Agpopp Posted April 1, 2023 Share Posted April 1, 2023 Currently sitting in a Walmart parking lot after my headlights lights began to flicker then lost them completely. This is a new to me coach and I just replaced the switch before the trip as I found it had no dash lights. We are on our way from PA to Orlando. I took the switch out of the dash and was jiggling while driving trying to get to somewhere I could pull off (it was absolutely dark and I drove about 25 miles with marker lights using the car traffic for lighting.) Now I don't know if it's a short in a headlight or the new switch from Advance auto. I looked for breakers in the front wheel box but only fuses for marker and tails. Any thoughts on this?

It's in my signature, but I'll definitely write it from now on. 2006 Neptune 36PDQ I have a 2022 Ram Toad but the lights are working on it just no headlights. I did have the sensation of something clicking in the switch while I was holding it trying to get something to happen. And I can't believe I left my spiral bound owners manual on my TV table! And it was raining and misty from truck traffic. Link to comment Share on other sites More sharing options...
Ivan K Posted April 1, 2023 Share Posted April 1, 2023 No high or low? They should be on different breakers unless they have just fuses but that should not cause a flicker. If neither works and no diagram available, I would suspect the switch since it is the last part you replaced. A voltmeter would be useful to test it out for voltage and short. Hopefully no smart wheel involved. Maybe someone here has the charts for you. Link to comment Share on other sites More sharing options...

I'll jump around and see if I can get them to fire up, that would point to the switch itself. Otherwise I'm in for some wire chasing. Link to comment Share on other sites More sharing options...
rvtips Posted April 1, 2023 Share Posted April 1, 2023 Most if not headlights are on there own breakers that should reset it's self.I don't think you will a fuse for head lights. Link to comment Share on other sites More sharing options...

bobdinsmore Posted April 1, 2023 Share Posted April 1, 2023 If you're feeling a clicking in the switch, current overloading is a possibility and you're feeling the thermal in the switch opening and closing. Are they high-wattage bulbs or did you just put in higher-wattage bulbs? If so, install a relay to offload the current in the switch. There's a recent thread on this problem and solution.

Agpopp Posted April 1, 2023 Author Share Posted April 1, 2023 No special bulbs that I'm aware of. Especially as poor of light they emit. I jumped around the switch for now so I'll have to watch the jumper wire. Link to comment Share on other sites More sharing options...

bobdinsmore Posted April 1, 2023 Share Posted April 1, 2023 The headlight output on my 2000 Diplomat was really lousy so I put in 55w bulbs and this is how i found the much higher current (heat) the switch had to handle. The stem of the switch got very hot to the touch so I offloaded switch with a relay. Problem fixed. Feel the stem to see if this might be the problem.

Chuck B 2004 Windsor Posted April 1, 2023 Share Posted April 1, 2023 You might want to keep in your mind that most all parts that come from stores like Auto Zone and Advance Auto are factory seconds. That is why I only use parts from NAPA stores. Chuck B 2004 Windsor Link to comment Share on other sites More sharing options...

Wire never felt hot with the lights hard wired on for 14 hours so it must be the replacement switch was bad out of the box. Link to comment Share on other sites More sharing options...
Floyd4949 Posted April 2, 2023 Share Posted April 2, 2023 (edited) I believe this is the switch you are looking for. https://www.amazon.com/gp/product/B000C9SAJC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Edited April 2, 2023 by Floyd4949 I included unnecessary info Link to comment Share on other sites More sharing options...
Agpopp Posted April 3, 2023 Author Share Posted April 3, 2023 Thanks all. Got a new better quality "premium" switch today at Advance because there was one nearby. Completely different quality, so I hope that's it. Link to comment Share on other sites More sharing options...
