Hi all, I have a bit of a problem, lately rats have been getting into the A/C system, it seems they may be getting in via the water drains from the windscreen, behind the front wheels. They are bringing palm nuts into they system and eating the nuts and leaving the husks in the system and since we leave the controls set to recycle most of the time its left on the other side on the flap. So if you change it to fresh it all comes down into the fan and causes a lot of noise. (Not mention the smell) We have taken it to Toyota on several occasions, and they have taken the fan out and cleaned it all out. But at $50 a pop it’s a bit of a waste, so we have done it twice our selves. But we are looking for a solution to stop them getting in. Now I know that the fresh air sucks from below the windscreen but where exactly dose it enter the actual cabin its self ? I am thinking behind the left front wheel. Rats here a big problem to cars around the sugarcane, we were told by Toyota to put moth balls in the engine bay each night, to stop them eating the rubbers, and ****** and leaving their dropping everywhere. It works well, been doing on our cars for about 18 months works well! So, any ideas? Oh, car is an 03 Camry.
