Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Hear you loud and clear Taffy Evans.... Maybe I am jaded, but I do tend to believe that products these days are produced with a 'designed fail date' to ensure ongoing income for the producer.
Well after spending a week trying to source my own Relay I have come to the conclusion I shall do what everyone else has been doing...
bcw61 do you still have any relays left?
I did mention some thoughts I had about the high failure rate of these in a previous thread,
I may be totally incorrect with this, but, it seems to make sense
"Note2 – below is just a thought I have, not proven.
Looking at the datasheet, it states
“AgSnO2 contact is suitable for the lamp load, inductive load and motor load, while AgNi contact is suitable for resistive load.”
The AgSnO2 contact is identified by the code T.
Based on this, I would have expected the code to be
HFKM 012 SHST, not HFKM 012 SHS
I haven't looked if there is anything special downstream from this relay that would allow the resistive version of the relay, but, it could explain why there are so many issues from this part.
It is possible that Holden have a custom run of these relays that have the lamp contacts, or, there is some other explanation, so, it's not necessary because they used the wrong part."
Picked up my relay today and will attempt the fix tomorrow hopefully.
For those of you that did the soldering yourselves, how did you de-solder the old relay from the PCB? I'm confident with soldering but have never actually de-soldered anything off an PCB before.
Before carrying out repairs on your BCM, ensure that you have an static safe environment (the use of the correct anti static equipment and observance of static precautions would be highly recommended).
Open the BCM and located the relay. To desolder in the absence of a dedicated desoldering station, use some desolder wick or a desoldering tool to remove all the solder from the pins of the relay. Ensure that you carry out the desoldering process as quickly as possible, to prevent damage to the PCB or tracks. If you 'measle' the PCB or the tracks lift off, then you have taken far too long. LOL
After you have correctly removed all the solder from the relay pins, the relay should then be able to be lifted off and removed from the PCB.
If you are still not sure how to go about it, I would strongly recommend that you consult someone who has experience.
