  It has not been REAL HOT since I purchased my '96, but I have had occasion

to run the air conditioner. A couple of questions.



  Last weekend I was running it and it seemed to not be putting out real

cold air.  The ambient air temp was probably around 70 degrees, so it should

not have been to hard for the a/c to blow cold.  I did discover one cause,

when the water started dripping in the passenger footwell.  It was

condensation from the "heater box" due to (I guess) a clogged drain.  I

located the rubber hose and "manipulated" it until I saw water dripping

under the car.  Does anyone have a better way to un-clog this ?  Can you

easily detach it from the heater box so it can be blown out ?  On some cars

I have owned in the past, it was very easy to disconnect the hose at the

box and clean it out. 





  I noticed after a top-down drive the other night that I have another

a/c problem.  I was running the heat (it was around 50 degrees) and when I 

parked the car for the night, I moved the temp control back to "cold" as I

always do.  I left the fan on.  I noticed that the air blowing out of the

vents was NOT even close to outside air temp.  The lever was on "fresh", but

I did try "recirculated" and it did not change.  It appears that the "blend

door" is not opening / closing all the way.  So even with the temp lever in

full cold (a/c off) it was still blowing warmed air through the vents.  It

would seem than this summer this would reduce the effectiveness of the a/c.

I seem to remember reading something on the list or in the archives about

this being a problem ?  Is this common ?  Seems like someone re-adjusted 

theirs to make sure the temp system allowed no warmed air in when the

control was at full cold.  I would assume this would be at the expense of

getting maximum heat out during the colder months.  Around here, this is

the ideal time to test if your system is warming the fresh air.  If so,

I would guess you will be complaining about the a/c this summer.



  TIA,
