Heater blasts extra hot air when turning steering wheel

Heater working normally until you make a turn. The heat coming from the vent increases and is quite hot. As soon as you straighten the wheels it settles back down. What gives?

    I should add that it doesn't happen all of the time. Maybe 1 out of 15 turns. I can't comment on whether these are helpful suggestions until I get this to a shop to have them check. Thanks for the replies everyone.

Sounds like a problem with the clock spring under the steering wheel if you have steering wheel mounted controls...if not...then there is a wiring iussue with the heater/ac control panel

Check to see if your heater control valve in the engine bay is resting on the inner tie rods. You could be opening the valve and closing it when you turn the wheel and the inner tie rod moves.

How do I confirm a blend door / actuator problem?


blend door concerns heat and cold air ducting flapper. whether electronic or manual truning of a knob there is a movement noise. a motor/s make/s a sound on electronic controlled ones or a turn knob harder at times to turn does this. then feel the changes hot/cold breeze and no breeze etc..on the vent according to what you turn the system on to do. it is best to confirm movement /motion of the internal motor or flapper during night time or early morning in the garage inside the car devoid of noise to hear the motor or flapping movement, must hear some motor effort or feel hand effort if cable to the heater valve is intact/ not snapped to open heater valves on the engine side. then inspect heater cable if heater is not working etc..hope this helps.

I have a 2002 silverado 1500 heater & ac work fine, but hardly any air coming out vents.


Either you have a cabin air filter that is plugged or the AC Evaporator core is plugged.

I have a 2001 monte carlo v6 and it makes a horrible grinding sound when I turn the wheel... and also makes sorta like a loud winding up sound when I crank the engine and when I'm driving. The engine...


Low on power steering fluid, probably a leaking seal or hose, make sure you have enough, it will now proably be foaming because of the air in there. If fluid level is OK, your power steering pump is going out; or both...

Air/heat blower is not working unless it is on high.

Car overheated, had hole in one of the hoses. I repaired hose, replaced antifreeze and now I have no heat and Power steering is hard to turn wheels.


I don't think these two problems are related.
check the coolant level when it cold
bleed the cooling system if need it
check the power steering fluid level and check to see if there is any leak

The fan is on and the heat is turned on just not getting hot


You should check a few things here.

Check the hoses going into the heater core from the back of teh engine (underneath the throttle body).

Check the Thermostat guage and make sure it is not faulty.

Replace the coolant in your car. (undo the plug at the bottom of the radiator and let the fluid drain out) Once drained close the plug and then fill it back up with approved coolant)

Run the car until hot (about 15 mins and then see if there is any hot air coming out)

Bad news will be if your heater core is busted. You shouldn;t wait too long to check this out as a busted heated core (clogged) will eventuallu force the seals open and you will get coolant leaking into your car.

If it is your heater core these are steps i followed to replace mine:

Disconnect the negative battery terminal.

Disconnect the top and bottom hoses from the heater core next to the firewall)

Pull off the steering wheel
Undo the steering wheel bolt.
Undo the 3 screws holding the steering wheel cover in place, unclick them and put to the side.
Undo the centre console
Undo the glove box - you'll need to manipulate the stops on the inside and let it fall to the floor before - undo the two bolts at the bottom.
Remove the Instrument panel, radio, radio frame.
Undo the single screw in the bottom of the casing surrounding the vents control, gently pop out the vent plate.
Undo the 4 screws holding the vents controls in place.
Remove the frames that are holding the vent controls in place (either side of the centre colsoles (or where they were)
Remove the two side vents (push down and pull back).
Remove the two bolts (either side) that are holding the dash up.
Remove the two bolts (bottom left corner, bottom right corner) that are holding the dash up.
Gently pull the dash up and forward to (making sure you don't pull any wires off there guides and place to the side).

Put the dash to the side (resting on the front seat)

The heater core should be sitting in the middle of the dash.

Remove the four bolts (two top, two bottom) and place to the side.

Pull the heater core back and move to the side to clear the holes in the firewall.

Manipulate the heater core to the side and move out through the gap in the dash and the cross bar (it is a tight squeeze but you can get it out)

Installation is the reverse of all the instructions.

when you have finished installing the heater core make sure you bleed the engine with coolant

Top up the radiator - keep the cap off, turn on the engine, turn on the heater on the heater to full, with the engine running keep topping up the radiator as the water runs through the new core...keep doing this until no more water goes through - this last step takes a while so be patient otherwise you will start to drive the car and will have an overheating engine very quickly...
