That is normal. It means it is not stuck.
I don't know if it is or not, why are you asking the internet. Check it yourself.
Sounds like a stuck blend door.
The float is stuck down at the bottom of the tank or you could have a wiring problem.
Hi, It is not the blend door, that is for heat/cold changes. The mode door could be the problem, or stuck defrost door.
You can if you want but its a lot better to replace it so you don't stuck some place.
The switch on the brake pedal may not be working, if you unplug the wiring from it it should shift if this is the problem.
this just happend to me is was low on freon/134a or it could be your blend doors are stuck
Check to see if your thermostat is working or if it's stuck in the radiator hose. This just happened to me. If that doesn't work try changing your fuse.
The air door under the Blazers dash could be stuck, or there could be a vacuum leak on the engine. The door opens and closes from vacuum, directing the air from heat to defrost.
If it's stuck in defrost your battery died and messed up the computer. Disconnect battery for 5 or more min. My 96 cooled and heated ok but was stuck in defrost
It sounds like your vacuum controls are stuck on the defroster I had that happen and I sprayed a lubricant into the vacuum lines and it cleared up
