Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Car runs hot when ac is off.



when the a/c is on both fans are also on full time.

with that being said, have you checked your coolant level, and re bleed the system? if your low on coolant is went somewhere.......
 
When the car is warmed up to temp there is a bleeder valve on top of the thermostat housing. Crack that open until a steady stream comes out of it.
 


Define hot.

I bet its not even reaching 210º, fans dont even kick on till 212 and 226.

Do you have a scanner that you're reading off or are you thinking that halfway on the temp gauge is too hot.
 


i have been having same issues, but now when i turn on the A/C, the fans dont even kick on. what could this be? Computer going out? Relays look fine, havent taken power and ohm meter to them yet...will do that tonight
 
ok, so a/c on, fans dont spin. the relays for fans (cooling fans, cooling fan 1 and cooling fan 2) are all good, the fuses are all good as well. is there a "drop resistor" on these newer cars like some of the old school ones? or is my computer shot? could be fans...going to check now.
 
so no drop resistor, pulled sensor output off that feeds ECM and fans kick on...wth is the issue? i am starting to hate this car...a decade it has been fine, til now

you pulled the plug in the sensor under the t stat? that would be your engine water temp sensor.
 
that is the hard way to do it, but yet. i pulled it just above on the wire, right in front of the forward set of injectors...same thing, less of a pain to deal with...fans are on. plugged in, fans off. turns out my a/c was so damned low on refer it didnt want to work...at all. now its NICE AND COLD inside and fans work, how they were supposed to.
