Floorboards Wet on Passenger Side

Hey guys,

Today I was changing out my floormats on my 2003 Tacoma PreRunner when I noticed some condensation on the underside of my old floormats. A quick examination showed me that there was some dampness on the passenger carpet, particularly on the half closest to the driver-side. It was only slightly damp and feels like water, not antifreeze. I have checked the A/C drain hose and it feels completely clear of any debris. I haven't ran the A/C at all, but do use the defrost from time to time, but not enough to cause and condensation. We did have monsoon type weather earlier this week, but I didn't notice if it was leaking or not at the time. Two weeks ago I vacuumed the truck out and didn't notice any moisture. Any ideas on what this might be? I just got it back from the dealership for some general maintenance and one thing they did was a coolant flushing. Could it be a leak around the windshield/weather sealing? Any ideas would help. I have seen other threads on this type of problem, but mine seems a little bit different. Thanks all!

 

Heater core?

 

There is a tsb on this for 1st gens, the pinch weld under the windshield can develop leaks. Mine happened after warranty and I had to pay about $170 to get it fixed.

 

@OhBrian - I don't suspect the heater core b/c the fluid is clear and not slick, so I think it's just water.
@wtmtntaco - Thanks, I'll probably run it by dealership next week and let em check it out.

 

I also have this problem and cant seem to figure it out after reading the few threads on here on this topic...Ill have to check the windshield thing.

 

Does anyone know exactly which weld it is? Or have access to the TSB?

 

Went to dealership today and they told me that it was actually a bad weatherstrip on the passenger side door that is causing the leak. He said that they typically see leaks at the windshield, but mine already has an aftermarket windshield.

 

Here's the TSB for the cowl weld leak

 

Just discovered wet carpet on my passenger side on my '04 Xtracab. I have the hard plastic weather tech floor mats (so I could never see the carpet was wet) and I noticed a bad wet smell and started investigating. I pulled the carpet up and found two round black seals/plugs that when pulled out, allow you to see the ground underneath the truck. I think those round plugs were not sealed properly and allowed rain water to come through the floorboards. Everything is drying out right now and then I'll put some sealer around the holes and put the plugs back in and see if the carpet gets wet again. Otherwise maybe it's leaking from the pinch weld or the windshield. I'd like to have the issue fixed before it starts ruining things.

I haven't ran the AC in a few months and rarely use the defroster.

 

I was doing a thorough cleaning of my truck after hunting season. Passenger side carpet was WET underneath. Read the forum for clues. My metal 90 degree bend in the condensate line was completely clogged with what looked like a mud wasp nest. Haven't had a problem since.
