In a 1999 Pontiac Firebird, the orifice tube is located in the air conditioning system, specifically in the liquid line between the condenser and the evaporator. To access it, you'll typically need to remove the front grille and possibly other components for better access. The orifice tube is a small metal or plastic fitting that regulates the flow of refrigerant into the evaporator. Always consult a repair manual or guide for detailed instructions on your specific vehicle model.
either the owner's manual or the factory service manual
The Pontiac Firebird was produced between 1967 and 2002. The car went through 4 generations in it's life time and was also related to the Firebird Trans Am.
This year does not use an orifice tube but a expansion valve instead. This is located under the hood on the passenger side where the Refrigerant lines go into the evaporator under cowl (dash area) looks like an aluminum block. If it did have an orifice tube it would be located in the same place only inside the high side refrigerant line, or the smaller of the two lines and can be unbolted and separated to get to the orifice tube.

The question you ask is too involved for a proper answer. You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00
you have air in the lines bleed the slave
It is a common problem in most GM vehicles.
It would depend on the year for example a good condition but used 1997 firebird would go for about 7 to 8 thousand.
Give more info on what you have tried.. Go to question/answer # 19 on the Firebird faq's list, "If a 95 firebird starts right up..." Maybe this will help?!
My 1994 Trans Am does, it will go up to 110. I found out that the top speed of a 1994 Firebird or Trans Am is 156 mph.
go to the Pontiac dealership and see the parts man and he can help you out on that.
