It could be a fault with the air mix door not opening or closing fully.

The engine or cylinders would not cause the problem but yu might have 2 problems instead of one. The heater not working correctly could be due to a clogged heater core or insufficient coolant in system.

The A/C not cold could be due to insufficient freon or a fault in the system.

You should start with the basics and check the above first.
