enen Posted March 24, 2021 Share Posted March 24, 2021 I have a bit of an uncommon 1991 Disco in Canada. Im trying to clarify what the heater controls do. This car doesnt have a/c. Ive read that the 4 vents along the dash(at face/chest level) only blow unheated air I have hot water going to and from the heater core but only luke warm air coming out the foot / windscreen vents Quote Link to comment Share on other sites More sharing options...
Nonimouse Posted March 25, 2021 Share Posted March 25, 2021 The four vents will blow warm air if the far left horizontal control is down - in the up position they blow fresh air. The right hand horizontal control is windscreen (top); foortwell (bottom) and a mix (central) My 200tdi will produce HOT air on speed one after a couple of miles of driving, at around minus 2 external temps. The joy of stripping the dash out completly (a two day job) allows you to flush out the matrix (or fit a bigger one) and replace anything made of rubber, whilst also fitting sound mat Quote Link to comment Share on other sites More sharing options...
