Rear A/C is a lot colder

['04excursion6.0]

My rear A/C is very cold but my front is only cool at most. Anyone else have this issue?

btw it's a '04 limited with automatic A/C.

I know this post is from months ago, but if you're still having this problem, check the vacumn controlled valve in the heater hose (passenger side, top of motor). If the vacumn hose comes off, heat will flow in the dash. This has happened to me before.
