Why does your heater not blow hard on 2004 530i?
why doesnt my heater work on my1985 BMW
What cause the heater to blow out hot air when the automatic control is not working on a 1996 buick rivera supper charge?
under your hood by the fire wall you will see your heater motor and hose coming from your radiator. there is a gate valve on the heater hose, it may have wires to it or a hard wire for sliding. this valve must be open to allow hot water to get to the heater core that is under your dash. if you can locate it, all you have to do is close the gate valve…
air in the cooling system. some are hard to bleed. I've had to jack the car up sometimes to get the radiator fill at the highest level possible. you have to get the air out of the heater core and this problem will be fixed. you might try loosening the uppermost hose at the heater core until coolant comes out. there might be a special proceedure for bleeding this system also.
2000 Cavalier heater blower blows real low even on high speed then it will not blow at all then shut it off for 5 min it will blow for about 10 sec changed relay but did not help?
What would cause the heater to blow cold air the hoses going in and out of the heater core are hot fluid level is okay?
I would suspect the thermostat is stuck in the open position so the water ( and motor ) never reach operating temperature. This is common where hard water ( water with a lot of minerals ) is in people's taps. I would suggest replacing the thermostat and draining out the coolant and replacing it with new antifreeze mixed with distilled water. You could have an inoperative blend air door inside the dash, or the heater…
