no heat!
My 2000 GMC has great AC but this week I attempted to turn the temp up on defrost and it only gets luke warm with the engine at full warm op temp. The heater hoses are both hot! Apparently the hot/cold blend door isn't operating correctly.
Anyone had the same problem and know how to get to that door actuator?

Re: no heat!
Double check your coolant. My stepdad's 04 5.3L had a similar issue and was low on coolant (the hoses were warm also). He had the issue with leaking water pump gaskets.
