Toyota is recalling nearly 900,000 vehicles.
A problem with an air conditioner part could cause airbags to deploy unnecessarily.
Toyota says spider webs are what can actually cause a blockage in a drainage tube from the A/C condenser. That can lead to a short circuit in the airbag system. There could also be a loss of power-steering.
The vehicles involved include model year 2012 and 2013 Camrys, Venzas and Avalons.
