91 FJ80 3FE
Now that the days of cold are coming up, I'm finding I do not have adequate heat coming through my dash vents. I've had this thing for about a year now and haven't had heat since taking ownership
I've read trough countless topics/post and followed most of the suggestions. For the most part, they all echo each other - Bad heater control valve, T-stat stuck open, flush heater core etc. I've tested the new T-stat for functionality and it works properly.
This was completed about 3 weeks ago:
- The heat coming through the floor vents is hot and can warm the cabin somewhat, however, this isn't going to help when I need defrost. The heat is consistent and never fades.
I don't know that there is air in the system. I spent time with a funnel while it was running to burp it. Plus, the fact that there's pretty good heat in the rear floors, has me scratching my head.
I'm just spitballing here... Is there a blend door or actuator that could be faulty? I'm guessing most of that system is mechanical anyway? Sounds like its operating properly.
Usually I can figure these things out but this one has me stumped. I'm pretty jealous on posts in other places saying the heat others have nearly sweats them out of the cabin. I want that... or something close enough to it.
