Hi, you must be referring to the txv or metering device that meters freon into your evaporator coil. It is also called the thermostatic expansion valve. If you follow both the high and low side freon lines from the compressor to where they head back toward the firewall of the engine, that's where you will find this metering orifice. It is soldered or flared to the high side refrigerant line where it meters freon into the evap coil throttling back and forth as needed on a call for cooling. The coil is more likely a squared type and is sealed to keep out heat and everything else. You may have to excess from both inside and outside of the firewall as I don't have the book in front of me, but you will no quickly. I hope this has helped you out. If you need more information on this, and what the a/c is not doing, keep me posted. Best of luck to you,

Ac not cold cool but not cold

Have you recently added R-19 refrigerant to your Jeep? The 1989 model base requires R-19 Freon, not the newer R-134A designed for the newer cars...Has your stock system been re-fitted for the new R-134A refrigerant? If cool but not cold, the system could be low...or need a clean/new orifice tube...Try for a free inspection in your area...

Location of orifice tube in 2000 chevy venture

best advice is the method i would use to located the orifice tube in the 2000 chevy venture. check the automotive repair book section in your local library. Most libraries have repair manuals on their automotive shelf section. find the a/c manual for your year and model car. make a copy of the page that has the information you need. you will need to make a copy because the library will not let those manuals be checked out. you might want to google for the location of the orifice tube location. I hope this helps.

Where is the AC expansion valve on a 1995 Jeep Grande Cherokee?

For the 93 it is in the line before the evap core, should be about the same for the 95, unless an orifice tube was used in that model.
