Lights that won't energize have been replaced or tested for function and all are capable of activation. Ground shorts have been tested and eliminated.

Step one, at the headlight switch can you confirm the orange/yellow and orange/white wires to the same pin number in the connector have power with the headlight switch in park or head?

It is cold and dark here in N. California. So won't pull panels to access connections with DMM until tomorrow but when using factory dial there is no lights on park but head OK.
Expert:  Chris (aka- Moose) replied 3 months ago.

No problem, report back tomorrow when ready.

OK Panels off and head/park switch out. On terminal plug I get 12v dc on og/ye and 0v dc on og/wh
Expert:  Chris (aka- Moose) replied 3 months ago.

Since your not getting these results https://dl.dropboxusercontent.com/u/90220402/mainlight.png The first issue is the head light switch is bad. Unknown yet if there are wiring issues beyond the switch.

Moose-my bad.....in haste I tested pin 9 and 16. Testing female pin 13 (to 58L/R on male con) and female pin 16 (to 58 on male con) I get 0v dc? They both should be hot? How does that result in bad head/park dimmer switch?
Expert:  Chris (aka- Moose) replied 3 months ago.

When the headlights are on, the switch powers these wires to illuminate the lamps you're not getting to turn on.

Customer: replied 3 months ago.
OK I'm not too smart but if I DMM test the female connector w/o the switch inline how does that result in test of switch?
Expert:  Chris (aka- Moose) replied 3 months ago.

The switch is plugged up in this test. You are wanting to see if the switch is closing the internal contacts and using the power it is getting in and sending it back out on the different circuits. You push your meter probe in beside the wire to contact the end of the wire in the connector or push a paper clip in there so you can touch your meter probe to it.

OK I just installed the switch and tested pins 13 and 16 in park and head and got the 0 v dc reading. I have to order a replacement. Can you advise if ebay is good source? Looking at a switch listed at $19.99 at http://www.ebay.com/itm/2004-2007-Ford-Focus-Headlight-Lamp-Switch-Genuine-OEM-4S4T13A024/132004615062?_trksid=p2141725.c100338.m3726&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20150313114020%26meid%3De3c3632f37a74d85bffda47c05c31cd7%26pid%3D100338%26rk%3D2%26rkt%3D30%26sd%3D252521004836
It is listed for the 2006 ZXW SES wagon
Expert:  Chris (aka- Moose) replied 3 months ago.

Your guess is as good as mine on buying a used switch from ebay. We have all bought something used that turned out to be great and something that turned out to be a lemon.

One other test if you want is to use a paper clip and use the connector diagram. Connector plugged up or not. Jump from pin 11 to 13 then from 11 to 16 and verify the lights work.

0 v dc on pin 11
Customer: replied 3 months ago.
I just noticed R21 fuse for running lights is missing.
Customer: replied 3 months ago.
Fuse #30 was blown. Pin 11 now 12v dc. Culprit was the rear license plate bulb. When it shorted it blew the fuse.
Expert:  Chris (aka- Moose) replied 3 months ago.

That is odd you still had headlights with the fuse blown, I thought the only issue was the parking and interior lights.

Expert:  Chris (aka- Moose) replied 3 months ago.

Hello again Chris here,

  1. I have to assume you were not pleased with my help, because you have not replied or rated the post.
  2. What would you like to do regarding your question now?
  3. Do you still need help? Please reply I want you to get equal to or more than what you paid for.
  4. This post is coming up on the 7 day mark where it times out. That can prevent me from being able to post answers to your replies.

Thanks Chris
