Hello. Welcome to Just Answer. Please allow me to assist you. Before we begin, was the AC being used prior to seeing the leak, or, was the vehicle in a large rainstorm? thanks

No. We just had a 10" snow fall. I have had this leak for about 3 months and have cleaned out the AC drain. Any suggestions?
Toyota Mechanic: Toyota Service, Toyota Expert replied 2 years ago

Thanks for the reply. What you probably have going on here is a blockage in the cowl drains. On either side of the cowl panel (which is open to allow fresh air to enter the heater box), there are drains that allow any water that enters into the cowl area to drain out. If these drain passages get plugged up with dirt, debris or other substances, the cowl panel will fill with water. This water can seep thru body seams and can also, if the water gets high enough, enter into the fresh air intake on the passenger side of the cowl.

The thing to do here is get a bucket of water and pour it into the cowl opening. Water should pour out from under the vehicle, from the bottom of the cab, behind the front wheels. Water should pour out at a rapid pace. If it dribbles, a strong wire (a coat-hanger works great) can be used to poke thru the hole and loosen any blockage found.

I have had the mechanic run water over the air intake screen located in front glass for an hour but found no leaks. I have also had the AC drain cleaned out by blowing air and a rod to pull trash out it appears to be clear.
Toyota Mechanic: Toyota Service, Toyota Expert replied 2 years ago

This issue here is not running water, it is water retention. Assuming the cowl drains are clear, and the cowl seams are good and tight, the front body seams on the firewall) have been known to leak, and, I just resealed the body seams on the back of the cab on a similar truck. Water was coming in from the rear cab panel and getting onto the front floor. Removal of the pickup bed was necessary to complete the resealing of the leaking rear body seam. You might want to water test the back of the cab. And the sunroof drains if this vehicle has a sunroof.

Additionally, if your vehicle has a sliding rear window, these too are known to allow water to get onto the floor, travelling under the carpet.

The front passenger water leak was found dripping from the fan housing. It has nothing to do with the rear of the truck. I have check the AC drains and had them cleaned. I have a wire screen over the front intake vent to the fan housing that came on the truck when I purchased it. any more thoughts?
Toyota Mechanic: Toyota Service, Toyota Expert replied 2 years ago

If you have water dripping onto the fan housing, your intake snorkel is leaking where it attaches to the cowl. This takes us back to clogged cowl drains on the passenger side. That, or the base of the windshield is leaking.

How do you get to this clogged drain?
Toyota Mechanic: Toyota Service, Toyota Expert replied 2 years ago

You remove the cowl panel and use a pressure washer to blow the debris out.
