    None of my ventilation system works. I check all fuses and they seem fine. Can anyone tell me how to trouble shoot this?

    Assuming the fuses are okay, check that the A/C relay (P) is working, then lift the centre consol and check that you are getting power to the switch assembley(#33) also check the fuse in the speed control unit(#32)
    Chech for power supply to the internal temperature ECU(#24)

    Check all grounding points behind the fuse box and relay board.

    If you need a detailed wiring diagram I may have one.

    I could use a detailed wiring diagram for an '85 QV Mondial Cabriolet. Specifically for the rear window interlock switch and fog light switch in the drivers console. The wires are color coded and the switch is not, so it is not clear which wires go to which terminals on the rear window interlock switch. And, I need to replace the fog light switch and have the same problem with which wires for which terminal.

    Is their an easy way to pop the whole cluster of switches out rather than individually as their is not a lot of slack in the wires to pull the switch out to work on plugging the wires into it.

    Thanks!

    That fuse box is a pain in the a$$ especially when it becomes a teenager.
