How To Add Heated/Ventelated seats and Heated Wheel to Express/Tradesman

Adding Heated/Ventelated seats and Heated Wheel to Express/Tradesman

Theoretically the Comfort Seat and Wheel module under the drivers seat would allow the wheel to work but nobody has tried to just hook that combination up yet. There are 5 additional wires that run from the module over to the passengers seat. If those are not hooked up, it may not work.

Also as far as I know, nobody has got this to work without the full RA4 conversion. 69mach1 has a RA4 with the RA2 bezel and controls and his seats are still not working correctly. We don't know exactly what the problem is but 00R/T encountered the same problem until he did the full RA4 conversion.

I haven't done the ra4 upgrade yet. I did just buy the drivers seat & rear seat from a wrecked truck. Passenger seat was toast unfortunately but getting those shipped to me for $600. Will the drivers seat give me what I need to make the heated wheel option work? I know I have wiring to deal with as well to make it work.

All of the modules are mounted to the bottom of the driver's seat so it may work without the passenger seat. There are five wires that run from the driver seat to the passenger seat to a make it work

Doc-- there's no wires that actually go to the BCM. 2 wires go to the can bus, 2 go to the heated steering wheel, and 5 goes to the passenger side. The 5 passenger lines are vent feed, vent return, heated seat temp sense, heated sensor return, heater control.

Exactly what he said........ I am not sure because I have never tried it but I don't see why the driver's seat would not work without being connected to the passenger seat as long as it was hooked up to the CAN and had the proper power to the modules and possibly the codes added. It would kind of be along the same lines of the heated seats working even when the heated steering wheel is not connected. I guess a quick and easy way to check would be to disconnect the passenger seat and see if the driver seat still works. Maybe I will give that a try this weekend just to see what happens.

Correct. CAN uses a bus topology so by definition there is no "loop". Like you mentioned there is the temp sense feedback to the module for temperature regulation, but it has nothing to do with the CAN bus.

The only reason would be that the CSWM software gets unhappy that there's no passenger seat and decides to disable the driver's too. There's no technical reason it wouldn't work.

you can run the driver without the passenger, but you must watch for the Can loop, there is a temp feed and a line return that go to the BCM via the drivers seat. Now normally these is a circle between the two seats and then the back heated can tie in as well. YOu need to make sure that can bus wires still make a circle or you will never get signals back to the computer. all the wires that go to the drivers side and back again are the can temp and return, as in low heat, hi heat and return and then you have i t hink 3 others as Deer Guy said. Does anyone have the seat to seat schematic? i know its on techauthority.com. i can look when i get home.

Funny I see BCM!

my point was the vent seat temp sense and heated sensor return are in a circle and they are a closed end loop. i didn't use the damn word BCM one time in my post. i was trying to express that there are wires that go between the seats, even without the seat there, you must complete the circuit.



Jesus already - i did my seats 2 years ago when all of you were just kicking around if it could be done and how. Don't put words in my post that aren't there and act like what i was saying wasn't correct.

Are you high?

"there is a temp feed and a line return that go to the BCM via the drivers seat"

Did somebody sneak on to your account and stick that in there after you typed it?

I have a strange feeling that "did my Seats 2 years ago" means you wrote a check to somebody who actually understood how they work. Either way, it's really awesome that people have been trying to get this to work for a while and instead of sharing and helping, you said nothing. It's pretty obvious that you're only here to take and not give anything, so I have no use for you.

Also, for somebody who is wrong as often as you are you really need to learn how to be corrected without acting like a child.

Ok, good for you Deer Guy- i hope as supporting vendor you get a bonus for poking out my short-hand answer. The wires don't RUN to the BCM - duh, that is the part of the loop, but they send a signal to it thru the system and need to be completed. HAHAHA, you got such a good laugh, you are a freaking riot.

Congrats dude, i never thought a supporting vendor to be a jerk til today.

Except they don't. The temp sensor circuits for each seat are isolated circuits that are monitored by the CSWM and used internally for logic. You're wrong. Again. Get over it.

ok, 00, i have had enough of you too, i went to this forum 2 years ago for help and since then all i have done is help people with their installs. No one here could help me and i had to learn it myself.

SO **** off as to your write a check to someone. I am right back to where i was, no one on this forum can help me do anything i havent already done and now that You caught up to where i already was and found this new AE tool, you think you are Gods Gift to MOPAR, well good for you. Be that way, you can do what you want and i will keep helping people the right way, the OEM way where you dont do just what is needed to get the job done, you do it all.

Please post a link to your thread/posts where you've provided assistance and I'll retract my previous statements.

You don't need to link to the thread where you mention giving your dealer $2k for proximity entry parts and labor and being pissed because they couldn't make it work. I already read that one.

i am happy to keep helping those who get sent to me.

Ahh, there it is. After you talking up Seats 'N Such the other day it all makes sense. Does he give you the commission or is it the other way around?

 

[00R/T]

oh, and to correct 00, when i help all these people, it isn't on this forum where its treated like highschool facebook. Hopefully to dear God the people i help will never have to endure this nonsense which is why they were sent to me and i pick up a telephone- you know a land line- and i call them and help them or i email them direct. I don't need to shout out to the world when i do something good like you.

It's also hard to charge people for help you provide on a forum. Keep on keeping on, Robinhood.
