I have a Chevy 2004 Impala. I am facing a weird problem. My heating sometimes work , sometimes does not work. The situation is like , I am going for grocery the car heating is working, when coming back it is not working. If I leave it like that on the next day heating again working. It does not follow any pattern.
Can anyone please help me to sort this problem out?
What fo u mean not working, like the blower motor doesnt come on or does it blow cold air. If it is that ot blows warm air and then it blows no air, it is most likey ur control switch, if it does this again or have you ever tried to turn the switch to low or medium or high when it does this, try that see if it works on tje other settings if it does your switch has a short and will need to be replaced. Let me know more details ill try to help
check your blend door . is the air blowing
Thank You so much for your quick respone jwhalen70 and premier123 . It was in a mode like blowing warm air or no air. Now it is blowing no air at all. Where is that control switch located @ jwhalen70? What is blend door mean @ Premier123? I aprreciate your help in advance. Looking forward to hear from you AA
It is the switch on ur front panel, that has several white dots, that go around in a circle, it also has a picture of a little fan blade on it, the blend door is located in side ur heating systems duct work, this allows u to adjust the coolness to warmth of the air, but if the blower motor works sometimes and not others, it is your turn dial switch has a short and is overheating causing it to malfunction
Actually, I am very familiar of those switch. Sorry I could not catch the name only..I thought you mean something inside the hood ...I tried them in different switch position ...Unfortunately, my blower motor is not working..and it looks like coolant level is also low.....Many many thanks for your reply..I will appreciate if you have anything to add on your suggestion..Have a good one...:)
I would like to update about this issue. The problem was in the blower motor. I replaced it with new one and now its working fine. Thanks AAF
Probably was short motor brushes.
