Is this the legendary evaporator issue (one mechanic here pronounced it vibrator) am I facing?
When I turn on my AC, there's a loud hissing noise that fades away after a few seconds. This happens every time I start the car with the A/C on.
I had the leakage checked by technicians using gauges and analog meters, but after an hour or two, they concluded that there was no leakage, so it's not an evaporator issue.
What should I do next?
