[Healeys] Heaters

[Rich C]

Robert,

As a new owner you shoud have checked out the blower before the day you were 
going to need it.
 No, in the case of a Hundred, the blower oerating or not would likely have 
no bearing on your safety check. The blower simply recirculates inside air 
through the core fins and back out again, having almost zero defrosting 
effect, especially with no top up.

Two black wires with male bullet ends come out of the blower case from the 
rotary switch at the face of the heater and go toward the firewall. One of 
these will fasten to a spare green wire and the other to a black ground 
wire. When you turn the switch on clockwise, it will be full on and reduce 
speed the further clockwise you turn it.

I recommend that unless you have further problems like the fan blades 
hitting the casing, that you leave the heater mounted where it is, but the 
clips can be unsnapped to allow a bit of access to the switch wires.
