Chrysler Repair: water on front passenger carpet: Sebring convert., coolant leak, engine coolant


Question
QUESTION: Roland i have a 2004 sebring limited conv.with 44,000 miles.when using my ac i get an accumulation of water on the carpet of the front passenger side.i live in fla. so i frequently use the ac.yesterday i jacked the vehicle up on the passenger side and used an air compressor to blow out the drain line.there was no obvious blockage.i started the car while still on the jack and ran the ac and had good drainage.after driving the car for a day the leak has returned.do you have any ideas on how to resolve this issue.thank you.

ANSWER: Hi George,
Are you certain that the water on the carpet is not engine coolant rather than condensate from the cooling coils? If you are using antifreeze in the engine coolant, you should smell it on the carpet if it is a coolant leak. If you are using plain water, then you may be mistaking the leak to be a blocked drain rather than a coolant leak in the heater core. The coolant flows through the heater core all the time, even when the ac is in use. The air flow by-passes the heater core under those condtions.
Other than that, there may just be a build-up of crud in the pan that collect the condensate that will need to be removed to keep the drain from clogging up. So check to see if you are getting any drain water where you park the vehicle following use of the ac.

QUESTION: roland could you possibly give me directions on how to remove the above referenced pan, there is no coolant leak.thank you

Answer
Hi George,
I looked at the manual and it gives no specific details. It may in fact be the case that the collection of coolant occurs inside the HVAC distribution housing and that there is a drain tube from that area in the housing under the ac core which goes to the external opening which you have cleared. (The 'pan' was part of the systems of the early 90's which I has assumed was carried forward into the Sebring).  If that is the case you may just have to continue the unblocking procedure. You might try using a flexible wire to probe up the opening as far as you can, and to repeat that process until it gradually clears out. The alternative is probably to remove the entire HVAC distribution housing which is a major job.

PS Another possibility is that the hose that is connected to the bottom of the housing is disconnected so you might try reaching forward underneath at the point where the external outlet for the drain is positioned to feel for that hose and verify it is connected.
