There was a question above by LALFAN about Dodge Stratus cooling fan that was not clearly answered for my application. I have the same question so I will word it differently.
Schematic is unclear because I do not know what happens in the PCM.
When the low speed fan runs, there is power supplied by the green wire to fans. When high speed runs, is there power to fans by only the yellow wire, or does high speed occur when power is supplied to both green and yellow at same time?
It seems upon testing that there may be three speeds. Low (green), medium (yellow) and high (green and yellow). Are these fans mean to run only low (green hot) and high (yellow hot) separately or is there an occasion when both green and yellow are powered?
