hi all<p>1.) Does the old wisdom about having the engine at low RPMs when turning on the compressor apply to the A4's climate control system as well?<p>2.) When changing windshield wiper speed from low to high or high to low, what is the optimal wiper position for doing this? (i.e. should I switch it at one of the extremes, or at mid-wipe?)<p><br>thanks all<br>-K. '99 1.8tqMS with turbo cricket<br>

Re the climate control: far as I kknow, compressor cycles on and off automatically, so doesn't make any difference when you engage it.<p>I have NEVER heard any recommendations on ANY car as far as when not to change wiper speed.

...than dreaming up these questions. Just my .02.
