I'm about to lose my mind driving around Sharjah in this heat with a 2016 Patrol that decided last week to start blowing lukewarm air instead of cold. Took it to a random garage near King Faisal Street and they topped up the gas but it lasted maybe three days before going warm again, so I'm guessing there's a leak somewhere or the compressor is acting up. A colleague told me to look for a proper  Sharjah Car AC Cooling Service that actually does leak testing instead of just throwing gas at it, but I don't know which shops in Industrial Area are honest and which ones will try to sell me a whole new system. Has anyone here had a good experience with an AC specialist in Sharjah that actually fixed the root cause on a Nissan or Toyota? I don't mind paying for a proper diagnosis, just don't want to keep coming back every week. Appreciate any recommendations.
