Checked the Air door behind the glove box today. It does not close with temp wheel in min position. When I press the recirculate button it does not close either. I closed it and put a small block of wood against the frame to hold it. The outside temp is 72. At idle the air temp coming from the center vents is 62. I ran it at 2000 rpm's for 5 minutes and the air temp coming from the vents is 58. It looks as though there are 2 vacuum servos attached to the air door. This car does have a sight glass and at idle there is almost a constant flow of freon. It does have a gap in the flow sometimes. The flow is white looking. I am going to remove the blower on Sat and inspect the evap core. Thanks for all the help.
