The center console fridge/freezer will not turn on when cool or ice mode button is pushed. Both buttons will light up in the pressed position but will not stay lit up once button is released. Fridge blower not running too. Had issue once before, fixed A/C leak and fridge started working. Had shop top off A/C sytem and fix small leak at low side valve (A/C was still running cold before topping off). Due to work schedule haven't started further diag. I suspect one of the following: Switch, Thermistor, or Expansion Valve. Thoughts or experience with this issue? Thank you
