Did you pull a good vacuum?
Does it blow colder when you are going about 60mph?

 

[BIG_KID]

Was the system vacuumed down?
How much freon did you put in ?

 

[98vortec]

yes vacume dn for 45- 1 hour and let set for another 30 min and vac was at -30in the whole time then i put in 3oz of pag 46 oil plus compressor was shipped filled with oil too and then 20oz if freon and maybe half another can that had 20oz in it soo bout 30oz of freon total

Need more information. Does it work better at 60mph vs sitting still? Why did you replace the compressor? If it was due to failure you should have replaced condensor as well. The R134A ones cannot be flushed.

Maybe the blend door is not working correctly, ie. air is not being totally directed through evaporator.

i replaced condenser and orfice and drier and lines and compressor and the truck has 437k miles i figured compressor was orignally soo i replace almost everything..

 

[98vortec]

is the inlet to the condenser be upper?or lowwer? cause the line from compressor is connected to loower and the line leaving is connectedupper where the orific is

 

[98vortec]

well i might have messed up... i have the lines connected correctly but i was looking at my bro truck which is same truck 98 his line coming from compress is connected on top and the outlet is on bottom i gathered that my condenser is upside dn soo my condenser outlet is up top and the inlet is at bottom which i have my lines connected correct but condenser is physically upside dn would that cause my problem?

I've never seen it on any vehicle where the lines can be connected backwards. Your low side line is always going to be bigger than the high side line and the fittings will accommodate that. You still haven't answered whether the a/c works better when the vehicle is moving. This would be useful to know if you want to solve your problem.
