Could be an incorrect refrigerant charge in a/c system
A 2004 year model vehicle uses R134a refrigerant.
Low refrigerant charge? Bad compressor?
You can find the refrigerant charge port on top of the air conditioner compressor. The refrigerant charge port will be labeled as the low pressure port.
from the factory, r-12 retrofitted to r134a if you have ever had a recent refrigerant charge. r-12 was found to be enviornmentaly hazardous.
Your recharge your air conditioner with the type of refrigerant which it was designed for.

1- Connect gauges and check system performance to determine if refrigerant charge is correct. 2- If charge is low, locate the leak. 3- Isolate leaking section of system if possible otherwise remove entire charge to proper levels and repair leak. Pressurize and check the repair. Evacuate affected portion or the entire system to proper levels. 4- Correct the refrigerant charge with the proper refrigerant and check system performance. 5- Disconnect gauges and replace all covers and flare caps clean up area. 6- Write up service report, have customer sign and give them a copy, get check from customer.
The amount of refrigerant a unit contains depends on the size of the unit. That is the standard charge but the charge after the system is installed may be more or less. The system charge depends on the size of the refrigerant lines, the length of the lines, and the size of the unit.
if system is empty, u need to charge with correct amount of oil and refrigerant. the oil actually carries the refrigerant in the system if just recharging, buy the refrigerant that has oil already added, these are available at most auto stores
Low refrigerant charge?
Could be a blown fuse or low refrigerant charge
