Doesn't seem to be A/C related. Happens only after it rains. Not coming down the windshield. I was told to clean out the grill area in front of the windshield and beneath the wipers, as it may be full of leaves, pine needles, and other crud that is probably blocking drainage.
I understand that I need to remove the wiper arms to do this?
It's probably the drain for the ac. Do you hear any sloshing when you corner? You can clear it out with soft wire from underneath the car, or pop the drain tube from the bottom of the heater box and clear it from inside the car (passenger side, remember to be quick and cover the hole when you pull the drain how because a gallon or two of water is probably stirring around up there).
Google "camry ac drain" and you'll get all the info you need to find and clear the drain. Cheers, MD
Thanks for the advice.
From what I have read an a/c drain leak (on a 99 Camry) would affect the passenger side, not the driver side.
We haven't noticed any sloshing sounds...
This leak seems directly related to rainfall.
No rain, no leak.
My wife's got an 01. You probably do have to pull the arms to remove the cowl to get directly at the vents. check out this page: http://www.camrystuff.com/manuals/Gen4/Body.pdf and search on "wiper".
But I still think that if the windshield isn't leaking, the only way into the cabin from the front of the car is through the heating/ cooling intake, which goes into a box between the passenger and driver's sides and has a drain on the passenger side. If you take a lot of right turns with the box full of water, the water will slosh out of the foot vent on the driver's side. (In my old Jetta, it would drop the water right on your accelerator foot.)
My 91 Camry started leaking water into the driver side about 10 years ago, and into the passenger side about 3 years ago. The cause looks to me like a design fault. The channel under the wipers drains out a hole in each side (behind the side panels over the front wheels). These drain holes have rubber flaps, presumably to stop dust getting in. What happens is the flaps obstruct the drain holes sufficiently to trap organic material (leaves etc) that has made its way into the channel. After some years the organic material causes the channel to rust through, letting water into the inside of the car. To make matters worse, the water enters directly over some important electrical stuff - junctions, fuses and relays.
I believe, but can't prove, that this is the cause of a frustrating intermittent problem that I have. Although I've done what I can to stop water coming through (various measures that I will not elaborate on unless asked), the car has a fault in the ignition system that sometimes stops the spark from happening. This usually occurs on trying to start the car, but a couple of times it has failed while the engine was running. The failures are unrelated to the weather, and recently have happened when it's been dry for weeks. All electrical tests I've carried out show OK. This has been plaguing me for couple of years. Usually the car restarts within about half an hour, but not always. A mechanic replaced the distributor, but that didn't change anything. The error code is 43, which refers to the starter signal STA, but that doesn't really make sense since the engine cranks and there is always 12 v at the distributor.
There are two big holes (1inch) on the frame underneath, right behind front tires. One oval, and one round on each side. Floor carpet can be seen. If holes are open, look for rubber plugs inside. I found all 4 plugs, Camry 2008 Put the round plug from inside through oval hole, push with finger. And oval plug bottom up.
Normally fenders help, but this car is not from Japan.
