Hi Guys,
Before I get villified, I checked the stickies but the Climate Control sticky isn't coming up.
So, I have a somewhat old and tired 80 VX with Climate Control.
The AC cold side works a charm, as chilly as you like within a few minutes of starting. Auto function works a charm, and vent control is 100%.
However, the heat function isn't so impressive and I suspect it's either the servo output signal from the CC ECU or the servo/actuator motor.
Before I start ripping into her, can anyone tell me where the servo that drives the heater flap cable is located? The heater hose union at the bulkhead is ok, if I disconnect the cable the valve moves freely and send warm water to the heater. It's just not practical hopping out to pop the bonnet and ajust the flapper manually though
Many thanks
