I got the back A/C giving cold A/C air but..

I got the back A/C giving cold A/C air but the front is coming out as just simply air. Both blowers are working perfect. I fixed the back by bridging the "pressure switch connection" (that switch is bad-this is a temporary fix). I thought that would fix both the front and back A/C. The system is fully charged with refrigerant I checked it. How can I get the front going now? What else could be bad? Please help guys!!!!

Check the mercury villager forum there is a thread on this.
