Water sloshing inside interior A/C and heater unit
Water appears to be sloshing inside vehicle A/C and heater unit forward of front passenger seat. It appears to be worse after vehicle has been sitting a few hours or overnight and goes away after vehicle is driven for a short while. I have checked the outside drain in firewall, which I have installed a 90 degree elbow (exit down of course), and condensate is dripping out. There is no leak inside the cab and carpet is dry. A/C and heater operate normally. Would it appear that this is normal? A/C often 'hisses' after vehicle is shut off as if pressure was equalizing inside unit. you thoughts or experience would be appreciated. Thanks, Jim

sounds like you have air in one of the lines, go get the fluid changed at the dealership

Thank you,
I wasn't sure if you were pulling my leg so I looked it up...thanks for the tip, I now know what the problem is and how to fix it. I really appreciate your reply. Jim

Thanks to first responder...
I don't know why that wasn't obvious to seemed so simple after I read your answer that I thought I should not have even presented the question.
Thanks for your response...I think I will try to get the air out myself by the second responders' solution and if that doesn't work I will take it to the Dealer as you suggested. Thanks, Jim

Now I have a new problem...
When I started the process of getting the air out of the system tonight I could see that the water level in the radiator was low. That alone may be the reason for the air in the system. Tomorrow I plan to fill the radiator back up with anti-freeze and see what happens. If the sloshing is gone I'm all set...if not I will try the 'burp' procedure both responders in effect suggested. jOf course all of this brings to mind the reason for the low water level in the first place... BTY temp guage indicates normal range. Thanks. Jim
