Toyota Repair Problems? Ask a Mechanic for Answers ASAP
The most common issue is the air conditioning condensation drain hose. You can look at one of two ways down the firewall underneath of the hood towards the Passenger side or the easiest way is to pull the carpeting back on the passenger side floor it is up against the firewall towards the center console area you'll see a rubber hose where it goes out to the firewall. You need to make sure that that hose is clear. Spiders like to build nests in the hose and a clogs it up. If the windshield has been replaced recently it's possible you could have A leak around the windshield. If you still cannot find the drain hose let me know and I'll see if I can locate a picture.
