Hello all, I'm new here but info I gained here sold me on my Xterra. Just recieved my 05 OR 4x4 in Night Armour 1week ago and love it. Was a big change going from a Bimmer to an SUV but don't regret my choice at all. Now the big question has anyone else here noticed the AC compressor runs as soon as you turn on the fan. AC switch is off and temp knob is turned to heat. I thought ac compressor only ran with ac on, am I wrong?
