Rob HB1 90 Report post Posted August 6, 2014 (edited) Have now replaced heater control valve twice and still having issues. First time right side blew cold and now only get heat in windscreen or demist mode. Don,t want to spend some silly amount on a new control valve if something else could be giving trouble Any ideas? P.S had a manual conversion done at Hellbm. Edited August 6, 2014 by Rob HB1 Quote Share this post Link to post Share on other sites

Eagle 1526 Report post Posted August 7, 2014 Probably pay to put 12V across each of the value and see if they are working or not Quote Share this post Link to post Share on other sites
