Fresh/recirculating air flap.
Discussion
I'm new to the Griff world, having recently changed from a V8S. There are several things which need attention, some of which I'll tackle myself.
The first thing I want to fix is the fresh/recirculating air flap which does not work. When the switch is turned the flap motor does nothing. I'm assuming that the motor has seized or gone open circuit, though I haven't checked the voltage at the terminals yet. If my assumption is right and the motor is duff where might I buy a new one?
As it's also the custom on PH for new members to post pictures of their cars, here's my '96 Griff 500...

Nice car,lovely colour
.
If you don't find a voltage at the motor,then you might want to play around with the contacts at the heater 'ecu'(check the output voltage there first also).The pins in the white nylon connectors on the ecu can make very poor contact i've found,and even when they visually look good,can still be poor.

Similar problem just occurred with my screen/feet motor control. Other two motors whirr away fine, but this one has gone dead. Maybe a coincidence, but I had just disconnected battery to reset immobiliser. Do these motors have separate fuses, or is it 'one for all' for the heater controls?
I've made some progress...
Disconnected the battery and moved it away from the flap motor.
Undid two cross headed screws/nuts which hold the flap motor plate to the brackets on the inner wing.
Unclipped the flap actuating rod from the motor.
The above enabled me to turn the motor plate in order to see the travel limiting micro-switches.
Lo and behold, I found that a spade terminal had dropped off the upper micro-switch. I replaced the spade terminal and the motor now works again.
All I need to do now is re-fit it. I'll try and take some pictures to post here in case it helps anyone else.

Please do, i didn't knew there was such a flappy thing in mine.

Yep really basic thing. Basically a Plastic box with a few hoses into/out of it. With a big foam covered piece of Square flat plastic attached to a hinge and the motor. That moves the air coming in to the up vents or down vents. Voila
Situated as yu look into the footwell to the top right above the battery tucked right up. Nice and easy to get too

All sorted now. Flap control motor now back in place and working.
The first picture below shows the motor in position. The flap is on the left, covered in foam. When in the position shown the flap is set to re-circulation mode.
Note the small black disk, with three wires attached, hanging by the motor - this is a potentiometer and by turning it you can adjust the amount by which the flap opens and closes. It should be attached to the motor where it engages with a small flat ended spindle.
What can't be seen is the lever on the motor spindle which connects to the flap actuating rod.
The second picture shows the other side of the motor which you can only see when you have unscrewed the motor mounting plate. The two micro switches cut power to the motor when the flap is fully opened or closed. In my case a wire had dropped off of the blue microswitch causing the motor not to work at all. The leaver on the motor spindle connects to the flap actuating rod.

btw - I forgot to point out that in the first picture the black cable disappearing into the flap goes from the battery to an Accumate charger, obviously the numptie who fitted it hadn't figured out the the flap was supposed to close. Maybe that person also knocked the connector off of the microswitch.
Holy Thread Resurrection Batman !!!!
Not really, I contacted Andrew via PM and he very kindly refreshed the photos for me.
Hi Andrew,
Can you help me with the orientation of these pictures
Is this one looking behind the battery box from the left looking towards the tunnel? (I'm impressed you got this picture if it is!)
And is this one looking over the top of the battery box down towards the floor?
Thanks

Ian,
I think that you're just about right with your interpretation of the pictures.
In the first one my camera was pointing more or less horizontally into the gap between the battery box and the bottom of the 'A' pillar. The second picture was taken with the camera pointing slightly downwards over the top of the battery box.
The flap and motor sits bout level with and forward of the lower door hinge. The flap is basically a hole cut in the fibreglass box section at the bottom of the 'A' pillar, presumably there is an opening somewhere forward of the front wheel arch into which 'fresh' air can flow.
I hope that helps.
