after driving it for about and hour it will come and work great but l cant let it warm up for a hour.any have any ideas?

Sounds like a bad heater control valve or thermostat or both.

bring it back to the dealership and see wat they can do for u. maybe they can fix it up or somethin like that

if the temp of the engine is ok, l have had problems with the dccv assy on the vehicles, dual coolant control valve, they usually stick, the only way to fix is to replace them, l also have had ign. coils go bad and cause interferance into the wiring system, best way is to scan vehicle and see if any codes and see if the can get mode data 6 inside pcm to see if it detected any engine misses if need more help u can email me..hope that helps

Try the easy way first, flush the radiator and possibly the heater core. You may be lucky and over with slightly clogged heater core. May or may not help but it wont hurt. Good luck
