Hi friends, this is my first post in this forum. We own a 2011 Sienna LE. The A/C is not blowing cool air at all when the van is stop. On a highway, you start feeling cool air. I checked the refrigerant pressure, there is no refrigerant loss, the high pressure is at 225-250, but the low pressure is at 85 psi. the low pressure will not go down even when running at high rpm. I think the valves inside the compressor are not working. The compressor is a Denso 471-1017. Is there any outside valve that may be preventing the suction of the refrigerant? I noticed the compressor has like an outside lever of which I don't have a clue of what it does. Please reply of possible causes or tests. Thank you.
PS. The cabin filter was cleaned and still no cool air at idle.
