Heater Issue

[Bobhon]

Hi all

I'm having some issues with the heater in my recently purchased Tamora. With the hot/cold rotary switch set to max cold then I can turn the blower rotary switch all the way up to max and hear the blower doing its stuff.

If I then move the hot/cold even 1 click towards hot then the blower completely stops and all of blower LED's bar one go out.

Returning the hot/cold back to max cold and waiting a minute sees the blower come back up to max blow without any turning of the switch.

So it looks as if I can't have hot air and a blower at the same time.

Looking through the Graham Varley manual this seems to say that the heater amplifier controller is knackered?? Anyone had and fixed this issue, if so then how please?

The GV manual also says that the LED's go out when you have changed the setting whilst the flaps motor to their newly requested positions. So should I have just waited a couple of minutes and it would have all been alright??

Hoping to take her out tomorrow (please don't let hurricane Bertha blow through the Midlands) so I will give it some more time after asking for hot air and see what happens.

There is a pause when you adjust the heater settings, but it isn't a couple of minutes. Sounds like the heater is fubarred and Paul Smith Electronics is the recognised expert on things TVR and electrical.

Thanks Tony

On the run out today it operated as you said that the fans pause while the hot/cold flap gets to where it needs to be. from max cold to max hot took probably a minute or so. But it got there, the blower came back on and the screen demisted a treat.

As per the GV manual, max cold on the rotary still gave fairly warm air. So I guess that I'll have to adjust the flap setting next time I have an hour with the car.
