RVBLDR Posted February 24, 2007 Share Posted February 24, 2007 The right side of my heater contol unit remains dark, as if there is a light bulb out. The left side is fine. All the info appears OK on the LED screens and is readable, just harder to see. Is there a replaceable light bulb in this unit? 1996 ES300. thanks Quote Link to comment Share on other sites More sharing options...

They said it has bulbs and it would only cost like 1-2 per bulb. and you can do it yourself. Quote Link to comment Share on other sites More sharing options...
