Heating and Ventilation

I am having two issues with my HVAC system, but I don't know if they are related. I am getting bits of thin foam (insulation?) through the dash air vents. With the A/C switched on, there is a water leak onto the passenger side floor. I have checked the drain from the evaporator, which seems clear, but the leak gets worse the longer the A/C is on. When switched off, there is no sign of any water.

The heater in my Boxster isn't getting hot. 

The hvac hasn't worked since I bought the car. Checked fuses and relays, all ok. Replaced control panel as pixels were missing. All buttons work to make functions move on the panel but actual items don't function, except the snowflake dosn't light up. AC compressor dosen't come on. I checked the ac low pressure side and pressure was good. Now the really wierd thing is that a motor under the dash is costantly running when the ignition key is on. I'm baffled.Any ideas? 

The car was put in service (warranty started) Nov. 2015 and I purchased it in May 2016 with 150 miles on it and the A/C needing recharging as I took delivery.  After recharging, the A/C works fine all summer but in 2017 and 2018 when I begin summer use after winter "hibernation" the system needs to be recharged before it will produce any cold air.

While driving my car today I had a red coolant light to the right of the gauge start flashing.  When I checked the gauge it was all the way to the left.  Coolant tank is full.  I read it may be a sensor or an engine compartment cooling fan.  How do I tell which one?  Is either a do it yourself fix?  No Dealer for 180 miles. New Boxster owner sorry.  Thanks in advance.  CJC

I Drive a 2003 Boxster S that has 22,000 miles on it. I have had the car for just over 1 year. Just after I got the car I noticed coolent on the trunk lid just above the Coolent Cap. I replased the cap 7 month ago and now the Coolent on the trunk lid is back. Shuld I try replacing the cap again?

After topping up the coolant level to max. The next day on start up, I have a coolant smell at the rear of the car. I do not see any coolant in the oil or any oil in the coolant. There are no leaks or drips anywhere. I am loosing coolant somehow. After about a 2 hour drive I am loosing about an inch on the min max scale. The car did overheat when I had a thermostat / water pump replacement. The car runs great. Do you have any ideas?Thank you.

With the heat wave we are having, the AC does not seem to be getting as cold as before. I checked the air temp at the center vent and the coldest it would read is 65. With outside temp at 101, should I expect the AC to blow colder?

I hear a noise under my dash coming out of my front AC vents and defroster vent that sound like a plastic fan blade rubbing against another piece of plastic. This noise is only when I am going above 40 MPH. This noise is constant when running 55 on the interstate and is very loud and annoying. Any suggestions on how to fix this problem?David Eilereilerd@verizon.net
