Power Seat Trouble? Look here for FIX!

OK... I tried this repair and nothing changed. Is there a different relay part number for a 2003 Anniversary edition (1SC)? The circuit board was way different, although the connections seem the same. I guessed at where to heat the solder... but maybe there is another problem.
At this point I am happy to just replace the relay (around $250 assuming it's the same part) but want to be sure I'm ordering the right part. I don't recall seeing a label, tag or part number on the relay.

SCMs are different and what are used with Memory.

Let me try again. DOES YOUR CAR HAVE THE MEMORY OPTION?
If so, you have a completely different module. It is an SCM with a serial bus computer interface. Not, a Relay Module.

Yes. Is that likely the cause for partial/intermittent seat operation and is the part located in the same place? If so, what should I look for to replace it?

SCM is in the same location and a black box like the Relay Module discussed in this Thread. It is what you tried to fix.
The problem might be the SCM or the seat switch. Either can be had as good used from Marc at VetteNuts.com a Forum vendor here.
You could pull the switch and test the contacts with an ohmmeter to see if they are the issue. Normally not all the switch contacts will go bad at once unless these was water on it and the contacts corroded.
If you want to try that I can give you the info to do it.

Seat Module
I think I'll try to solder the connections. I swapped the module from the passenger side and the driver's seat is completely operational. At first I was unable to raise and lower the front of the seat. I took a look at the module and opened it up but it looked ok. Maybe re-soldering will work.

Re-soldering fixed my issue with the rear tilt. I really didn't have to add solder just reflowed the existing especially on the points that were close to an adjacent circuit. I didn't want to flow new solder over to another circuit, it would be such a pain to remove and cleanup.
Thanks for the great how-to.

I just want to say I love you guys.
My seat motor was constantly trying to retract itself in the rear position and would not respond to my inputs. The seat motor burned my thumb upon investigation as it was so hot. I quickly disconnected the switch console and drove it awkwardly home from work and came straight here for research.
I pulled apart my switch console to the seatto find very light corrosion causing a short between three of the circuits on the board. I lightly brushed it off with a tooth brush, 30 second fix. Many thanks and much love for my fellow vette-erans.

Ok guys I am needing some help. I have memory contolled 04 memory seats, I am trying to install them into a nonmemory car. I am wanting the simplest way to make the power seats move. I do not want the memory. I dont plan on reflashing the BCM and putting the door switch in. Is this possible or have I just screwed up buying the wrong replacement seats.

Will this fix any issues with the drivers seat bolster adjustments? The passenger side works but when I move the switch to the drivers, nothing happens. The other adjustment works for both (slide forward, back, recline etc). The bolstering adjustments only work for the passenger seat.

My drivers seat in my 02 Vette won't move forward but moves back and all other directions just fine. I have memory function for the drivers seat, which also doesn't move the seat forward. I took apart the module and looked for cold solder joints but didn't see any. I ordered a new relay and would like someone to please point out which of the two relays is for forward.

If your dr seat is currently unbolted from the floor and your module is out, can you switch the relays and see how it functions? How about a switch with the passenger seat?
My '03 dr seat has power & memory and all functions are normal except that the forward motion is intermittent. It's on the list for a fix after the upcoming Holidays. My problem could be like yours or it could be the seat switch itself.

I ordered a replacement relay from Ebay. Some dude called gaugerepairman has them and they appear to be common components to Corvette electronics. The part is a NEC EP2-3N1S and I already tried DIgikey but they couldn't find anything like this. My plan was to randomly choose one and swap it with the new one and test it. If that doesn't work, process of elimination. De-soldering and removing these relays is difficult, but I've done it. Rather than to have to do it twice, I'd rather just do it once.

Roger that, Dukenukemx. I had my seat professionally altered to go back 1.5" further on the rails and my concern is trapping it in the rearward position and being unable to get to the two rear mounting nuts.
Thanks for the Fleabay reference. I'll watch for other seat components for C5s.
Please keep us posted on your progress.

After such a long time of wanting to fix the issue, I finally got around to swapping the relay and it didn't fix the problem. Tried swapping both with no luck. I took apart the switch and found a lot of corrosion, and with a test of the multimeter one of the traces wasn't working. Little sanding showed that it's disconnected. A little solder and some wire and the trace was fixed. The chair moves forwards just fine now. The new relay is in there, because I'm too lazy to remove it.
This is what happens when you drive a convertible. There's no leak now, but there was plenty in the past.
