yes but the a/c does wok the motor harder making it run hotter. condenser  
fan helps some

The Aux fan pulls air over the a/c condensor to help cool it  down.  It 
really doesn't impact a car overheating. If the aux fan doesn't  work, you'll have 
issues with the high pressure switch bidding farewell and  your a/c will not 
blow ice cold unless you're moving.
Also, be sure  and check the level of the coolant.  If it's empty, and you 
get an air  pocket in the system, you might see a jump in temps while  sitting.

Turning on the A/C should automatically turn on the aux electric  fan, if it
doesn't you could overheat (I guess).  Its very easy to  check, just turn on
the A/C and listen for the fan noise to increase.   You might want to open
the hood and directly observe the fan, just don't  stick your hand in there
as the fan can come on at any time and not just  when the car is on.


P.S. I had to  change my aux fan in my '98 A4 V6.  It wasn't too bad really,
mostly  just un-clipping the wireing harness in 4-5 places and removing one
screw  (I think).  I think there is a pretty good write up in the  AudiWorld
tech section.
