2000 Tahoe w/no heat

[JamesForney13]

I have a 2000 Tahoe that had heat in the rear but not in the front. Now I have no heat at all. I heard of something called the re park, does anyone know how to do this or what it is?

Never heard of it. Does coolant get to operating temp? If so i would check into the temp blend motors. They were very common for loosing their position sensor and would not work.

My 02 suburban always blows fire hot in front but no where near as hot in the rear

@8.1HD Yeah the coolant runs around 200° and I replaced the water pump and thermostat last year. I was told it's probably the blending door actuator that is bad.

[8.1HD/ALLISON]

Sounds like temp blend door for sure.

That seems to be what everyone thinks. I'll try that and go from there. Thanks for the help.
