Ive purchased an 03 Disco with the rear air conditioning controls. Now that its cold out, I've noticed that these rear vents will not blow out warm air. Are these vents strictly for rear AC only? Manual is very vague and says you can turn them on to recirculate air, but the only way they come on is if you actually push the AC button. Thanks

 

Yep AC only, no heater core back there. Your manual only refers to it as REAR AIR.

 

Thank you!
