Need any help available. Here's what I know so far.
1. Heat blows cold
2. Blend door and the electric box that changes blend door is working. (More info below)
3. I removed heater hoses up near water pump and flushed in both directions with good flow.
4. I removed only the exit hose from core and cranked engine for a moment and had good HOT water flow coming out of core.
5. At one point, after flushing, I started to get heat but it only lasted for a day or two.
6. While I had heat, I removed the blend door controller and verified it works and when I manually turned the blend handle the door changed the air coming out of the vent from cold to hot.
7. While I had heat, I verified the cold/hot dash switch & the blend door were working. Air coming out of vent changed from cold to hot.
8. When I have the heater on, it sounds like my A/C compressor engages from time to time. It's identical to the way the compressor kicks in when the A/C is on. The engine idle changes and I swear it's the same. (For some reason I haven't checked under the hood for this yet, but will today)
9. Im hearing a sound in my upper dash that resembles a ticking clock. It somewhat sounds like a plastic gear that's slipping or teeth broken as it turns but....is there anything like that for the heater in that area? I guess it could be an unrelated engine tick that I've never noticed but sound like in upper dash near middle
Please tell me someone has an idea? Thanks in advance for any info or suggestions.
