1999 C230 Kompressor
Heating/ AC Controls lamps not working
Hi,
I just recently bought a 1999 C230 Kompressor, and some of the lamps that backlight the heater/ac controls are out. specifically, it's the blower speed rotary dial lamp, the drivers temperature control, and the rear heated window switch. The other two switches are fine, as is the passenger temperature control and the rotary control for air diverter.
Can anyone help me out and explain how to get replace the missing/out lamps. The most I have been able to do is get the knobs off. I have no idea where to go from there.
Much appreciated in advance.
Steve

You Need to replace the Bulbs in side the A/C Unit. I did this back in may, they are not expensive, like $4.00 each, you will need to replace both of them. You will need to remove the radio, unscrew Trim screws, and Remove the A/C Unit. Disassemble unit (partially) and remove bulbs and install new bulbs. Do in reverse order to install back. Should take like an 1.5 Hours at most and I Recommend highly to let someone at a body shop or a mercedes-benz technician to do this because you will need special Mercedes Tools to remove the radio and to disassemble the A/C unit with out breaking the unit.

Oh Darn it. I was hoping this could be done easily from the front side. without having to strip the fascia off. I haven't even seen any screws to remove the dash.
The radio isn't a problem as the guy who owned it before me had an after-market stereo installed. Disassembling the AC unit could be an issue though!I have seen as I've searched, there are two types of controls. The rotary dials like mine, and the second is a digital control (with digital display) - Is it a year thing (1998, 1999, 2000, etc) how some cars have the second and no the first like mine?
Thanks

There are two, the Digital which is standard on the C43, and on the Class from 97-98-99 the rotary dial knobs are standard on C230s, I don't really knows if on the C280 had the digital A/C Unit or Knob Units, but for for all C-class models from 2000 had digital units, including the sport c230, c280 and c43
