Correct on both counts, your sun sensor is on the dash instead of the hood for some reason, and the in car temp sensor is behind those little grills in the overhead lamp.

The in car temp sensor comes complete with a small fan which blows air from the cabin over the sensor.

Quite often the fan covers the sensor in dust and small debris which makes the sensor less sensitive, so sometimes just cleaning the mess out helps.

It's worth a shot, let me know how you get on.

Is the readings for the temp sensor and outside temperature read in celcius in the climate control system? In doing a reading on the sensors in the car right now and I'm seeing about 30 something but it does not specify if it is celcius or Fahrenheit. This is a US model car btw.

If it does read it in celcius then my sensors aren't faulty. Because translated into Fahrenheit it comes out to the actual temperature outside and inside.

I decided to do a test on my sensor (not a legitimate test) but I took an LED strip that I had planned on putting on this far (not sure where yet) and wired it up to the dome light and put the light next to the sensor. This light generates quite a bit of heat so. I held rest for 5 seconds to reveal the sensor valued and the in car temp sensor actually went up all the way to about 40 degrees. Not sure if it's celcius or Fahrenheit.

For the American model I would expect it to be in F. But it does show the sensor is working, maybe not 100% but working none the less.

Clean the sensor up and see if it becomes more sensitive.

Okay. How exactly do you remove the dome light?
