Hi,

I'm hoping for some quick ideas on what might be wrong :

My daughter is driving our 2000 Dodge Stratus on a long trip from Minnesota
to the east coast. About 2 hours into the trip, she turned on the air
conditioner. It was at first working fine, but then the air flow decreased.
The air is still cold but very little is flowing in, regardless of the fan
level. She says the fan sounds like it's running fine, and the car temp is
right in the middle of the range (so it's not overheating)

I had her do a few experiments :

1)Turn off the air and the fan, leaving the recircluate button off (ie :
allow outside air in)
Slow air flow, air is cold

2)Turn off air, fan, and turn recirculate button on.
No air flow (as expected)

3)With recirculate button on, and air conditioner off, turn of the fan to
the different settings
Slow air flow, air is not cold

4)With recirculate button on, and air conditioner on, turn of the fan to
the different settings
Slow air flow, air is cold.

So it seems that it's somehow related to the venting system, not the air
conditioner or the fan.

The car has about 120000 miles on it and it has been relatively well
maintained.

Any ideas?

Thanks,

Bob P
