Sounds like garage has broken something when working on door. You need someone with Fiat diagnostic equipment. Either a Fiat dealer or specialist.

Ok noted. But self have driven car abt 10 km after door got repaired. Dealer saying its may cost 25000 INR.I am looking to sail my car as early as possible. Maintenance is very expensive and in India local gay not able to understand the electronic /Software issue even dealer does not want tuch electric parts and insists to replace with new one.

It's worth checking the earth cable which is attached to the top of the gearbox

Check the earths as above (the black (-) cable from the battery.. on uk spec cars it goes from a quick release lever clamp on the battery to the Chassis leg then onto the gear box... these are prone to Rot /corrode under the plastic coating and form high resistance to the power flow...

likewise removing the Air filter box from the top of the engine there is a Tiny earth cable picking up (-) for the ECU bolted to the aluminium engine rocker box top cover The alluminium can Gall (corrode) and go white and furry take this bolt off clean the aluminium and the cable ring....
