heat lukewarm and temp low!
so, my heat is now blowing air that is warm but not hot enough to get the cab hot. I also notice that the temp gauge is always rather low, and that the blower itself seems to fluctuate. I'm not about to assume that the blower problem is connected to the other two. I suspect a thermostat, but am not sure if maybe a temp sensor would be responsible. I don't see how a temp. sensor would cause the heat to blow lukewarm, though. this leaves me somewhat stuck. any ideas?
