It's really late and i just went through the day from hell so i'll explain basically what happened. Brought my car to a custom shop to swap interiors with one of the owners who was returning his lease. Spent a long day there, when it was getting late it was brought to my attention that since my seats were from an 07 (memory) and his were an 05 (no memory) that the cushion and seat back needed to be swapped from the frame of my seats to his. They completed the passenger side and for whatever reason (probably since it was getting late) put the entire 05 drivers seat assembly into mine. Started back and i noticed that my navi, speedo, tach, and odometer were all non functional. Said whatever, i'll figure it out tomorrow its probably something little, and drove halfway home. stopped to **** (60 miles from my house) and restarted the car and it just died. then it cranked for a few seconds but did nothing. tried again and it started for a second and shut off. after that it would only crank. check fuse for fuel pump and it was good, didn't have the chart for all the relays to check. long story short, i had to have the car towed away, going to the dealer in the AM, and i am wondering if the "slight modification" (exact quote) was something like a jumper to the seats to give them power cause they weren't getting power and couldn't figure out why.
anyone have any thoughts on this, i'm hoping that everything will work out but i'm kinda freaking out and trying to stay calm at the same time. thanks

sounds like the shop owes you some money and new parts.

 

Without knowing exactly what they did it is hard to say where the damage may be. Is your car an '07? Did they do anything besides pull the seats out?

The speedo on the '07s is controlled by a little white box on top of the radio - there should be some fuses for it down in the drivers kick.

 

Wait, so you traded your new 07 seats which has memory for used seats off of an 05 that doesn't even have memory? Wow... WHY???

 

The interior that i traded for was done in suede and had glassed door panels for 3 way front stage. i never use memory seats anyway, but we had agreed that the proper way to do it was to switch out the cushion and seatback onto the different frames, and they tried to save the time and just put in the complete non memory drivers side. From what the dealer said, the way he hooked it up (with jumpers to give it power and bypassing the harness) he fed back power into the bcm that shorted it and possibly the ipdm out

 

The stock electrical components are very durable. If the dealership says they are damaged make sure you tell them you want to keep the "damaged" parts. Once the repairs are complete you can then swap out the parts and see if the parts really were damaged. If they weren't return them.

Then again, if hte damage was caused by a shop make sure you ask the shop for their insurance provider information. They can't legally not give you their insurance information. File a claim and let their insurance deal with it.

It would also be beneficial to have the dealership document (photograph) any modifications to the stock electrical systm.

 

Thanks, that was the first thing i did, ask the dealer if he could provide photo-documentation, he said no problem.
As far as the bcm, is there any way that i can test in out of the car cause i am afraid to put it back in? with multimeter or something? The dealer actually told me straight up that he didn't think there would be any real problems with the car and later when he told me the bcm was shorted he sounded surprised

 

no, there is no way you can test it outside of the car - past a visual inspection for any obvious burn spots. I would investigate exactly what was connected where and see if it goes back to the BCM. It's possible the BCM has nothing to do with any of those circuits under the seat.

 

smell it 8-) seriously tough if it stinks like burnt its burnt. i dont see how they could have fried it unless the 2 seats use different motor plugs and they tried splicing connectors wit out disconnecting the battery.. i would look into the NATs system maybe they left the key signal pick up off or sumthing or the keys lost program.. either way all your instruments not working is bad news butch *** job is all i can say sry man gl

 

yes the bcm does have everything to do with the adp system and the power seat system, along with the ipdm/er.

pop the back of the case open on the bcm and the ipdm if they are both bad you can see where it happened most of the time, sometimes though its very small and hard to see follow the solders on the front and back of the bored and look for breaks, thats how i see most bcm's with just slight pops not putting power to where they need to go.

 

i believe that THAT is EXACTLY what happened

As far as the key thing goes, i had though about it but i mean the car was running, so wouldn't it have not started the first time? also i had shut off the the car for a second at a light and restarted to try and see if that would fix anything and it started up

 

Yup, that is what the dealer said, the BCM, and possibly the IPDM. what exactly is the ipdm, anyway? i wasn under the impression that is controlled exterior functions, while the BCM is interior mainly? i am new to the whole nissan thing and used to cars without so many computers and control modules

 

IPDM is basically a centralized placed where they put just about everything. Intergrated Power Distribution Module if i remember correctly. It houses relays fuse etc. Some are solid state relays ac comp relays is 1 exp i kno of that cant b change seperately.

well i have seen cars that had the keys programed for w.e reason drive away and come back on tow trucks and w.e reason the keys were not programed correctly some times the process wasnt ended correctly and allows the car to be started maybe 3 times or so and then it goes into lock mode. but thats prob not the case since u also dont have gagues working.
