rear vent blowing heat
hi,i have got an issue here,wen i am enjoying nice cool air con and it has the full 4 airtronic aircon then after 20-30 min the rear air con vents will suddenly blow out warm to hot air,and to correct it i will need to turn the temp setting all the way to HI setting then back down again to fix it??Then i will do this again may be 30 intervals??

This is a common problem with the E's.......I had the same problem.
I can't remember the exact name but it is some kind of air con valve that is located in the engine bay. The part is probably less than $10 in value, however, the task is quite labour intensive....so I was told????
