I have quad 4 2.3L 95 pontiac grand am that I just bought a couple of weeks ago. It has 103,000plus,,I am not getting any heat,, I am getting cold air. Its not leaking coolant in my car. I was told that the heater core was bypassed. So could it be the heater core or the thermastat that is causing me not to get heat

If the heater core was by passed that is likely the reason. The heater core was prbably plugged or leaking and the reason it was bypassed.

The heater core is like a little radiator the the blower sends air across and provides heat.

Suggested Repair

Replace the bypassed heater core and restore the heater hoses so coolant can flow through it and provide cabin heat.

Conversation Summary

A 1995 Pontiac Grand Am with a 2.3L Quad 4 produced only cold air and was not leaking coolant. The owner had been told the heater core was bypassed. The expert explained that a bypassed heater core, often due to plugging or leaking, would prevent heat because cabin air is warmed as it passes over the core. After the heater core was replaced, heat was restored.
