How to fix AC of Mahindra Scorpio
The AC of my Mahindra Scorpio was just repair but again it is not working well. It just goes off and on. When the vehicle shakes sometime the AC comes back.
Is this a good question?

@charlesdee35377 recharge the refrigerant to the proper pressures and see if that keeps your AC working. Check for leaks after the recharge.

As a diyer repairing vehicle ac systems since r12 days, only one vehicle manufacturer I know of uses dye at factory installation of r134a - GM. GM uses yellowish green dye, making it easier for almost anyone willing to buy an inexpensive uv blacklight to illuminate fluorescent dye while looking for leaks. I think this dye is universal for r134a systems but I do not know if its compatible for r1234yf systems. I would not recommend any diyer adding refrigerant, especially cans containing sealer, to find leaks without dye. Sealer simply ruins a system. However, when push comes to shove, refilling with plain r134a with dye may help. However, this can be very messy if any refrigerant with dye is released from poor connections/disconnections.
@notbroken great information. Thanks!
Vehicle ac repairs are not diy (do it yourself) friendly. Refrigeration requires fundamental understanding of sealed systems, operating pressures, controls, using gauges and other equipment to make repairs. Diagnosing and troubleshooting vehicle ac issues can be simple or difficult. Presuming yours uses R134a, a leak may have occurred to a sealed system. Other damage may have occurred from incorrect repairs. You should return to the place that made repairs and ask them why this repair failed

@charlesdee35377 What year and exact model is your Scorpio? What was repaired and what have you already checked?
I agree with my colleague F Dryer. This "It just goes off and on. When the vehicle shakes sometime the AC comes back" sounds like you are not having enough refrigerant. You need to check for leak.
