My ac/heat control knobs are stuck on my 2005 nissan sentra. How do I fix it?

Check the condition of the heater matrix valve under the dash board. Disconnect any motors or cable connections to it and try operating it by hand. If it is stuck, then replace it.

If not stuck, then check motor operation (if climate control model) or cable routing (if manual only).

2002 Nissan Sentra Defrost stuck. Only hot air comes out.

The blend door in the plenum is not moving. IT could be the control arm or the control or the door or the shaft. You can access it through the glove box.

I have a 2002 Nissan Sentra the thermostat opens, changed water pump. the heater still blows cold air .

you may have a problem with heater box. your air/mix door may have an issue. feel the knobs on the control unit. if the cold/heat know feels kinda funny from the other knobs, then thare is a problem with heater box/cables??

Ac is only blowing to the windsheild and cant figure out why? please help

sounds to me as if one of the doors / air mix door stuck. your model sentra had some issues with that. we were actually removing the dash and complete evaporator box and replacing the air mix door foam that came of and jammed the doors. it also could be that your cable came off that connects from the knob to the evaporator box to switch modes. does the knob on dash turn or is it stuck??when you turn it??let me know.

The selector knob for the heat and air unit in my Sentra ( the one that directs air from the dash to the floor or defrost) turns but it doesnt change the direction of the air flo

This is usually caused by the selector switch being bad on the car. You will need to change the switch for it to work again.

Interior thermostat control is stuck in position that it only blows air in floor, regardless whether its on heat or AC. It will blow hot or cold, just wont allow you to change air flow positions. Also...

check fuses and relays. there is an electric motor that opens and closes a "blend air door' that switches from hot to cold. the other lights may or may not be related. Is is very possible that the plug going into the control unit has a bad connection.

My air conditioning is stuck on the vents in my 2005 Nissan Sentra. I turn the knob and it won't change from defrost. Is there an easy fix or will I have to take it to a repair shop?

well if you don't mind hard work,then you must pull out the panel that holds your knob switches and check that the cable has not pulled out from the knob,clip it back into place and you should be fine,otherwise you should take it to a repair shop,good luck
