Make sure heat temp. control pot inline on one of the heater hoses is functioning properly by looking at it while someone inside the car is moving the selector switch slowly from cold to hot several times, you should be able to see or feel the valve moving. if not, check for vacuum at the pot by removing the hose from the pot and holding your finger over the end of it, you should be able to feel the vacuum with your finger. if there is no vacuum check the line for cracks/dryrot, if theres none the switch is prolly bad.if the pot is working make sure coolant level is full, if it is low there wont be sufficient hot water pushing thru the heater core

2000 caddy Seville ...after starting and engine warm turn on the heater and it blows cold air. Fan works / waiting for hot air and then all the sudden it kicks in. Engine at normal temp

Low coolant, if there is an air pocket in the engine it will make it to the heater core. Once there , the air coming out is cold/cool. Once the coolant fills the heater core, it gets hot. If the coolant is fine hot or cold, then have the HVAC system scanned.

What if the heater hose going in is hot and the heater hose coming out is cold.the heater will blow cold air

Possibly the heater core is 90% blocked. open enough to draw hot water in, (hose feels hot) but not enough volume to provide heat from very cold air, 10% hot water gets cold quick, coming from core..
Flush heater core in reverse direction - cold side in hot side out..

Just a theory..

F-250 Heater hot air ouput overwhelms A/C

under the dash is a air control door. It switches the air flow from hot to cold. Sounds like it is stuck part way open. usually those doors are controlled by vacuum motor. The problem could be the dash control or the door. Seldom is it the wiring (vacuum lines) in between.

Check to see that the blend door linkage is hooked up. Doubtful it is heater core, as you had heat to one side and not the other. Check coolant control valve linkage, verify it is moving the coolant valve from off to on when you switch temperature from cold to hot. Verify you have coolant flow to the heater core by feeling the heater hoses where they enter the firewall. If all checks out well, then look at hvac controls individually.

Several possibilities.

1: The heater ductwork inside the car is plugged (usually leaves). You will need to disassemble enough of the ventilation system to clean around the heater core. Some cars you can remove the blower motor and get enough access. Use a short piece of garden hose duct taped to a vacuum cleaner hose to vacuum out as much of the ductwork as you can. If this is the issue check the screens on the air inlets- usually right in front of the windshield, for holes or other problems that would let in debris.

2: Another possibility, the flaps/louvers in the ductwork are not moving. Some have electric motors and the motors or controllers can fail, some have metal rods that move them and the rods can come unhooked.

3: The heater core could be plugged internally. Although a hot supply and a cold return make this unlikely. Remove and clean out, or replace the heater core.
