Question about 2004 Pontiac Montana
My 2004 Pontiac Montana blows cold air through the defrost and hot air to the floor vents. I installed a 205 thermostat. Engine temperature is good. I removed the windshield and upper dashboard to check the flaps. They seem to be working properly. Is there any way that cold air could bypass the heater core to the defrost system? We could not see any way that is possible. Thank you
There is a mix damper inside your duct that controls the heat over heater core and ac evaporator that to your floor and one to your defrost. it is probable an electric actuator, that is not functioning properly. If yu can locate it and manually move it, you might have to remove the actuator motor first, you should be able to figure out your problem, I hope this helps! merry Christmas!
