Low beams not working

Four cylinder front wheel drive automatic 55,000 miles.

My low beams suddenly stopped working. My high beams work fine.

I have checked the fuses, and the bulbs.

Any ideas as to what to look at next?

Thank you,

Hi Ed,

Thank you for the donation.

Is your vehicle equipped with daytime running lights (DRL)?
Is it with Autolamps?

Check the headlamp relay in engine compartment relay and fuse box). Low and high beams uses different relays for their circuit, try swapping them to test.

The car does not have running lights. It does not have autolamps.

I swapped the fuses for the low and high beam with no success.

What is the headlamp "relay?"

Thank you,

Ed Marshall

Here is a diagram of the relay box.

Swap E48 and E51 and if the low beams comes on and High beam goes off, the relay is bad. If both works now, check the terminals of the low beam for looseness and signs of overheating. If none found, replace the low beam relay, it is failing and intermittently bad.

I swapped the low/high beam relays.

I still only have high beams.

Thoughts? Ideas?

Could there be something wrong with the on/off switch on the handle?

Thank you,

The relays swaps confirms they are in working condition.

Yes, the fault could be with the light switch.

At the light switch, ground the Red wire with a test lamp and check if the low beams comes on. If yes, the light switch is faulty. If light does not come on during this test, get an assistance to licsten for the low beam relay clicking while intermittently grounding the Red wire.

If relay clicks, the fault lies with wiring between the relay and headlamps. When you unplug the low beam relay, there must be two terminals that are hot at all times.

So the light switch at the end of the handle on the steering wheel post. The same handle that is used for left/right signals.

How do I get to it? Do I need to take apart the steering wheel post housing?

This sounds like maybe I need to take it to a dealership or local repair shop.

Do you think a guy w/average mechanical skills can tackle this? I use to do all my work on my VW Beetle :>) and I have a pretty decent complement of tools.

Thanks again.

A normal DIY guy should be able to handle it but if vehicle is equipped with air bags, care must be taken to avoid damage to the spring reel under the steering wheel.

You would have to remove the steering wheel and column cover to get at the light switch if it is for removal. For testing, removal of the steering column cover should do. There are a few attaching screws and after removing them, you should be able to pry the covers apart to get them out.

From there you should be able to perform the test.
