find a way to insert a small fan down the seat and blow the air through those tiny holes

Anyway I enjoy this car very much, and thanks again for warm concern and kind information!

greetingz,
Lots of work ahead. The drive dynamic seats are already here. Bought a bunch of extra parts and still plan for the second retrofit to make are I have everything I need.


thanks!!

My conversion was from multicontour seats with heating to drive dynamic seats with heating, ventilating, massage.
The seller of the seats didn't give me all of the plastic covers, wiring harnesses and other parts. Some of the covers broke when he completely disassembled the seats to ship them. All in all I spend about twice as much money in the end because of that. If you think these small plastic covers are cheap, you're wrong. Plus many colors are not available anymore. The seats are in anthrazit gray and some of the covers are in black now. Thanks.
I didn't like the fact that I got nice seats with slight wear in a pile of spare parts. It saved on shipping and I'm thankful but after all I spend more money (about the same as I paid the seller just for the seats and frames which he sold to me separately) in replacing parts that didn't come or were broken than I anticipated. And the few extra $$$ if he would have shipped them fully assembled would have saved time, money and frustration beyond you guy's dreams. That being said, I'm still missing a few parts because I simply cannot locate them in EPC. But that is more of a cosmetic issue right now.
Ok now we got that out of the way. The seats are in and working. It took about 8-10 hours total with some short breaks to remove the old seats, take the old wiring harnesses out, put the new ones in, swap about 15 pins on various wiring harnesses to match the new seat control module with the remaining and new wiring harnesses inside the car and putting everything back together. New pump with wiring harness needed and air reservoir as well as the swap of the upper control unit had to be installed. Everything has to be coded, normalized and the WSS has yet to be calibrated with a special tool. I might build it myself.
I had to buy a ****load of extra parts that I wasn't aware of when I started the whole retrofit project because I thought I have it all already since the car was equipped with multicontour seats. I was mistaken. And locating the right parts when you don't know all the details is hard, despite the fact that I work with WIS, EPC and other tools all the time to help others. Many things were very specific and others obvious in 20/20 hindsight.
This all being said, I'm ready to put the multicontour seats that I removed from the AMG in my E320 and replace the old MBtex artificial leather seats. I'm happy to do the retrofit in CA and surrounding if my help and expertise on that topic is needed. I know what to look for and what parts exactly are needed (though depending on the car). Of course it all depends on what car you have and what year because there lies the devil in the details. Many things were changed over the years. My car is an 2004 E55 and the seats came from a 2006 E55.
