kasman21 0 Posted November 9, 2007 Hey Guys I have a problem i need to diagnose!! Problem is all im getting is cold air from my heater! I have repalced a clogged Bias valve which i hoped would sort it but didn't. just getting more cold air! I tested the heater matrix wasn't block, water is getting through it and it is not leaking inside the car!! So i presume it isn't the heater matrix or am i wrong?? any ideas would be great as it seems to be hotter outside than inside my rado!! I know similar topics have be ran but cant find anything if the matrix isn't leaking and is passing water! cheers guys Quote Share this post Link to post Share on other sites

colinstubbs 0 Posted November 12, 2007 I'm getting some heat but then it goes. I'm thinking i may have leaves blocking most of air flow through the matrix meaning so that the unblocked bit gets cooled with the extra air passing through it. Does this sound possible/plausible? I do have less air on the hot setting but the matrix would slow it a bit anyhow surely? Quote Share this post Link to post Share on other sites
Jon_vr6 1 Posted November 13, 2007 Are the top and bottom rad hoses hot and the heater matrix pipe aswell when its up to running temp if not you've got a air lock somewhere! Quote Share this post Link to post Share on other sites
