The Left side vent could probably do double duty for the right vent's part of pressure relief.

Already tried blocking the RIGHT vent, externally and internally. It helped some but did not totally alleviate the situation. Obviously, the outer wall still have holes exposed to outside air, hidden in nooks and crevices that's virtually difficult to cover up without detailed information of where they are.

Anyway, the vehicle is 5 years old so I've learned to work around the the rear A/C issues.

Not sure if it's still of anyhelp but there is a body repair manual provided with the service manual for the innova: Toyota Service Information

Doesn't look like there's much holes to plug up apart from the welding seams and the taillight assembly though. The rest of the manual may help with non-powertrain maintenance (since its meant for market with only the 2.7 innova).
