The temperature blend door on the driver's side might be broken or stuck. Also, if this vehicle does not have the correct amount of refrigerant, it will do what you are describing.

The lines should be differant sizes.. Did you check it? Ther should be a diagram on the cover over your radiator showing you the set up.. Hope this helps..

I have a 1999 Cadillic Deville. The low Frefrigerant indicater come on after about 15 minutes of disconnecting the battery power. Each Time I reset the power the air conditioner comes back on for a while then goes out. I have taken it into the local auto repair place and they find no problem with the unit.
Could this be a intermittent connection to the computer. They have replaced both sencors and the problem persists. Where is the computer located on the car that handles this AC sensor message?
