I had the same problem with my 98 ranger. the problem is the hot cold air blender door. on my truck the the top of the door where the electric actuater is placed broke and no matter what you selected on the controlls you would get hot air. to verify that it is not the A/C place it in the Max A?C position. this will cut off hot coolant to the heater core and you should after a few minutes get cold air. if that works you can find the actuator locaed behond the glove box door on top of theplastic duct next to the blower motor. the only way to fix the problem would be to replace the unit or do what I did I glued the actuater spindle to the blender door. make sure the actuater is in the same position as the door or it wont work.

Heater doesn't get hot on 96 chevy truck. Blows good, just cold. Replaced thermostat, flushed radiator. Any ideas?


Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

My truck is blowing cold air, on


Heater core would be your best bet, also check to make sure that the door inside the ductwork is actually moving from the cold air side the the hot air side. If you have the manual lever you should be able to feel it moving, if it's vacuum operated you should hear the air flow change as the door is moved.

With AC on cold, Drivers air full hot & passenger side full Cold


that is a good possibilty, but before I pulled the trigger I would try this first. unhook the battery for 5 minutes, rehook it, now turn the key on, wait for 2 minutes, now start the truck and see if the doors now work. sometimes this works, its worth a try.

All i get from my heater is heat i cant turn the ac on, and when i turn off the heater it still blows hot air


Sounds like a stuck heater core valve. Find heater core valve. Under hood, find the two heater core hoses going into firewall. One of the hoses has a valve. Operate temperature control (full heat, then full cold) check that valve changes position. If not either replace valve or control system failure. Also, when temperature control in cold position, one hose should feel hot and the other cold. Temp fix: disable valve to close no heat or on heat.

HOT AIR ALWAYS


this problem is almost always caused by the air temperature control blend door being warped and stuck or by the electric actuator that moves it, the common issue is the blend door actuator. To replace or repair this part requires the removal of the entire dash assembly.

98 chevy cavalier 2.2 L heater problem


hello.....
first in this problem you need to look for cheapest things to do which is start with you thermostat abd make sure its open and close by how much temp inside the eng. then u need to feel the input hose and the output hose which they come from the heater core they should have closely same temp . if there is non of them have any heat thats mean the water pump blower is broke and u have to replace the water pump, if one of the heater core hose hot and the other cold the problem in the heater core , about the A/C light is on the A/C comprasser shoul work with the heat becuase hot air + cold air = dry air which u need for ur front DEF

My air blows hot even tho my climate control is on cold


U have a stuck air temp control blend door, either the actuator motor is defective or the door is warped and has jammed, one thing is that u must remove the dash to rcheck replace these parts.

Heater only blows hot (well, warm) on full speed of fan


Replace the temp control on this car, it should be electrical control not cables.

I can't change the air temp from hot to cold air. Hot only.


the first thing to d is to go under the hood and see if eh cable is stuck if it is not then it has disconnected from its position secondly yu may have a heater control valve which is broken inside which means the water is still flowing nd the heater is on wheher o choose hot ot cold.

the only way t fix the heater control valve is to repace it
