97 E39 528 high beam problem - BMW Forum

Sugarmel · 01-30-2011, 07:13 PM

My right high beam went out and I replaced the bulb. However, it still is not working. Is there a fuse for eack head light? If so, where can I find it. I looked in the glove box and the trunk, but no luck. Thanks.

Can anyone shed any light on my post?

Have you checked the wiring and connections?

Hi,
It seems that there is a problem in dimmer connector. Check that one.
I am positive the problem is in dimmer connector.
Thanks

Dylan,

I just came across this thread and coincidentally I have the same problem with my 97 528i. Could you please provide more detail on the location of the dimmer connector? Also any specific details (i.e. color, size, etc.) would be very helpful. If you have a photo, even better. Thanks for your help. Fred

Did you check the fuse panel?
Does your car have fuses and relays? My high beam relay had died, and I didn't know ...
Trust nothing.

I checked all the fuses, would there be a high beam relay for each light? Where can I find the dimmer connector? The funny thing is that only one high beam that would not work.

Is there yet another fuse box under the passenger side?
ANYway, I'd start from zero. Get a multimeter.
Switch headlight bulbs, and check to make sure that both are good. If it's good on one side, it should be good on the other.
Check the light socket- they corrode, get cracked, wires get loose, etc. Check for juice and ground.
Check the fuse box- mine has relays and fuses, for left and right, and high and low. Check EVERYthing. Mine has those little rounded end PITA fuses, with miniscule contact points, corroded old connections, and loose contacts. Just because it looks good and checks out good doesn't mean it'll stay good or work good. Turn on the lights and wiggle connections.
ALWAYS check your grounds. Electrically speaking, your ground wires are actually the feed or supply wires, and they leak juice thru your device to the switch. If the switch works. Disassemble, make the connections are clean bright and shiny, and bolt them tight.
Check the wire to connector connection. If in doubt, solder it. Any doubt at all is good enough.
