At an educated guess I would blame a blockage in your heater hose to or from the front heater element. first remove both heater hoses that go to the heater element, then attach a garden hose on one end and turn it on, when the water is clear remove the garden hose and put it on the other hose so the water flows in the other direction, when doing this be careful you don't use too much pressure because it is only designed for about 16psi

2001Chevy tohoe Cold air blowing threw back vents but not front vents?


When AC on and cold air from rear but not front is usually a blend door/heater box issue. You may have a non functioning blend door motor that controls hot/cold distribution of airflow

The heat is not getting hot in the front but the back heat blows out hot heat. Whats the possible problem?


If you can get cold air blowing out the front vents, the front heater door is not working properly. If you don't get air blowing out, check the front heater fan and its resistor block.

2001 tahoe front heater not working, rear heater blows warm air


I have the same problem with my 2001 Tahoe. The front blower is working, its blowing strong, but its cold air even with the temp setting as high as it can get. The rear blows hot air. The engine temp guage is at about 210ish which is close to being normal (220). I just replaced the thermostate a few months ago, I don't know if its bad again, or it I deluted the antifreeze too much and it frooze the heater core, or if the heater core just went bad. Any one know what the cause could be?

No air flow to dash vents and feet vents


99% of the time when they do that it is the control head. that is the thing you adjust all your temp settings on. have to purchase from dealer. have last eight digits of vin # when ordering.
