you cannot fix this issue - such customers are only 5%, the rest 95% who bought -sensor waali gaadi will never spend one rupee on repairing it - everything and every warning lamp would be bypassed with relay and delay timer installation because for them as long as the car moves and has an ac its perfect.
no matter if said car has flower print seat covers and door cards, plastic panels tightened with cut screws and every single wire nitto taped and diesel drenched (which also removes the tape)
Its not just small cars - even owners of larger sedans did that - like toyota crown, cressida, chaser, mazda 929, assorted mercedes benz, the whole horde of BMW E36 that were imported at one time... You name it - I have seen it.
