Question about Cars & Trucks
If you are getting hot water/coolant to the heater core and still no hot air coming out the vents, then it's a issue with the climate control or blend door. After running your engine and it reaching normal operating temp, locate your heater hoses that goes to the heater core. Carefully touch them to make sure both hoses are hot to the touch, if they are, you are getting hot water/coolant to and from the heater core. So, then it will have to be a issue with the climate control in the dash or either the blend door in the air box. It's a common problem for the climate control to go out on these models, hope this helps.

You have an air pocket in the cooling system. To bled it out you will have to park vehicle on an incline or jack up the front end untill the radiator cap is higher than the heater core. The remove radiator cap and run engine until warm then hold rpm to about 1200 rpm's and top off coolant level until you have no more bubbles.

Has the car been changed coolant since it was bought? If it is time to change, let do a flush through a heater core. There are 2 coolant hoses going thru a fire wall. One for coolant in and one for coolant out. Heater only works if coolant is flowing through the heater core. Therefore, there are one or both following cases contributes to the problem: 1-If the valve control coolant flow gets stuck, then it always closes so there is no heat. 2-If the valve is working, but the heater core gets clogged up, then there is no heat.
