saflyer Posted February 21 Share Posted February 21 Went to the coach tonight. The two lights under the TV console were on. Nobody remembers turning then on. I tried to tap them off but no luck. Operating on battery power. Since they are both behaving the same way it must be a system problem. Where should I look short of disconnecting the house batteries?

saflyer Posted February 21 Author Share Posted February 21 12 hours ago, Dwight Lindsey said: Rotate your headlight switch to the off position Interesting. I was rotating the switch to see if there is a set screw or some such to remove the knob. I need to do that to remove the switch since my headlights don’t work, bright or dim. I only have parking lights. So that brings up the subject of how to remove the switch. I can access the back of the switch by removing the cover of the dash but need to remove the knob to remove the switch. How is this accomplished. Am I approaching this correctly or should I troubleshoot elsewhere first? Is there a good source for the switch? I have heard it’s an old standard that should be available at any auto parts store. BTW, thanks Tom for going easy on me. Link to comment Share on other sites More sharing options...
Frank Bergamo Posted February 21 Share Posted February 21 The switch has a button on it to release the knob. Wiggle the knob as you press the button and it should pop out. Hope this helps, good luck! Link to comment Share on other sites More sharing options...

I have a very limited view of it there due to the left vent hose obstructing the view. I could remove the hose but am afraid this will just introduce new problems. Doing it mostly by feel now.

Headlight switch knob removal - In my case it wasn't the switch, but after fiddling with several harnesses the lights mysteriously started working. I couldn't find any suspect connections . . . . Or in your case maybe it is the switch . . . - bob 1 Link to comment Share on other sites More sharing options...

Shouldn’t be a problem. I’ll go back out and try to locate the button again. Link to comment Share on other sites More sharing options...

I used a coin under my finger/thumb to keep from poking into said digit. You still have to fiddle with shaft and button. - b Link to comment Share on other sites More sharing options...

Bend the two tabs on sides and everything comes apart. *AND* (the best part) it'll go back together again! - bob Link to comment Share on other sites More sharing options...

They are all white and only a couple labeled and they were for panel dimming. Oh well, it’s off to the shop we go. Link to comment Share on other sites More sharing options...

cbr046 Posted February 26 Share Posted February 26 Again, driving home on I-20 last night the lights went out in Georgia. #$&%@!!! Pulled in a truck stop, wiggled all the harnesses & connectors on the pc board in the FRB, wiggled all the relays and connections I could find, went inside and wiggled the harnesses under the transmission, beat HARD on the dash, turned on the lights and they WORKED! Then I repeated all that wiggling and pounding with the lights on and couldn't get them to fail. Drove an hour today lights on and couldn't get them to fail. Oh, and my on-off-on Warning Light went out and stayed out after dumping the black & grey tanks. It had been on since leaving Friday. Never a dull moment. - bob Link to comment Share on other sites More sharing options...
