If you remove the n/s parcel shelf,then the philips screw on top of the centre of the dash,this gains you access to the heater control valve,the cable from the cold/hot control sometimes slips through the clip which you will see when you operate the control,had blocked heater rads on these also and also water pump impellers sheared resulting in no heater,would look at the control first
