I have a 2005 RL. My A/c compressor works properly but the vent settings doesn't work ... constant hot air from the face and floor vents. When I turn the temp low I get cool air out the passenger face but hot air from all the other vents (driver, rear, Floor). I ran the self diagnostics and the only thing that came up was COMP Solenoid Error. I'm not sure what to check or do next .. please Help.
