Got a '01 Deville DTS. Turned the A/C on for the first time and put both the passenger and driver temps as low as possible and only the passenger side was blowing cold. The driver's side was blowing the outside ambient temperature. This is odd to me so can someone give me someplace to start looking?

The refrigerant needs to be topped off.

The refrigerant needs to be topped off.

What would be the approximate amount? A pound? A half pound?

You got me there. I think the system only holds 2 - 2 1/2 lbs. and it is usually not enough to set a low refrigerant DTC so it can't be very much. I'm guessing 1/2 lb.
