Chris Wilson Posted February 28, 2009 Share Posted February 28, 2009 The wife's old (N reg) Jeep Grand Cherokee 4.0 petrol has lost heater direction functionality. You turn the knob to direct air to say the screen, or the foot wells, or the fascia vents and nothing changes. There's just a trickle of air to the screen even with the fan on full. Not sure if it's electrical or mechanical. Has anyone got access to a factory shop manual? Thanks. Quote Link to comment Share on other sites More sharing options...
