On my 06 Lacrosse, I noticed something wierd yesterday while driving through town and I don't know if I should call my dealer and have the car checked. The A/C blower was turned all the way up. When I accelerate from a stop it sounds like the blower goes a little faster, also when idling at night the headlights will dim for a split second like the Compressor is coming on yet the Climate COntrol is turned off. Any ideas?

Kinda sounds like there may be either a battery cable going bad already. OR a possibly faulty battery. IF the compressor is coming on without the climate control on. It could be that there is a dead short in the electrical system. I would take the car in to have that stuff checked. Just to be safe.

Check all your battery cables first. Clean them up real good. If it still does it then we will have to look at relays for the compressor.
