bigdman Posted January 30, 2006 Report Posted January 30, 2006 in my car when i turn on the heat you can feel heat rising slowly out of the vents but it is not blowing out, this is when the fan is on high. it is the same way when i turn the temp down all the way. i cleaned the intake duct on the outside, and i pulled the whole cover off, i could see the blower fan spinning. but why can't i get any air to come out of these vents?

Supreme Cutlass Posted January 30, 2006 Report Posted January 30, 2006 Blower motor is probably shot Quote
Crazy K Posted January 31, 2006 Report Posted January 31, 2006 a vacuum leak would prevent you from controling or reduce the ability to control the vents. Is that the problem? that the air seems fine coming from defroster and heater vents??? Or Is the return line from the core hot???? Quote
bigdman Posted January 31, 2006 Author Report Posted January 31, 2006 the fan runs fine. i can hear it trying to force air though the vents. the air coming out is hot. very hot.. but there is not alot of airflow. thats the problem. its the same with the defroster and the floor vents. also, if my heater core was plugged would it block air flow on cold to?

Crazy K Posted January 31, 2006 Report Posted January 31, 2006 no it would not, the Heater core is always hot. so when you have the setting to cool air bypasses the heater core. but.... all air passes through the AC condensor, as well as the grill beneath the wipers, where air comes in. Any possibility that you could have a weak fan? Quote
Slade901 Posted January 31, 2006 Report Posted January 31, 2006 What kind of vehicle is this? BTW, I would just like to note when you state that you could hear the blower trying to blow the air. Does the sound of air blowing gradually speeds up if you increase the fan setting speed to high? If it does, check the bottom of the console and see if the air is coming out down there. On my 1990 Oldsmobile Cutlass Supreme 3.1L V6, my vacuum hose to the cruise control was broken and so my controls to the vents was not working as well. I think by default the air vents down at the bottom of the console which is at your feet/floor. Once I fixed the vacuum hose to the cruise control, then the air comes out in any vent position I choose. Quote
bigdman Posted February 1, 2006 Author Report Posted February 1, 2006 found the problem. it was the A/C core, it was plugged up :shock: since the a/c didn't work i just took out the core. i never use the a/c anyway. here is what it looks like. Quote
Crazy K Posted February 1, 2006 Report Posted February 1, 2006 I'm smarter than the average bear. glad you got it figure. work well now? Quote
bigdman Posted February 2, 2006 Author Report Posted February 2, 2006 it works really well. when i turned the heat on for the first time in 8 yrs. dust and lots of air blew out. i was happy, how i have heat. Quote
