check out the

A/C circuits by clicking menu #14 on my web page and performing the Operational Check: - Reading Sensor Values from A/C System to see specifically the following two key items:

1) the evaporator temp (#5) <-- sb oscillate around 37F to 43F
2) the compressor pressure (#7) <-- should vary from 10 to 15

These two items will give you an indication of the A/Cs state of health.

Also . . but he said it was a problem that needed addressing soon. Need to find out what this is asap! Suggest that he fix it if he wants to sell the car.
