Hey guys, check this one out. I live in Miami, fl. It is usually hotter than the sahara desert down here so a\c is a must. When I have the a\c on and pumping it fluctuates, the speed can be all the way or near all the way and if you put your hand in front of a vent you will notice that the pressure fluctuates a little. Anyone heard of this? Also the weirdest issue I have had is when I dial Onstar thru the car the a\c will automatically swith to auto???? weird.

Any Ideas?

Thanks

When you push the onstar button the A/C automatically switches to auto so that the blower level can be ruduced. Basically the goal is to reduce background noise during the call.

I dont understand your first question/comment.
