If your air conditioning is erratic.
EXAMPLE: Actual outside temp is 98*F. While AC is ON, my outside temperature reading drops to 38*F and my set temp is 72*F. The blower then propels hot air trying to warm up to set temp.
It is located under the RH Driver Headlamp
I had a difficult time finding any photos of the actual location, so I opted to produce a few of my own.
The harness that the sensor connects to

I have a 1998 GS 300. The temperature reading that registers on my climate control for outside temperature fluctuates alot. It will give me readings starting at -22F (when it's around 70 outside) then start increasing, then starts fluctuating. Any suggestions for a fix?
