This is normally caused by the dimmer switch going bad. In fact, I know of no other possibility, other than the low beam of the driver's side lowbeam input wire being pinched or cut in two. The latter is a very slight possibility, but is still possible. It is very much more likely to be the dimmer switch being bad.
One lady brought me her Merc Sable, with that problem...both her dim lights were blown,and would only work on hi beam....sigh...some people....
First check the fuses then change the bulbs it is posable for both to go out
The problem is probably in the dimmer switch but it needs to be checked out.
Check the bulbs Check Hi-beam circuit breaker/relay Check the hi/low switch
Check fuse # 33 - it states headlights , DRL , gauge cluster
around 200 feet :)
Check bulb Check socket for corrosion, power and ground
Most likely its a bad low-beam bulb or a fuse issue but I'd check the sockets/harnesses for corrosion, check the high beam switch, check wiring for shorts. See sources and related links below for bulb information.
These are both high resolution microscopes that both use electron beams.
this is my question and I was wondering because the day lights and high beams work but as soon as the low beams are switched on the daylights shut off. this is my dad's van, trying to help him fix the problem.
I'd be looking at a faulty headlight or stalk switch.
I would start with the easy answer. Check both of your headlamps to be sure that the low beam filament is still intact. If all is well there, I would start leaning towards the multi-function switch (which is the headlamp / turn signal lever.
the high beams are basically the same as your turn signals instead of moving the switch up & down push it forward
change your bulbs and see if that's it.
Check your owners manual.
If it's the same as the 1996 Ford Ranger , fuse # 33 is a 15 amp fuse for the High beam lamps
Bad bulbs or multifunction switch
If the high beams will not work on a 1997 Escort even after the relay was changed, it is possible that the bulbs are burned out. It is rare, but it does happen that both bulbs will burn out at the same time.
dont
your bulbs are burnt out. when you switch on the high beams its only the high beams. but when you flash your brights it lights up both high and low beams.
Answer: on the turning signal switch turn the handle forward for headlights. high beams pull in to flash. push out for high beams to stay on.
Bad low beam relay or dimmer switch
