Fan not turning on

[mattross]

For what i understand, when the A/C switches on the fan is supposed to come on too. Check out the circuit diagram here, towards the page bottom. Note the 2 speeds and how interconnected everything is to the fan control module. I'd bypass that if your concerned about it

RayRay, what was the fix?
My fans stopped working in our 2.0 cabby.
When I jumped from the fan switch I could only get one speed to work.
Am guessing I have a wiring issue.
Have already replaced; fan switch, fan relay, thermostat.
May also have a blokage in my water galleries but since only one speed kicks in when fan switch is jumped, I'm guessing it's wiring?
Should I have an electric water pump? If so I don't hear it running.

Any help would be appreciated.
Thank you!
