Some are in the inlet to the evaporator and some could be in the condenser line. You can get a new orifice tube on autozone for $5 - 20

They are located behind the right front headlights (passenger side). There is a bank of four relays mounted on a common holder. The four are for various purposes, one of which is to control the ac fan on the low settings. I got a bank of four used relays from and olds off of ebay. I plugged in the part number off the one I had into the search box to find it.
If a relay is bad, it will usually rattle.

Hello cptlarry: My name is Roger and I can help you. On the passenger side of the engine compartment. Locate the high side A/C line. This will be a small line called the liquid line. Follow it to the condenser located in front of the radiator. After removing the freon you can split the A/C coupling at the radiator. There are two lines split the one that goes back to the firewall. The orifice tube will be in the condenser end of the line.
Should you need further help please just ask. Please rate the quality of your answer as this way we know you received the correct information. Thank You for using Fix Ya. Roger
