Hello Tjack1792, Sorry to hear about this issue you're having. If you would like to private message me your VIN, name, current mileage, I could research to see if there are any recalls or special coverages related to the issue you're experiencing. My email address is socialmedia@gm.com/ Subj: line: Attn: Vanessa. Also, I would suggest having your GM dealership do a diagnosis on your vehicle as they would be the best resource of determining what's wrong. Vanessa GM Customer Service

First thing you should do is check your coolant levels and top it off because if you have air in your cooling system, the engine can't pump hot coolant through the heater core properly.

Also to go along with Dorian check the temp of the lines going to the heater core with your hand. They should both be near engine temp. If they are both cold then something is preventing flow and if one is hot and the other is cold then there is a huge air pocket in the heater core. If they are both engine or near engine temp then its something in the car under the dash. Like a door not moving. If its stuck on AC then it will blow normal temp air since the compressor isn't running
