The first thing to check is your coolant level. If it is low then it will cause this problem. Check it and let me know.

I have checked the coolant level and it is fine. The hoses also get hot, but the heater blows cold within 2 - 3 minutes after you turn on the blower. If you turn the blower off for a couple of minutes it will be warm air again for just 2 - 3 mins.

Did you check the coolant level in the radiator and the reservoir? I would check both and add some if it will take any.
If it is good then you are looking at possibly a restriction in the coolant hoses or heater core.
It could also be a problem with the blend doors or actuators.

Seems the blend air doors are not operating correctly and a scan tool is required to check for trouble codes.

I do not have a check engine light, but I do have a scan tool.

The scan tool must be able to retrive B and U codes. It would not trigger the MIL as this is a separate system.
