Your t-stat is not opening, unless your temp gauge or temp sensor is faulty... much much more likely that it's the t-stat though. That explains the lack of heat, but you said it is barely blowing any air at all even though you can hear the fan? T-stat wouldn't affect this, so you have two seemingly independent issues here. At least it sounds like both will be relatively easy and cheap to fix. <img src="/forums/images/graemlins/wink.gif" alt="" />
