Engine comes to normal temp, won't blow any warm air. Will try back-flushing cooling system.

S.O.B. The dawg gone heater went out again. I had flushed the system back in April of 2008... four months later, poop went the heat. I don't get it, the A/C works as A/C, The heater works as A/C.... Chevy engineers double jointed or something?

This is the second time that I had to have the coil cleaned. It is cheaper then replacing it. After agreeing to have the coil cleaned for a second time, the mechanic stated that the coil may leak. He also stated that the coolant turns to mush and that it clogs the coil. He said that it is very common in that model. I want to know why the coolant turns to mush.

A/C WORKS GREAT. NO PROBLEM THERE. TEMP CONTROL KNOB NOT WORKING, I GUESS. I TURN THE TEMP CONTROL KNOB ALL THE WAY TO HOT BUT ONLY BLOWS COLD AIR, AS IF THE A/C IS ON. I HAVE THREE YOUNG CHILDREN WHO ARE FREEZING DURING COLD TEMPERATURES. I NEED HEAT. WHAT IS WRONG WITH MY TRUCK? PLEASE HELP.

I have two small kids & I have the heated seats, which I love, but it doesn't help the kids in the back. I have them dressed like Eskimos in the back seat (which inadvertently keeps them from picking at each other, however, it is uncomfortable for them and not as safe.

Well Im up to 118K miles with a truck that the heat went out. My heater core is not leaking.. Coolant level is good. I dont understand it. Where the heck should I start? I take good care of it. The Core is $63 at Auto Zone... but how hard is it to install?
