Hi all. I have been battling a no heat issue for a while now with no luck yet. I have been through the posts on this site and have the LS maintenance manual as well. I recently removed my DCCV and dis assembled it. It all seems to be working correctly. Also, when I unplug it, it should default to the hot condition. That didn't help either. The aux coolant pump is working.
My heater lines going into the cores at the firewall are warm but not too hot to touch as most people say they should be.
I have no fault codes at the control head.
Can anyone tell me how much of a flow is to be expected from the bleed line at idle? After going through the published procedures, I have just a steady dribble and sometimes inconsistent. Is that enough?
I have yet to try a new thermostat but that is next I think. I think the manual says that it should start to open around 190 deg? I pulled mine out and tested it and it seemed to start to open around 180 deg.
Also, when I had the DCCV removed, I blew compressed air through the lines to the heater cores and they seemed not to be blocked.
Any help would be appreciated.
Thanks,
