i recently had my a/c unit charged and noticed that it doesn't drain underneath the car. it seems the condensation is now coming in the passenger side foot well from an insulated line. what's the best way to clear a blockage in the compressor?
thanks...

First choice is to get under the car and clear the drain hose that is in the tranny hump near the center console of the car.

To prevent condensation draining to the interior floor pans, two conditions must be met:

1. the rubber evaporator drain line that goes from the evaporator housing through the transmission hump and out to the undercarriage, must be clear of debris

2. the various metallic hoses going to and from the evaporator must be insulated from exposure to ambient air (which contains moisture, which will then condense on the hoses and then fall to the floor/carpet/floorpan). In most bricks these hoses are covered with a putty or a black butyl substance. Volvo's AC retrofit kits come with rolls of butyl for this purpose. See this illustration:

Note that the expansion valve is NOT covered with butyl--do not insulate the expansion valve.
