I just bought a 2006 durango with a hemi, if the temp is 88 out my ac blows 48 at the vents is that normal. i had it to my local ac shop 3 times they replaced the expanision valve, the drier and the condenser. no help.any ideas? the rear ac blows the same 48.

 

88 to 48? That is a massive drop in temps and sounds better than perfect.

What are you trying to chill? Dead bodies from the morgue?

I agree with Indy, 48 degrees is 20 degrees cooler than what I set mine at and all is well,

I sorry. I posted wrong if its 88 out the AC blows 58 at the vents front and rear, if its in the low 70 it blows 48 to 53. The AC shop knows theres something wrong but they. Can't figure it out.

 

Generally speaking, 30 degrees difference between ambient and air temp at the vent opening is acceptable. I've never found the air coming out of the vents in the Durango/Aspen to be "freezing", but it's acceptable.

You should keep the air on "recirc" to maximize cooling during the summer, as that setting will allow the system to start with cooler, drier air than it would otherwise be pulling in from outside.

Do you have automatic climate control? If so and you're keeping it on the same temperature day and night, the system will adjust air temp accordingly. It wouldn't be unreasonable to only get a 22 degree drop in the evening when the control unit isn't trying to lower the temperature in the vehicle as much.

 

well that sucks i had a chevy tahoe that would freeze you out, this truck cant even come close. had the truck 5 months iam ready to trade it in...

 

To each his own.

My first generation Durango would lack in the 'freeze' department, but it would cool as well as my second generation Durango. My wife's Tahoe (her second Chevy) does have a better air conditioner, but lacks in the power department. An easy trade off for me as I perfer the power,

Again, if you have automatic climate control, make sure you have it set to the lowest temperature setting, and control the air output manually. The automatic a/c doesn't put out arctic air if you're only trying to cool down the cabin a few degrees.

If you have manual a/c, of course this doesn't apply.

Your personal thermostat must run pretty darn hot if a 30 degree air temp differential doesn't work for you!
