Title: automotive ? Post by: HogzgoneWild on December 03, 2009, 01:43:29 pm Ok I thought I might check and see if anyone has had this problem before I pay to have it figured out. I'm pretty sure its electrical somewhere, relay, control swich ect..??? I have a 2001 dodge 1/2 ton, and the heater blows cool. The a/c works fine, but the heater blows cool, it will get warm off and on but goes back cool...anyone had anything similar and can help diagnose the source?

Post by: t.wilbanks on December 03, 2009, 02:04:57 pm my buddy had a 2001 dodge that would blow cold when he stopped, but heated back up when he took off again. i just called him, and he said he had a radiator leak, and just had to add water. May work for you, if its the same problem!
