Heater problem W124

[Kully E220 Coupe]

Hi guys,

I got a problem with the heating system it only seems to blow out cold air on passenger side, i have disconnected the duo valve and i have heat on both sides (duo valve defaults to hot air when it has no power) so now i'm assuming that the dials that control cabin temp are at fault well atleast the passenger side one. Question is how do i get to the back of these controils so i can test them or replace them??

Thanks,

Kuldip :roll:

Remove the knobs by puling them off, then undo the 4 screws holding the wood trim in the dash, 2 topand 2 bottom. You will then be able to remove the pael containing the PCB and the wheels.

Good luck.
