Griff Vent System

[Argent]

Hi All

Anyone know how the 500 Griff, up/down and fresh/recirculate system works (or has a circuit diagram)?

Cheers

Hey bud
I have a 500 owners manual and the bible which doesn’t go into technical detail only general description. Old school would be a servo system but I think it’s ecu controlled and need a better description/circuit diagram and could deal with it

Thanks for getting back.

So what I understand is that the controls on the dash are on a pcb and a ribbon cable takes that back to an ecu which controls the motors in the passenger footwell for up/down and recirc/fresh air.

Is that right? I

I guess first thing is to look at good connections and lack of corrosion

Great response and description of the system.

I don't have the driver's side blower in my 2000 Griff.

I think the first thing is to do is to look at the connections, ribbon cables etc and check good.

I am hoping it's not an ECU issue.

Photos would be good to identify components.

Thanks

I had a pre-cat and seem to remember this:

You have a rotary switch with three on positions to control the fan speed using resistors.

The two horizontal rocker switches control:

1.A servo motor + microswitches to stop travel on an up/down flap in the heater box.

2.A servo motor + microswitches to stop travel on a water flow control valve that controls the flow of hot water through the heater matrix.

Check wiring, servo motors, microswitches & adjustment, if any moving part has seized.
