I've never thought my AC was very good. That thought was proven when I got in a 2002 Taurus company car last week and realized the AC on the 9 year old 155k mile Ford was WAY better than my KK. I've had the AC EEPROM flash done and couldn't tell any difference. Has anyone put a set of pressure gauges on their KK? Can someone give me some idea of what high/low pressures I should have?

The high/low pressures will vary due to outside temps,humidity level,and elevation.

Just remember the car has alot less interior space to cool then a KK does.

I've noticed the same on my truck. My mom has a 2010 KK aswell and in her truck its much cooler.

Your AC may need to be recharged. I have an 08 and the AC works ok. I usually keep it on the second fan setting once it starts to cool off and I never have any problems. I also live in Seattle so it never really gets that hot, which might help.

I have a 2010 KK and am not thrilled with my AC. I think the problem lies in the power of the fan.Mine gets plenty cool enough, put the fan is not very strong. I had a Mazda Tribute before this and that fan would make your hair stand up! Fords seem to have very strong fans. It will kick up the fan speed some if you use the cabin recirculation (push the fan button in,it has an on light just like the temp button) I live in NC with a dark grey KK so I neeed cool!

Could the Cabin Air Filter be part of issues at all??

Yes.

Could be... mine doesn't have a cabin air filter (I'm not sure that any of the sports do, someone correct me if I'm wrong).
