I am wanting to purchase an SSR RDM module that has the electrical connections with understanding the electronics are totally shot and of minimal to no value. I have checked the web but have not found any failed units posted.

I recently retired as a Process Control Engineer and am thinking of taking up challenge of trying to get a working solution to the many roofs, windows and AC units stuck in their present condition. I have some ideas on implementation but they are strictly vapor-ware at present and admittedly could die on the vine if determined to not be worth the effort.

I would also ask if anyone knows of another device that may have the same electrical connector type that could serve as a donor electrical interface housing should a totally defunct RDM be impossible to acquire?



Thanks,

We certainly NEED someone to be successful in this endeavor. I am sure that there will be a bad RDM's available as soon as they notice this post. We all wish you the best of luck as you tackle this monster! 馃檹
@Autoprof Do you have one?

NO, Sorry I do not have one. All The members I have helped have their bad ones

I think the problem is most people are hoping someone will come up with a fix, then they can get theirs repaired and have a spare or possible sell it and recoup some of the cost they paid for theirs. Just what I have gotten from people when I talked to them about their bad RDM

I have talked to one person that has a bad RDM and they are also looking at that same idea Bruce ... However, if no one has an RDM to experiment with we will NEVER find a fix...
They will discuss it and make a decision.

I understand the problem and was relaying what I have run into when I have sold an RDM. I have had a couple over the years and tried to get the old ones back. One wanted half of what he paid for the replacement for his bad one. Others gave me the excuse they are waiting for someone to figure out a repair so they can get theirs repaired then. In this case don't shoot the messenger. I have tried to get a bad one and had no luck.

Another thing that will be needed for someone to set into try to work on one, will probably need the 4 plugs that plug into the module. Those along with a nice section of wire off them. As close as the pins are you would not want to be trying to test pins on the module and possibly shorting out another pin while just trying to test input or output.

And to do a complete test board you would probably almost need the entire wiring harness out of a truck. The RDM goes back to the roof, doors, bed cover, and the AC system. Plus, is it known where the power input signals all come in from?

There is going to be more involved then just having a bad RDM to look at. I am not trying to be negative here, just trying to put some other things out there to be considered.

Grand Valley Auto Parts had an RDM for sale this morning for $2600.

@BassClef3, I / we, appreciate your effort. Not intending to put additional work on you, but have you thought of contacting salvage companies like above, or, Cleveland Power and Performance, J&J, and I forget the other SSR specialist. Someone might offer more names and contact info. You could also ask them about the Electrical connectors / harness you will need. I'm sure they wouldn't post them online but a phone call might turn up something. ! ? Good luck .

I may have an RDM to donate next week. PM me to discuss.

To help me better understand the challenges of repairing or creating a new RDM, is it the electronic schematic for RDM that is needed, or the software code and signals the RDM sends out?

Both there is no schematic for the RDM. We do know it is a multi layered board but what signals it sends to where and when is the unknown. Even who actually built them is still a mystery.

And another plug in harness piece I would try to get would be the one that plugs into the switch plate on the shifter bezel. Because that is where the signal starts with top down command. We also know there needs to be a signal from the brake pedal but that could easily by passed once the wiring was figured out for the input of the brake pedal being applied.

If you just start thinking of all the input information that it has to register as either closed switches to allow the roof to work.
Speed sensor
brake pedal depressed
bed cover closed
then you get into all the top switches and the sequence they have to go through. Electrical signals to open the latches in the header, signal to the pump, TFal switches.
Plus how much of this is ran through relays or redundant switches?

I suppose this is pretty naive, but has anyone ever tried to contact GM and tried to find out who manufactured the original module? Pretty sure it would have been an outsourced item with a third party manufacturer. GM just might have the technical specs stored away somewhere in their voluminous archives or the OEM manufacturer could possibly be in a position to make a short run of the product from the original specs. I realize this is perhaps pretty far fetched but has anyone ever asked or tried? Just asking!

Yes, many times. American Sunroof Corporate built it but the owner died and the company closed. Mike Moro probably knows more of the story than anyone. Look up a post RDM - Roof Door Module REACHING OUT TO GM FOR HELP?

Yes Sir, several have contacted GM with no assistance for numerous reason... I know it's seems ridiculous that a multi billion dollar company has no help for us. Yet, it seems to be true...馃が

As others have said, to answer your question, yes, many times. There are folks here like Marc (@Marc NY) that worked for GM and still have direct contacts, past and present - several that designed and built SSRs - but they've had no luck.

SSR RDMs have been dissected numerous times by numerous smart and able folks. IIRC there is at least one if not two that currently have RDMs and were/are working on figuring things out by using some of their European auto engineering contacts but no one to date has identified the details much less how to fix them.

It's has been a deep, deep rabbit hole for a number of folks here, some with decades of electronic/engineering experience. I try to keep up on the topic and AFAIK no one has been able to solve this mystery.

I know that we're all saying our prayers and sending good will to anyone that's trying to get this particular part sorted out. It's the SSRs only true Achilles heel.

Using the "Search Community" box at the top of every page will reveal dozens and dozens of threads on the subject. Happy reading! :cautious:
