Hi all I was woondering if I could get somefeed back from you guys pretaining to my heater. Well the heater does not blow hot, I checked the heater core hoses and when up to temp I notice they are both very hot, do I am assuming the heater core is not blocked, While checking this I noticed my AC compressor clutch was engaged, so I went into the cabin and the climate controll dial that goes from blue for cold to red for hot, does not seem to be changing, There is no resistance and I do not notice any change from blue to red. Any ideas on what this could be would be greatly appreciated. Thanks again, John
More than likely it's just a cracked temp knob. I just went through this on mine. A little glue and a vice to clamp it back together and all is back to normal. Just grab the knob and pull straight out.
If both hoses are hot then its not the core. +1 on the a/c compressor kicking in when on defrost. That is what removes the moisture from the air. If the knob doesn't have any resistance, which there won't be much anyways, then it could possibly be the knob is cracked like said, and like said just pull straight out on it and it will come off. The blend door is inside the airbox. It opens and closes when you adjust the temp. Is that the only thing that doesn't work? Can you change from vent to defrost and floor?
How long does it take for the return hose coming from the heater core to heat up? Mine took a good while to heat up and would sporadically blow warm air. I flushed the heater core by running water from a garden hose through the return line which came through the input and into a bucket. I then flushed it the other way and did this back and forth a few times. Now I get pretty good heat and it blows hot air constantly
Hi all thanks for the help, The air ducts shift fine between defrost, floor, Just cool air not hot, The heater core hoses are heating up together they reach around 180 on my temp gun so I am happy knowing it is not them, I will try the knob
Also, mine was swapped from 4 cyl to 6 cyl, the check engine airbag and some other lights are always on…. that's not as big of an issue for me, but would be nice to get that all worked out as well… any ideas??
