Heater problem
1992 Pontiac Bonneville 6 cyl Four Wheel Drive 177758 miles
I just put a thermostat in and still no heat. Still blowing out cold air. What do I do next.

Hi there,
With the engine at temp, and the heater on, check the two heater hoses going into the cabin, if no both hot to touch, the heater tap is not on or the core is blocked, try and see if you can flush the core to prove circulation, start here.
