Did you replace the dryer as well, in addition to the condenser? If you are bypassing it successfully it could only be the switch or the dryer. Also, from my understanding any time the AC system is "opened" you are to change the dryer. As mentioned above you can also troubleshoot the switch with a multimeter.
Last year i did the 2 hoses, liquid line w/ orifice tube, condenser, compressor, and dryer. I screwed up and did not put enough oil.... was getting 65 degrees out of the vents... evacuated the system, changed the dryer again and added the correct amount of oil and now blows 55 degrees out the vents.
