Question about 1999 Chevrolet Silverado 1500

HVAC duct doesn't change when control is changed. Heater has hot air, AC has cold air, fan changes speeds when control is changed from low to high, but when control for defrost/panel/floor is changed, nothing happens...Any ideas?

It is in the blend motor under the dash, this is water cycles it between locations. You will have to get it from dealer. It is bolted on under dash on either the passenger side or driver side of center console dealer can tell you exactly where it is. They are not usually that much.

My suzuki alto stantard SZ 5 DOOR 2012 modle heating is now working Please advise


HVAC, the heater is not working?
the resistor only makes fan work , on low speeds.
1: is the fan blowing? heard and felt? on HIGH?
2: is engine coolant at 180F temp, or more holding, IT must, or there will not be heat,.
3: are both fire wall heater core hoses hot, fully? if one is cold the core is blocked. (flush it out)
4: Ok, we have hot water coolant to core (heater core) so is the damper open?, yes, then now you have heat for sure.

if all that is greek , get car serviced.
or buy the FSM book read , HVAC chapter
the factory service manual

2003 Chrysler Sebring, no heat cold air only. Have filled coolant. Hot air will come out with fan turned to high for a minute or two and then it will change to cold only. Any ideas?


sounds like a restriction in the coolant bypass and or heater core. you will want to check if both sides of the heater core hose near the firewall are hot on both sides if so you have an issue with the air ducts but if not then you may have a failing heater control valve or a restriction.

I replaced the top radiator hose, and added coolant it still runs hot and left side air is cold, right side air is hot


Sounds like 2 different issues. Change the thermostat and then check the heater core valve for the left right issue.

My chevy ac blows only on fan speed 5 what could it be


It is a 99% chance you need a new fan speed resistor board.
It is beside the fan motor.... it sits in the heater/AC duct work to use the air flow to cool itself.
It costs about $35 and takes 15 mins to change.
Did you loose one speed then another and now only high works?
That's the usual way they fail.

Heater blowes cold air replaced heater controls and all vales are working the heater core gets hot on both sides so how do i fix this


It seems to me if your heater core is hot, and the fan blows cold air, then your ducting is closed off. Try and see if your duct door is opening up. You say you changed out your controls, but it sounds as though it wasn't your controls that were bad, but what they control is not opening up.
It's all well and good that the heater core is getting hot, but if the fan cannot deliver that hot air passing through it, then walah.
It has to be an air duct obstruction. Either the ducting is collapsed, the duct door is not opening, or you have some obstruction blocking the ducting. My guess, because that is all I can give you without seeing for myself, is that the linkeage or solonoid that opens the duct door is not working. Older cars had a cable, but I believe newer use a solonoid to operate the opening and closing of the door. The door is there so you don't get the heat from the core when you are using AC.
Hope this helps.

AC Cold air but no volumne of air flow


Please check for any blockage and in the ac duct, IF the duct is clean you need to refill the AC gas and get it serviced as the AC thens to weak over the years ........................
