@Reg 65 . Sorry mental abberation, must be an age thing creeping in. I meant to point towards
@airwave , who depending on his journeys, may be available.
Hmmm , did someone use my name in gest here .
Okay
@SimonNewDesign , forgive me , as i'm a little on the drag here , and i'm not totally sure what you're asking here . But it appears you're confused over the heater speed , or should i say blower speed rotary control position .
Now first off , and this may be important , my vehicle is a left hooker , ie the steering wheel is on the wrong side . But other than that yes it is a 230 , and yes it is a year 2000 .
The control in question is nearest the driver , ie on the left . with the temperature control in the centre , and the outlet selector over on the far right .
One further note i'm gonna add , is my van has a three speed heater blower as well . Now i'm not fully up to date with this one , but there was an issue with the four speed motor , which basically melted the fuse box . If i remember correctly the block would melt due to the heat produced by using the fourth position over extended periods . I would wager , a modification was made to prevent this happening , by reducing the speed available , and hence lower the actual heat produced . In reality i doubt this worked , as after only a matter of weeks after buying my van , i discovered my fuse block also damaged , and a separate in line fuse fitted . Comically the circuit was joined using 10 amp connectors , when the actual fuse was rated at 30 amp , hmmm big red flag there . Though returned to standard form now with the fuse block replaced , it took me four years to locate , and secure from a breakers in Lithuania .
I'm gonna attach a picture here , but be warned , this is a heavily modified dashboard (only recently completed) , but was a standard x230 .
This is what i have now , but just to reinforce it was a 230 , i started off with this (though this is not actually my van) .
Now with reference to the attached file you sent in post 3 , the posts you mention are important as there is an under tray which screws to the outer most dash panel , which basically holds the heater illumination . The white panel in this picture here (ignore the switch to the the lower right of the tray , as it's part of my modifications) . These screws are hidden behind the rotary dials in the fascia .
Now the important part , is this under tray attaches to the rotary set by four screws , one in each corner . Hopefully you will be able to make them out in the picture above (note the screws attaching the tray to the outer most fascia are also visible under the rotary posts) .
However the problem is , i never went any deeper , so my knowledge is now lacking . But looking at the above picture , you can clearly see yet another under tray , with which i suggest the dials have to be attached !! .
Have you taken the panel apart yet ? . And do you have any photos ? .
