I have a 2007 X5 w/ 4.8i. It has 117k miles.

The a/c clutch went out recently so I replaced the compressor with a new Behr unit. After vacuuming the system and recharging, I am having intermittent issues.

When I start up the vehicle, the a/c system will no engage when pressing the button. It will begin to cool whenever the vehicle has been driving +40mph. Air blows cold after this, no matter speed.

If I turn off vehicle and restart, the a/c will not turn back on at idle.

Also, whenever I switched to heat, the air did not blow hot. What could be causing this?
