Heater
The heater on a TR6 is fairly standard. Hot water from the engine circulates through a core, and a fan blows cool air over the hot core and into the car.
Flushed out the core, painted the housing and sealed it with foam.
Took the motor apart and cleaned the commutator. The brushes looked ok so I didn’t replace them. I hooked it up to a battery and it seemed to work fine. I’m fairly sure it will be pretty useless at demisting, but I doubt it was much cop when new.
all done and back on the shelf
