Thank you for using FixYa,com.

I am sorry but fixya has no parts locator service, so we will be unable to help with this.

You got that discription from where or whom?Fuel trim comes in two formsShort Term --- for fuel adjustments on the current start up& driving trip.Long Term---for an avg of the last several times out,& is a factor used to adjust fuel when the engine is cold& first startedAfter the thermostat is open & the temp sensor is satisfied,the computer goes to closed loop & uses the O2 Sensors toadjust fuel (short term)You need the codes produced to diagnose the issueThere could be several things that effect fuel trim.A failing fuel pump,thus low pressure or volumeWorn out O2 SensorsWorn out and damaged exhaust converterAny Vacuum Leaks anywhere on any systemLeaking (vacuum) Intake Manifold or Exhaust Leakseffecting the O2'sCoolant Temp SensorMany more I guessWithout the codes & more discription we can onlysay it has to be checked out & scan tool data looked atA simple loose air filter cover from sloppy work, couldupset things,but would effect both sides of engine,as airin is common to intake,not bank specific

Here is what I show.

undo the trunk release latch to see if trunk stays shut. if it does then check for stuck release button or short to ground on that circuit.

The radiator cooling fan will stay on all the time if there are certain circuit faults in your engine control system. Your computer will do this when certain sensors are not working. I would recommend scanning your onboard computer sytem. The fault codes will probably lead you directly to the cause. The heater/A/C control problem may be related, but then again, it might be a completely seperate failure. Scanning your computer system will help to determine this.Please note that most generic OBD code readers CANNOT perform the functions that you need to do here.
