One of the links that joins the 2 x cold air levers to the vent linkage has been replaced with a bit of bent bar. The link that looks correct is a bent bar with a threaded adjuster in the middle. Does anyone have one of these they don't need?
Also, do you have any of the plastic clips that connect the heater levers to the mechanism levers - round push fit plastic?
Top picture. The link pointing NNW from the right hand mechanism underneath as pictured. Small rod, bent 90 degrees each end with a turnbuckle adjuster in the middle. Have you got any of the clips that fix the heater control arms on the dash to the arms on the control unit as well?
