As mentioned earlier the car was @ the SC yesterday, but they were unable to locate the problem. The works manager then decided to send a person along with me on a long test drive for which I agreed. I took the mechanic to Thane from Sakinaka for a drive. After we crossed Powai he also realised that the AC was not cooling as required. By the time we reached Thane the AC was set @ 16.5deg and the cabin temperature was 27deg. The mechanic & the worksmanager also agreed that there could be some ice formation inside somewhere due to which the blowers effectiveness gets reduced. As per them there there could be some sensor which is not functioning & they will be taking 2 more days for a detailed check up.
