Re: Radio Code and Overheating Problems

[Porsray@aol.com]

I am presently experiencing an intermittent problem with the radiator
cooling fan on my Coupe; the wire harness connector is cooked where
it connects to the motor, and is making bad contact.  Wiggling the 
connector will restart the motor until the next time it breaks contact
(anywhere from an hour to a week).  I have another connector on order
to fix this.

You might have to wait until the overheating condition starts, but one idea
is to see if you're getting power to the fan. Mine has 3 wires going to it;
the
brown is ground while the other two are power for the high speed (A/C and
overheating) and low speed (engine shutoff cooling).  Disconnect
the harness from the motor, and turn on the ignition and the A/C.  Using a
VOM, check the wires. The brown should be a dead short to ground, while
connecting a voltmeter from the brown to one of the other wires should show
voltage (prob. close to battery voltage, since it is the high-speed circuit).
 If 
you have power and the connector is good, the motor is probably shot. You
can probably connect 12V to the motor ground terminal and one of the other
terminals to make sure that it is a motor problem.  If  you have no power,
then
it is a matter of checking the relays, switches, and wiring.  If it is a
relay, I 
would suspect you would get partial fan operation under one of the above
conditions; if it is totally dead, I would suspect the motor or connector.

As far as the radio, suggestion might be go to a local dealer and ask them
for the proper procedure.  So long as they don't have to put their grubby
hands
on the beast, they (hopefully) shouldn't charge you.  Also, a call or letter
to
Audi of America should get results;l I have found them to be exceptionally
cooperative in providing assistance.

By the way, it might help if you mentioned year & model!

 Here we are a week later and my car is overheating.  The radiator cooling 
 fan is not coming on.  The turbo cooling fan comes on.  I will check the 
 thermo-switch tonight.  If it is not the thermo-switch, what are my next 
 options.  I notice that there are 3 coolant radiotor fan relays in the 
 wiring diagrams.  Are these susceptible to failure?  Anyone have any 
 thoughts?
 
 And finally, when the alternator was replaced, my bose radio temporarily 
 lost power and now is in the 'SAFE' mode.  My owner's manual says to depress

 the AM and the ARI-Z buttons, however, this is a factory replacement radio 
 and doesn't have an ARI-Z button.  I pressed the AM and the FM1 buttons 
 simultaneously and the display then read 1000.  I used the four station 
 select keys to correctly key in the correct code.  I depressed the AM and 
 FM1 switches again and the radio said 'SAFE' again.  What am I doing wrong? 
  After entering in the correct code, what buttons should I press?
 
 Thanks in advance,
