Bill, The attachment you sent was very helpful. I added refrigerant and I now have very cold air. Thank you!

I have a 98' V90 with 180,000 miles. The A/C when it works is not very cold. The compressor is cycling about every 15 seconds. The interior fan and the fan at the radiator are working fine. Where is the low side connection on this vehicle and do you think it maybe low on refrigerant?
