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? |

Well duh me.
On the learning curve. Slot 5 of the steering column wiper switch (see previous post) wouldn't show continuity at the wiper motor pin 53a cause the secondary rd/blk wire coming from 53a doesn't go to the connector. It goes to the power side of fuse 8, then off to the horn and fan relay. Pin 5 of the connector is un-used. They all came wired for the optional "intermitent" (see 91 of the schematic) feature. You can find that wire in the forward trunk and test continuity from it to the connector slot 5. Essentially that means to if your having a fan problem or a horn problem that'd be a place to check for continuity and or power (but don't be decieved, fuse 8 can be powered up from a number of other sources. A continuity test on the actual wire is best), the secondary rd/blk wire from the wiper 53a down to the load side of fuse 8. But in terms of the wiper connector it's meaningless unless your testing for an intermitent wiper feature. Sooooo, what does this mean for the happless me? Through the process of elimination, not only was my stock switch bad (no continuity between pin 1 and 2 in high position), but apparently the switch from CIP1 was either bad or that part (remember, I got the VW one for the super beatle or 924 to power an electrical washer pump) isn't gonna work. When I test the switch, the farthest innermost terminal on the left is supposed to have continuity between pin 1 and 2 when in the high position. It doesn't. It has continuity from pin 1 and 3. Either miswired or that mod doesn't work. CIP1 is shipping me a new one so we shall see.... And let us not forget, the currently installed wiper motor is also bad (compounding the diagnosis) as 53a is zero ohm (tested in isolation). Fortunately I have a spare pulling 1.9 ohm. Can I get a freakin break on these damn wipers? And to think, this all started with dashboard and license plate lights coming on inappropriately.....(a problem for another day) |
