I read in another thread that by selecting "recirculate" the AC actually does come on. Can anyone confirm this?

I'm also having the constant hot air blowing problem and thought I had it solved by selecting recirculate, but I don't want turn the AC on just to fix this problem. This was allegedly addressed at a recent servicing but it's still blowing hot air.

Re: Constant Hot Air Blowing

Older cars had a cable type system, when you choose heat you simply moved a knob/lever on your dash to the red side and you had heat, the reverse for cool air.

This knob was connected to either a vacuum line which ran down to a vacuum heater tap somewhere under the bonnet.

The lever was connected to a cable then to the heater tap.

When you move either you opened the heater tap or closed it.

Using this principle why wouldn't the IDOIT service people simply block off the heater line (you only need to block one off to stop the circuit) running off the engine and take the vehicle for a run with just the fan running and no A/C (you could even disconnected the wire on the A/C to stop it coming on altogether) and see if it blows hot air

if it does it's the engine soaking heat into the firewall of the vehicle and heating up that way.............your buggered in that case except to say that Jeep need to spend some money on some proper insulation...

if it doesn't blow hot air anymore it's going to be whatever turns the heat on from the engine (remember the old school heater tap above) maybe the the heater/AC air door actuators/gears broken faulty....or something that turns on and off as you select the temperature you require..

My 2015 SRT does the same thing, it's winter here in Aus I'll fix it in the summer..

Re: Constant Hot Air Blowing

Picked up my 2015 SRT a few months ago (~3500kms). Just caught the tail end of the nice warm weather here in Melb, and noticed on hotter days, especially in stop start traffic, without AC on the climate just blows hot air regardless of the temp setting. Haven't tried recirc.
Now the cooler weather has kicked in I've found myself turning it upto 20-22 without the AC on as it's too cold.

These V8s throw out a bit of heat and I've just put the hot air in the cabin down to poor AC air intake placement. If you look in the performance pages at the engine intake temps they're pretty high. I've seen mine at 80C and that's pretty much behind the front right headlight.

If it's not supposed to be pumping hot air without the AC on I'd be interested to know, but I suspect it's a limitation of physics, nothing cooling the air you get whatever it comes in at regardless of what the climate control temp is set to.

Re: Constant Hot Air Blowing

I find the AC in this truck is shit to start with. Never blows really cold air...

Re: Constant Hot Air Blowing

The AC in my 2014 SRT works just fine, but they did have to replace the blend door gears, and they also said the system was over charged at the factory.... Normally in recirculation mode, the AC takes the air in the car and keeps re circulating and re cooling that air, rather than taking in outside air and cooling that... That way the system can drop the temp faster and often keep it cooler
