no heat for back seats
I'm not sure what the issue is possibly vacuum?
anyways no hat comes from the rear climate control console in my 03 s600
AC blows cold tho, heat is fine in the front seats.
rear climate control is on, mediumish fan setting
I've tried a number of different temp settings including high heat but after several minutes with engine running (dash shows 80+ water temp) there is no heat in the rear
any ideas?
