1998 lx470 front A/C won't get cold but rear will
 

The A/C on my LX is acting up. The front won't get cold ever. I was thinking it had something to do with a solenoid or something under the dash.

the compressor and lines were checked out by lexus and are all in good condition. When the compressor is on the line coming off it is pretty cold.

does anyone know what the different parts of the system under the dash are? Does anyone have the service manual or something?

thanks

My guess is servos aren't opening to allow the air through but the dealer really should have been able to resolve this for you. Do you have an indie who only does Toyota/Lexus near you?
