Front/Rear Heater motors not blowing

[busguy]

1995 Bongo. Anyone had both the front and rear heater blowers cease working at the same time, and on all four speeds?
Independently wired the front heater, and that motor is working ok. Fuses look ok and have been swopped around too.
I'm starting to check connections and wiring, but is there anything else that anyone can suggest?
Thanks.

Now found a related earlier post on the subject which hopefully will lead to a solution.
