I have a 2004 Chevy Trailblazer LS, the A/C still works, but when it's on it's leaking. there will be a puddle of water on the passenger side floor. it soaks the carpet....what's causing this and how much to fix it?
Rather than pay the dealer $350+ to fix this, I found the "L" shaped drain hose behind and interior to the front passenger tire (I let the car idle with the AC on and waited for a drip. On my back on groud I reached in and found the drain line and it came off i my hand and about 4 oz of water and some decayed matter floowed out. I reaced back in and found the hole to which the L line was attached. It was a rubber fitting on the end of a metal pipe. The fitting came off easily and then about 8 oz of water flowed out (carpet had been soaked for two days). I reattached the L drain line and noticed that inside the fitting was about 1/4 tsp of "mulch" - decayed leaves, pollen, etc. Reattacted the fitting and water now flows freely out the drain. And yes, its a very high humidity area - Houston, TX. And if you live anywhere near here you know about the intense yearly dispersion of Pine tree pollen. I thisnk that accelerates the blockage. Happen about every 2 years. (Third time for me. First two I let the dealer over charge me for this effort. BE SAFE WORKING UNDER YOUR CAR!
You have a clog drain.
look under need on passenger side and stick a piece of wire or some thing flexible to unclog it.
if this don't solve the problem remove the passenger side kick panel
and find the drain hose than my be loose.
If you live in a high humidity area, this will often happen. There might be a condensation pan under the air unit where it is leaking. It should have a drain line from it to a small hole in the floor to drain the water outside. The line may be plugged up.
