Ok so after doing some diagnostics with my power probe here is what I found out. The fans come on when the ses light is on. They fans come on when the a/c is on. The high speed function comes on at about 3/4 temp on the gauge which I assume is 235F which is normal. For some reason the low speed function isnt working which is at like 225f I believe. There is no reason the gauge should ever go that high correct? I pulled the coolant fan relay #1 and tried sending power down the lines with no luck, This system is wild. Should I assume its pcm problems at this point?
