Hi,

My Bonneville SSEI is blowing cold air after the heat has been on for 15 to 20 minutes.

With a warm engine running and the heater turned on, can you feel of the heater hoses, see if they are hot?

A dirty or wet cabin air filter might cause reduced performance?

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
