I started my car tonight and noticed despite the headlight switch being fully in the off position, my dash lights are on and my license plate light is .
Odd. Never saw that before. Headlight switch I imagine.... Thoughts? David Addedum-and saw what I thought was a wisp of smoke come from under my dash at the windshield....perhaps my imagination? |

Got out in the shop for a bit today and performed a few more tests.
This is what I found: With the cars harness hooked up to my spare wiper motor (known to be good), and the new 924 switch disconnected at the steering colum, the fuse holds! Another test, same as before but this time with the column switch removed from the column but hooked up to the wiring harness, the fuse holds and we have functionality at the wiper. I can only conclude the switch is somehow shorting/grounding when it's installed in the column. I have a notion what it is.... See the picture of the 924 switch below? Notice the circled area. That's where the 924 switch powers an electric washer pump. Also notice when I pulled (carefully-I have alot of practice at this point) the switch, this lead was seperated. It appears as if this connector may be touching the bottom of the column housing. I need to look at other things too but that's the first suspicion. |
