  • Heater Control Problem

    It's been a while since I looked in, but hopefully someone can help, my 07 reg 450 has developed a fault with its heater control. The problem is the slide will not go to the very ends of its travel in the slot which shows the temperature settings. It will not reach the coolest setting, (no problem at this time of year!) Nor will it reach the hottest one a real problem, when traveling a round the Welsh Hills where I now live when the temperature is -6! The slide will travel in the middle of the slot, but when you reach the final quarter it springs back to the middle! This has happen before, but has freed it self. Any ideas welcome, many thanks.

    Must be something snagging it. Time to dig in and find what. There should be something about dissembling it on FQ101 or Evilution as there is another common problem with the blower control.

      There's some info on Evilution but you have to register to see it all.

        Most likely your carpet is in the way!

          Quick update, the other half took a look yesterday, she removed the radio and was able to access the slides (levers) from underneath! Small sized hands help, and somehow managed to get the slides back onto their tracks.

              What distance should be reached to reach 3 blobs? A maximum of 8km should be enough.
              If this is not the case, then you have air in its engine cooling system
              lack of antifreeze or defective thermostat.
              1.Check the antifreeze level
              2. Remove the air from the cooling system.
              3. If not resolved but the temperature does not reach 3 blob then change the thermostat.

              Usually an air bag is formed in the heating matrix.

              The heating matrix may also be clogged - a washing them solve the problem.

                  Hard .
                  The face should be removed.
                  We must dismantle the dashboard.
                  The matrix case must be removed (altogether). Uncover the casing carefully.
                  The seats, the doors, the windscreen and the powertrain remain ...
