    i have a question for trouble i am having with my dual climate control heater system, i have a 2003 chev silverado 4x4 with a 5.3. the trouble i am having is that i have all of my heat settings work from fan setting 1 thru 5 but i cannot change my hot to cold setting and it won't shift from the defrost to the vent or floor? this usit also has air conditoning but cannot get to operate cause i cannot control my heat settings. I have replaced the dual climate control cluster and had no success. if anyone has any suggestions please let me know cause i am at a loss. thanks and look forward to hearing some ideas.......
