Bubling Sound At Front Console When Weather Get Warm?

[bugeyes]

When weather getting warmer, I hear bubling sound through my front console, and the heater only put out cool air only unless sets at maximum hot? are they related or how do I fix this? thanks.

Have you checked your coolant level? You could be low on engine coolant, and it's low to the point where it's having a hard time pumping the engine coolant up through the heater core. That would be the first thing I would check. BTW, if you've never checked coolant level before on a vehicle, wait until the engine is stone cold, then open the cap on the radiator... you don't want to get sprayed with hot coolant.

If it's low when you open it (meaning you don't see any down in the radiator, and there is none in your overflow reservoir), then I will fill it
