Pressure on guages

getsidewys on Sun July 20, 2008 4:29 PM User is offline

Year: 2003
Make: dodge
Model: 1500
Engine Size: 4.7
Refrigerant Type: 134a
Pressure Low: ????
Pressure High: ????

I have replaced the compressor, expansion valve, dryer. When adding freon(2 cans) the high side will go up till high pressure switch will cut compressor off. The low side shows about 70lbs till compressor cuts off it will go over 100 lbs. I have blown through the condenser and evaporator core with no blockage. Can anyone help me?

I see you did not list any pressures. Did you pull a deep vacuum?

Follow this vac/charge procedure and fill the amount listed on the under hood sticker. You can't have any air in the system, as Dougflas asked..
