Cold but warm ES 350
 

Not sure the problem. Es 350 07. Last summer AC started to blow freezing cold on pass side and outside warmth driver side. Took to firestone,told it needed recharging. $325. Passenger got colder drivers got a little cooler .no way near the pass side, tech directed me to Lexus dealer. Oh how expensive. So weather changed. Now get hot again. Took it to a different firestone no money but directed me to dealer. Solar sensor drivers side. No sure.I would at least have some idea from this forum way the problem may be. HELP
