Finally got the fault codes to display on the car, the codes are 48,52,54,56 then just repeats them. Ive checked the blend door spindle and its connected and doesnt appear to be broken, you can feel the thing turn when operating it by hand, ive checked the motor which again seems fine it turns both ways with 12v applied. Im suspecting the control unit as im guessing its not sending the signal to the motor to move hence the temperature is constant.
Any thoughts? im hoping the fault can be suggested before i start throwing money at it again (its cost me over 1200 quid in 6 months so far!!) but the thing is actually running perfectly at the moment so im hoping to keep it for a while! You can hear something moving when adjusting the temperature knobs but there doesnt feel to be any difference in the temp of the air coming out of the vents. All the directional vents appear to be working too. Would appreciate any ideas/thoughts
Thanks!
