I just talked to a local shop "wala", he said evaporator and circuitry is fine, he will install condenser and will change the already installed compressor [senden] with Denso [Kabli used] and will charge Rs 14,000-/
Upon asking, if the already present condenser be used, he said Senden might put load on the engine and he wont take any responsibility in that case.
Any suggestions are "Warmly Welcome" in this warm season
