headlight issues
I've noticed lately, that sometimes the headlights seem to dim for a split second, and then go back. Not even long enough to see it on the ammeter.
Outside air temp has no effect, nor does vehicle speed. the dimming isn't consistent either (as far as time between dimming). Any ideas ??? |
just after startup?
heater grids cycling.. totally normal. |
no, any time...even after driving for many hours.
the dimming is no where near as noticeable as the heater grids. |
You might have weak batteries or a alternator problem? I had a 2000 Jeep and it did the same thing, in the end it was a problem from a weak battery!!
|
For what its worth:
Mine did it last night and tonight again and about 2 hours ago the left headlite burned out. |
mine is doing the same thing right now daytime lights acted up drivers side went out but when I turn the switch on they both come on ... now that always does not work I have to cycle hi/low beam to clear it up but the dimming is still there from time to time I suspect something to do with relay's cant play with it now -23'C outside ( windchill -32'C ) :)

If you don't use your brights much it could be the multi-funtion switch (turn signal) is dirty causing a poor contact. Spray electronic cleaner at the base of the lever while working the dim/bright and left right turn function back and forth.

Well, infidel, as usual, you may have hit on the issue.
My multi function switch is acting up and I plan on replacing it soon. it doesn't always 'park' the wipers. it's been doing it for months now, but I only drive it once or twice a month (too long for daily driving & parking and too long, wide, and new for hunting with). Have to see what happens when I replace the switch |
