As I continue to move forward, today I was considering the heater fan. I have three to look at, one didn't work at all but two are working.
Here is what happened. there are three wires going into the fan.
1. Black with a blue tracer
2. Green
3. Green with a yellow tracer.
So, I hooked up the battery assuming that the black was the ground wire even though I have never seen a black ground wire with a tracer.
so, black to ground - touched green and it started working
black to ground and green/yellow - nothing.
Now this is bizarre in and of itself as there is continuity when I touch the two green ends and they go to the same junction but only onw connection works.
Then, trying another fan, I accidently touched the green/yellow to the black/blue while touching power to the green and the fan started going much faster.
I am perplexed. Obviously at some level this doesn't matter as I know it works and when I hook it up as per the harness it should be fine but, I sure would love to understand.
I also think see a green 'tube' that I assume is some sort of thermal break?
anyone
thanks again!
