    I have a squeaking sound that comes from the dash area when the temperature control is in the "blue" region, even when the fan is turned off. Any ideas? It almost sounds like a mouse is in there!

    Also, is it normal that I still get air coming through when the heater is not on? Like it comes through at whatever temperature the setting is on and not just air temperature....

    Lastly, speedimoter doesnt work but we get a reading. Any ideas?

    The spedometer issue...GM has a bulletin out for cluster failure for these trucks. There is a 7yr/70,000 mile (whichever comes first) warranty on them granting replacement. Did you verify a speed reading with a scan tool?
