It seems like the front ac in my ex isn't blowing very cold. The rear seems to be blowing colder than the front. I checked and it seems to be ok on freon. Any tips to help the front cool down some more?

 

The heater core always has water flowing through it. If the damper door has opened it will allow hot air to mix with the cooled air. Most common cause is a vacuum leak (see the other A/C thread going right now) but also the doors can sometimes stick. If you don't have a vacuum leak then put the system in manual mode and work through all of the combinations of air direction and A/C vs heating.

 

Mine has blacked out twice on me but came back on after booting up

 

you have 4x4 w/esof? Does air blow out defrosters? Could be vacuum leak in front hubs.
You have manual A/C or auto HVAC controls? Verify blend door is working, try changing temp to observe change.

There is also a small vacuum actuated valve on the heater hose (just above the a/c lines near firewall) the grey vacuum line often comes loose.
This valve blocks heated coolant from flowing through heater core to increase front a/c cooling.
