Appreciate your time to pull together all your previous help into one place.
Thank you.
Thank you.

But then it gets boring in this forum and I might only come back by once a year for the annual BONGfest.

Agreed.
All good things come to those who wait. I'm really impatient which explains a lot.

Any fault obd saying it's a Hall switch, probably a break in the wiring or a connector loose.
That was the two roof faults my car has had.

Yes, but this is a bit tricky! The CTM partially notes down a wrong(!) hall sensor fault, if a timeout occurs. Nonsense, sourced by the microswitches coupling lock.

Yes when i replaced salmon relay the obd readout said there were five faults on hall and microswitches (there were non).
All cleared after i replaced the relays.

Helpful post. For ease of reference maybe it needs to made a sticky / pinned.

Something that never registered or noticed when i opened up relay, was the rectangular object molded on the case paralleling the coil.
Is this a suppression diode or a continuity check resistor?

It's a small resistor with about 80 ohms.

Well a diode would be used to prevent back emf destroying any transistors driving the coil, coil acts bit like ignition coil.
Fairly standard practice with relays on dc circuits.
Resistor might be used to check circuit continuity for monitoring purposes.
Could these resistors break down causing roof to stop.
My roof just stop on relay "failure".
My obd reader said relay failure, it's how i found out to replace the relays.
I tested relays on bench, they worked fine, hardly any resistance on contacts.
But does resistance of coil connections vary from faulty and new.
