Heater blows only cold
I have a 99 Buick lasabre an the heater
only blows cold air an the temp gauge
stoped working but the car dont over heat
I dont know
You need to replace your thermostat thats why you have no heat because its stuck open so the coolant always circulates and its always cold and your gauge is probably not broken, the engine is always cold so the gauge would just read cold, you also have no heat because coolant doesnt heat up.
