heater oring and open cheque book

andytlman · Feb 27, 2010

Just started to strip the centre of dash so i can do my heater o'rings this all seems Tobe going well will finish this tomorrow. I have had intermittent open cheque book for the last year usually turn ignition on off sorts but today it stayed on comes on instantly i have full temperature control both sides but no distribution control so whilst in the area i thought the flap for distribution might be jambed removed the servo but found flap functions by hand very easily. Stripped servo no broken teeth. Any idea's on what else it could be?

Could be the potentiometer inside the gearbox that's shot Andy..it gives feedback to the HEVAC for the flap position. There's a post on here from fanatic this week and he has a new one available FOC.
Usual procedure for replacement is to cut the cable to the motor and splice the new one into the old lead using soldered and heat shrunk joints..saves pulling the centre console apart.
PM me your email address and I will send you some info on checking the blend motors.
