I have a 1999 Saab 9-3, 2.0L turbo. 1. Where, under the dash, are the four (4) preasure switches that control A/C function, and where are they in relation to in-dash controls?2. How are they tested to determine if they are operational?3. How difficult is it to reach these switches, and how long should it take if procedure done by qualified Saab mechanic?

what more info do you need?
There aren't 4 pressure switches on this system.
The sensors and switches are tested using Tech 2 scan tool or equivalent.
Testing the system should take no more than 1 hour, however if component tests fail then fault finding the cause can take longer. ie. fault could be a broken wire away from the component under test.
the part of the first question that was not answered, was where are the preasure switches in relation to in dash controls???
The pressure switch is on the pipes under the bonnet.
Thank you, Rod Yemma
