Everymorning , both my TLP 02 fans start to run as soon as I turn the key to start position even if the ouside temp is cooler then the climate Control set temp .
I think that indicates the A/C kick in and turn both fans ON .But it's normal that A/C will start early in morning and outside temp is cooler then climate control set temp ???
What sensor will start the A/C ?

Any thoughs , guys ?
Thanks
