Heater controls

My o4 has no light in the left 3rd of the heater controls, has anyone succesfully fixed the control lights.???

My lamps are also on the way out. I will be taking the panel out soon, but so far I get them to work by giving the panel a good rap and they come on. Try this link for what's involved. The lamps are mounted to the back side of the climate control : https://sprinter-source.com/forums/showthread.php?t=6084&highlight=climate+control

You can buy the lamps and replace them. It involves quite a bit of removal and separating the circut board from the controls. But it can be done. I felt it was a lot of work for one little tiny lamp. I think I did break a bulb in the attempt. But the replacement package had two or three bulbs in it.

Spray lube (I used a graphite spray from Lowes hardware) the cables that are attached to the air flow control knob while its out. Get the lube into the tubes that that cables run thru - it will move a lot better. There are 2 lights to change and its a lot of work to get to them - take advantage of the access while you can.

i found with mine when one of the blubs went that the light carrier"its a clear plastic light diffuser of sorts"had actually melted with the heat of the bulbs,there is no fix or replacement part and if you like your lights a new control unit is the only option.the bulb is near impossible to replace and requires having to bend both plastic housing and pcb to remove the bugger.

have fun.
