Object above the I\C Pump
My pump went south so I was under there for a sec to see if the connections were all there, they were. But I haven’t had time to see if it the pump or the wiring yet, and its not the fuse already checked that, but while I was under there, briefly, I saw a ceramic resistor just above the i\c pump on the same bracket, what is this???
just read and I know I get this reply "its a ceramic resistor" so let me clarify, what does it do
tks

The IC pump shuts off when the IAC senses the air temp is less than 40 degrees. It's been cool around here, so be sure it's really bad, not just turned off by the computer.
I believe the IAC senses the temp and turns the fan off by using that resistor to reduce the voltage needed to run the pump.

Hum... If my I/C pump ever goes bad/stops pumping? How would one know?

The PCM monitors the I/C pump, so there is a monitored input/output for it. In the event that it fails, it SHOULD set a code, then a light, but we all know how these PCMs have a mind of their own.
As for what turns the pump on and off, Loosebolt is somewhat correct, but not 100%. The IAT doesn't have anything to do with I/C pump control, but the IAT2 does (the one in the manifold). It monitors air temps after the heat exchanger and turns the pump on and off accordingly. We have access to those values in our Autologic software, so I can change the on/off points if someone desired.
