jamesmark Posted March 22, 2009 Share Posted March 22, 2009 Air lock, heater matrix (is your footwell wet?), thermostat buggered. Is it actually turned to hot? Quote Link to comment Share on other sites More sharing options...
Blackie Posted March 22, 2009 Author Share Posted March 22, 2009 No water inside the car. It just doesent get hot, It was working fine two hours ago Quote Link to comment Share on other sites More sharing options...
Jamesy W Posted March 22, 2009 Share Posted March 22, 2009 I had this happen about a month ago, one minute it was working fine, then the next blowing cold air. Being a lazy bandit I never bothered looking into it, then last Sunday it just cleared itself after a bit of a spirited drive. Quote Link to comment Share on other sites More sharing options...

stevie_b Posted September 27, 2010 Share Posted September 27, 2010 Air mixer flap linkage may have come unclipped? See this thread, especially post #16 onwards: http://www.mkivsupra.net/vbb/showthread.php?t=49871 Can you hear the mixer flap move when you adjust the temperature dial from cold to hot? Listen carefully for whirring next to the top glove compartment. Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted September 27, 2010 Share Posted September 27, 2010 no i cant hear it , can i get to it if i remove the top box. Quote Link to comment Share on other sites More sharing options...
Stonkin Posted September 27, 2010 Share Posted September 27, 2010 Is the coolant very low? Just a thought, as i stupidly wondered why my van lost heating a while back and the coolant was very very low, topped it up and been fine since Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted September 27, 2010 Share Posted September 27, 2010 no the coolant is fine, i just put fresh coolant in and bled it after i cleand out the matrix Quote Link to comment Share on other sites More sharing options...
stevie_b Posted September 27, 2010 Share Posted September 27, 2010 no i cant hear it , can i get to it if i remove the top box. I can't remember if it's behind the upper or lower glove box (upper maybe), but yes if you remove those you should see the valve being opened/closed by a rod linkage when you adjust the temp control from cold to hot or vice-versa.

Harry Sachs Posted September 27, 2010 Share Posted September 27, 2010 Im pretty sure you can see it from the top glove box Whether or not you can get your gropers in there is a different story. I'm gonna pop out and see anyway. Quote Link to comment Share on other sites More sharing options...

AlexJames Posted September 27, 2010 Share Posted September 27, 2010 This happened to me once, one of the hoses had slipped off of the IACV (cant remember the correct term now), one of the actuators though... The 2nd turbo would never spool up... and oddly, the heater wouldnt get warm either... Quote Link to comment Share on other sites More sharing options...
Ric Posted September 27, 2010 Share Posted September 27, 2010 i had this once, was a faulty control unit, the contacts for the temp control had broken Quote Link to comment Share on other sites More sharing options...

Harry Sachs Posted September 27, 2010 Share Posted September 27, 2010 No idea mate, I've got a gauge panel were mine used to be. I'm pretty sure it's a couple of screws though. Quote Link to comment Share on other sites More sharing options...

stevie_b Posted September 27, 2010 Share Posted September 27, 2010 iv removed all he screws but it wont budge? I'm pretty sure you need to undo the bottom one too: it hides some other screws that are still holding the top one in place. Quote Link to comment Share on other sites More sharing options...
