The low beam on my 1991 capri doesn't work ,only works on high beam and thats only if I hold the bright light switch can anyone help

High beam switch moat likely, have you checked relays and fuses?

Sounds like it's in the actuator itself - the part that you move on the steering wheel or dash to put the high beams on or the headlight switch itself.. Find the ground wire on the headlights and run a new wire from that directly to the body somewhere so it gets a good ground, or directly to the neg side of the battery.

replace the headlight switch

The high and low beam lights use the same power source, so if the low beams work the high beams have power.
There is a low and high beam relay controlled by the dimmer switch.
If the low beams work and the high beams don't, and the bulbs are good, check the dimmer switch and the high beam relay.

replace the light switch

No it sounds like a faulty turn signal switch. The entire lever controls turn signals and high beam dimmer switch.

the bulb is bad.

Hi,

Most of the time when the high or low beams don't work you have a bad dimmer switch. I would reccomend getting it replaced.

could be the switch. did you do anything to the switch when you changedheadlamps? maybe you put the lamp in incorrectly also did the brights work on the lamp that was "burned out"?

Clyde,

I've been troubleshooting this same problem on a different vehicle this week, and I can give you the steps I'd take.

1. If both sides went out at the same time, the problem is *NOT* likely to be the bulbs.

2. Check the fuses to see if both low beam lights are on the same fuse. Many cars have one fuse for low beam and another for high beam, so both lights out at the same time typically means fuse blown.

3. If the headlights are OK and the fuses are OK, then the problem is *LIKELY* the headlight switch. In my case, AutoZone has one and it can be installed easily; but in your case, that may not be as simple.

Please post your findings or comments.
