Heated Seat issue
 

2004 PAC at the dealer for this issue memory mirror problem.

They fixed the sagging dash andsay the mirrors work perfect.

The heated seats used to get pretty warm, now they don't.. as if the high setting does not work. They said they test OK.. that 86 deg. is plenty hot and that is what they read. Sometiomes we have to set them on low first for a few minutes and then high or they don't come on. Even when we do this, it feel like they are on low when set to high.

As for the mirrros, they fall short of their destination every time when we go from setting 1 to 2 and back . I have had it in for this before and they claimed they had to replace the mirrors and they were on back order. They never called me back when they came in.

Anyone have any input on the heated seats?? (Chyrsler Tech?)I have to go there tomrorow to demonstrate the mirror and front end problems and to show them how good the rear seat heater works compared to the fronts.

Thanks
Ramon

Thanks my tech friend. I had seen a TSB for the seats but I thought it was just for thememory seat position for cloth seats. Mine are the leather and I believe the car was a late build, march of 04. I will show it to them tomorrow. Thanks a bunch. Any info on the memory mirrors?? This feature has not worked right since new and it seems to be a common problem with many PAC's

RE: Heated Seat issue
 

the flash is for the same controler that tells the mirrors,seats,heat,and memory what to do.

RE: Heated Seat issue
 

You gotta love those all inclusive boxes. Thanks again. I'll report back when I get the car back.

Hi Chryslertech,
I visited the dealer this morning and when you start questioning how they fix things and even mention a TSB, they balk and claim TSB is the first thing they check. This is the service writer. The tech and I took a ride and I showed him how the mirrors don't return to the correct set postions. He says he will replace the mirrors. I explained to him that the driver mirror was already replaced and did not solve the problem. My guess is he will still replace the mirrors. You woud think that if both mirrors exibit a problem, it's not the mirrors... unles the mirrors were designed wrong.

As for the heated seats, we turned them on for our ride (we were trying to listen for suspension noises that have now disappeard) he said his was really hot, but mine was not. We used to have to turn the seats down to low becasue they got so warm. We don't have to do this anymore. Sometimes though they do get really hot but not that often. He explained that the heat elements get their signal PWM of which I am familiar since I deal with this in my work. The elements must be bad so he will change them, since all other memory funtions work ok for pedals and seat position.

I don't understand why the problem can not be diagnosed and parts are always replaced to solve a problem. He did not seem to think the TSB you gave me will do anything since my seats are leather. I assume the TSB is a re-flash of some sort of which I think he isnot going to do. Is a re-flash such a big deal?? He seems like a nice guy and I am giving him and his writer a chance before I go to the Service manager. This sure can be frusrtating.

Thanks
Ramon

RE: Heated Seat issue
 

alright lets see where to start. If both mirror were defective that would be like a 1 in a 1000 chance and that would be right out of the factory. Both mirrors doing the same thing at the same time haaa NO. As for the PWM yeah that are big deal a bunch of things are controled that way like lights in and out dash stuff signals to and from computers. U should ask the tech were does the PWM come from humm The Heated Seat Moduleis were. where oooo geee thats the flash from the tsb or in simple trems a software update for the computer. To update a computer takes 5 min of work the DRB does the rest no big deal at all I do it all day long,I would rather flash a car instead of replacing a part ne day. Last thing have u ever seen heated seats that were NOT LEATHER?? Not me or atleast not ones that some one asked for from the factory or aftermarket geee some people. Let them do what they want then go back ( sorry ) and get them to flash the HSM.

RE: Heated Seat issue
 

Thanks buddy, maybe they are thinking that the memory problem for the seats is only the non leather seats. Your right, I have never seen a cloth heated seat unless it was added aftermarket. I'll keep on them for the flash. I just hate it when parts are thrown at a problem instead of solving the problem. This is just a flash and not adding a ground strap??

Have you ever seen or heard of the memory mirror problem?? I have seen on other forums that a lot of people have problems with the mirrros... more so than the heated seat, memory seat problem. This has been going on for 3 years and chysler either says there is no problem or says there is no fix. I have taken it to 2 dealers and they claim there is no mirror problems and that mine werk just fine. They seem amazed evertime I show them that they don't work correctly.

RE: Heated Seat issue
 

no there is no ground strap for that computer its inside and self grounded to the body through grounds. U only need a strap when something makes static electricty like moving parts cloth or fluid with acid in them like coolant.I have seen some probs with mirrors but not that many most of them have been the module iself where they dont work at all and other stuff as well.

RE: Heated Seat issue
 

Again, Thanks for all your help here.
The dealer just called and they are going to replace the "All inclusive module". Mine is Rev AA nd the new one is AG. 2 weeks to get it so I will report back after they replace it. Is this plug and play or will they have to flash the new one or is it pre-loaded?? And they say it is one module for both left and right front seats/mirros/ peals, etc. You agree??

Ramon

RE: Heated Seat issue
 

humm wonder why they cant flash it to the ag but yes the HSM controls both seats, mirrors ect and it will be up to date as far as software

RE: Heated Seat issue
 

Ok, thanks for keeping me up to date on how things work.. it's the engineer in me I guess. I'll report back when the repair is complete.

RE: Heated Seat issue
 

Got the car back yesterday. The heated seats seem to work better, I will have to let my wife be the judge, but I had to turn them to low after 15 minutes. They replaced the module with 5082046AG , checked the connector, and flashed the module (TSB 08-012-06). They have different numbers or arrange them differently?? They claimed this would work for my mirror memory problem too but it did not. I read the schemaitcs and it looks like the mirrors are controlled (memory too) by the Driver door and Passenger door modules. It willl have to go back for the mirrors.

RE: Heated Seat issue
 

the mirrors are controled by the door modules yes but not the memory part no. The HSM sends a signal over the bus to the door modules and the door modules then make the mirrors move as such programed.

RE: Heated Seat issue
 

So you are saying the memory portion is handled by the HSM for the mirrors? If you set the mirrors for each person, then recall one position and it only moves half the distance, then recall it again and does not move at all, which part is at fault?? This is how my mirrors work.. since day one for the past 3 years. They perform the same way since the HSM was changed. The driver mirror was changed early on and this did not do anything either. The tech is suggesting replacing both mirrors again but it appears they don't get a signal long enough because they stop short?

Are you sure about this?? At looking at the Service Manual, page 8E-6, it makes it sound like the door module handles the mirror memory. page 8E-12 desribes the HSM and controlling the heated seats, seat memory seat and pedals only.Am Ireading this wrong?? Even the TSB mentions nothing of the mirrors 08-012-06. maybe the wording is confusing in the manual. I don't want to say you are wrong because you do this for a living, it just read different to me.

Thanks

RE: Heated Seat issue
 

he is just giveing the wrong info

RE: Heated Seat issue
 

talk to you latter jerk

RE: Heated Seat issue
 

lets see thats given not giveing and later not not latter i know i have some typos myself but gee why do kids haft to make trouble i guess trying to get a rise out of people is fun or something. U joined what less then 48 hours ago if u spent all the time doing nothing but reading all 831 posts then I would say u dont have much of a life. But like a human I went back and looked at the functions of the Driver door module and saw that yes infact the DDM is the hub for the mirror memory and busses out the info to the PDM and to the HSM for storage for the info. So with that said see if the dealer will replace the DDM for the memory mirror issue sence the heated seats are taken care of thus far.

RE: Heated Seat issue
 

Hey Chryslertech.. can't you ban this person if they are flamming you since you are moderator? I checked that person out to and saw he was bashing you on various threads in about a 10 minute window.

As for the car, I will take it back to the dealer and let them mess with it. I just want to educate myself so I understand what they are doing. They told me I had 12 months or 12k miles if they did not fix it the other day.

Take it easy and thanks for all your help.

Since I am now out of warranty this module now failed completely, except for get this the mirrors will move but not to full postion. We always had the mirror issue and gave up on them ever repairing it. Now the seat are frozen in place with the passenger almost fully reclined. My son reclined when we were in Home Depot. Would you venture to say what this repair could cost or since we took the vehicle in so many times for the mirrors that Chrysler might repair for free.
04 Pacifica had extended warranty to 75000 and now has 88,000

This is our only complaint about the car. Wish they still made them. Doesn't make since that everyone copied this car and and then it was no longer made.
